In the Notice of Intent, the government committed to develop and implement an integrated, nationally-consistent approach to the regulation of industrial air emissions. In November and December 2006, extensive consultations were undertaken with the provinces and territories, industry, aboriginal groups, and health and environmental groups on elements of the proposed approach and the development of the regulatory framework. A companion document 2 was published to further elaborate and present elements and options for consultation. These consultations and the public comments received in response to the Notice of Intent have informed the development of the regulatory framework.
This section presents that regulatory framework. The regulations will mandate reductions in emissions of greenhouse gases and air pollutants from the following industrial sectors: electricity generation produced by combustion, oil and gas (including upstream oil and gas, downstream petroleum, oil sands, and natural gas pipelines), forest products (including pulp and paper and wood products), smelting and refining (including aluminum, alumina, and base metal smelting), iron and steel, iron ore pelletizing, potash, cement, lime, and chemicals production, including fertilizers.
For greenhouse gases, the framework sets a 2010 implementation date for emission-intensity reduction targets. For air pollutants, the framework sets fixed emission caps that will enter into force as soon as possible between 2012 and 2015.
In order to minimize costs to industry and the impact on the economy, the framework contains compliance mechanisms intended to provide industry with flexibility in meeting its regulatory obligations. The framework also requires rigorous monitoring and reporting in order to ensure compliance assessment and transparency.
The short-term targets are expressed as reductions from 2006 levels. To support the development and implementation of regulations, comprehensive and consistent baseline data for 2006 will be required from facilities in the regulated sectors. To this end, the government will require facilities in those sectors that will be covered by the regulations to report 2006 emissions and other relevant data under a notice issued under section 71 of the Canadian Environmental Protection Act,1999 (CEPA 1999).3
Preliminary analysis of environmental modelling and assessment of the environmental and health benefits and economic costs of the industrial regulatory targets have been completed and are presented in this document. Further analysis is ongoing, and continues to support discussion on the proposed framework.
The government will validate the benchmarked air pollutant targets over the next several months. The government will work with industry, provinces and territories, labour, and environmental and health groups during the validation process. The regulatory framework for air pollutants – that is, the targets, the compliance mechanisms, and the timeframe for the entry into force of the regulations – will be finalized by fall 2007, after the government has validated the benchmarked air pollutant targets.
While this validation process is underway, sector-specific regulations will be developed for the general provisions and those related to greenhouse gases, leading to publication of the draft regulations in the Canada Gazette, Part I, starting in spring 2008. The regulations will be revised to incorporate the air pollutant provisions a few months later, following normal regulatory procedures.
The government will monitor the evolving regulatory framework as the regulations are developed and implemented over the next two years and will make adjustments, as needed.
In addition, the government has committed to review the regulations on industrial air emissions every five years in order to assess progress in reaching medium- and long-term emission reduction objectives. The first such review would take place in 2012. The review would entail an assessment of the effectiveness of measures taken to reduce greenhouse gas emissions and air pollutants, and of advances in industrial technology (energy production, industrial processes, and pollution abatement) in order to determine the potential for further emissions reductions consistent with the goal of continuous improvement. The review would also examine the state of air quality and possible changes in the Canadian industrial sector mix, including regional changes, that could affect the goal of achieving tangible benefits for the health of Canadians and their environment.
The federal government will set stringent national standards and will work to reach equivalency agreements with those provinces that set provincial emissions standards that are at least as stringent as the federal standards. Equivalency agreements will allow provincial leadership, while ensuring a nationally-consistent level of health and environmental protection.
As the proposed federal regulations are developed, the government intends to work with provinces and territories to avoid as much as possible any duplication and to ensure consistency in the way in which regulations are applied.
Most provinces restrict the emissions of air pollutants. However, standards vary considerably across the country. Alberta has also recently released draft regulations to reduce industrial greenhouse gas emissions in its territory.
Since the federal government recognizes the important role played by the provinces and territories in air management, work will be undertaken with interested provinces and territories to make the best use possible of equivalency agreements.
When an equivalency agreement has been reached, the Governor in Council can suspend the application of the specified CEPA 1999 regulations in the signing province, so that only the equivalent provincial regime applies. The federal Minister of the Environment remains responsible for reporting annually to Parliament on the administration of the CEPA 1999 provisions that permit these equivalency agreements. CEPA 1999 authorizes the Minister to enter into an equivalency agreement with a province, territory, or aboriginal government if the Minister and the other jurisdiction's government demonstrate that there are provisions in force in that jurisdiction that:
Provincial enforceable certificates of approval or permitting or licensing systems can be recognized as a basis for an equivalency agreement. Once an equivalency agreement is negotiated, the Governor in Council may make an order declaring that the provisions of the CEPA 1999 regulation that are the subject of the equivalency agreement do not apply in the jurisdiction of the particular province, territory or aboriginal government with which the agreement has been negotiated. The result is that the regulation (or portion of it) would "stand down", leaving the subject matter of the CEPA 1999 regulation to be governed by the laws of the province, territory, or aboriginal government with which the agreement was negotiated.
Short-term emission-intensity targets
The government will put in place short-term emission-intensity reduction targets that will come into force in 2010. These targets will result in absolute reductions in emissions of greenhouse gases from industry as early as 2010 and no later than 2012, even if the economy grows as expected. The targets will also make a vital contribution to the government's commitment to reduce national absolute greenhouse gas emissions by 20% from 2006 levels by 2020.

The government is introducing the toughest action on greenhouse gases ever proposed by a Canadian government. The government's emission-intensity targets are 6 percentage points more stringent, at 18%, than the emission-intensity targets proposed on July 16, 2005, at 12%. Unlike the 2005 proposal, this plan also requires annual improvements in emission intensity of 2%, meaning that, by 2015, a 26% emission-intensity improvement will be required under this plan.
Short-term mandatory reductions in greenhouse gas emissions by sector are defined in terms of reductions in emission intensity from their emission intensity in 2006, the base year. That is, greenhouse gas emissions per unit of production are capped. The regulatory release limit for individual facilities within a given sector that will be needed to achieve this overall percentage reduction will be determined as part of the process to develop the detailed regulations.
The emission-intensity approach ties targets to production. This means that firms will not be able to claim emission reduction credits by shutting down production for economic reasons or obtain credits for moving production out of Canada. Rather, credits can only be earned through cleaner production. More importantly, these rigorous targets will yield absolute reductions even as the economy grows. As the World Resources Institute noted in a 2006 report, "[f]or environmental performance, what matters overall is that targets are set at reasonably stringent levels and subsequently are met. This may be achieved with absolute or intensity targets".4
For comparison purposes, greenhouse gas emissions are reported in units of carbon dioxide equivalent (CO2e). Each greenhouse gas has a unique average atmospheric lifetime and heat-trapping potential. Greenhouse gas emissions are often calculated in terms of how much carbon dioxide (CO2) would be required to produce a similar warming effect. This is called the carbon dioxide equivalent value and is calculated by multiplying the amount of the gas by its associated global warming potential (GWP). For example, the GWP for methane is 21, so each tonne of methane that is emitted is considered to have a cumulative warming effect over the next 100 years equivalent to 21 tonnes of CO2.
GWP is based on a number of factors, including the heat-absorbing ability (known as radiative efficiency) of each gas relative to that of carbon dioxide, as well as the amount of each gas removed from the atmosphere over a given number of years (known as the decay rate) relative to that of carbon dioxide.
Under the Kyoto Protocol, the Conference of the Parties decided that the values of GWP calculated for the Intergovernmental Panel on Climate Change's (IPPC) Second Assessment Report were to be used to convert the various greenhouse gas emissions into comparable CO2 equivalents when the overall sources and sinks for the period 2008-2012 are being computed. For consistency, these GWP values will be used, even though the GWP values for some of the gases have subsequently been revised.

Approach to setting targets for existing facilities
The approach to determining the emission intensity targets for each sector is based on an improvement of 6% each year from 2007 to 2010.
This yields an initial required reduction of 18% from 2006 levels in 2010, the year the proposed greenhouse gas regulations would come into force. Every year thereafter, a 2% continuous improvement in emission intensity will be required. By 2015, therefore, a reduction in the emission intensity of 26% from 2006 levels would be mandated. This basic approach will be applied to existing facilities in each sector.
The 18% emission-intensity reduction calculation applies only to combustion and non-fixed process emissions. Regulatory release limits per unit of output for existing facilities would reflect this. Predefined fixed process emissions would have a 0% reduction in emission intensity from 2006 levels in 2010. Fixed process emissions are emissions that are tied to production and for which there is no alternative technology that will reduce them. The only way to reduce these emissions is to reduce production. Processes that are currently considered fixed may not be considered fixed in the future if technologies or processes are developed that could reduce or capture and store the emissions.
At the sector level, the share of fixed process emissions in total emissions varies. For each sector, the basic approach will be an 18% reduction from 2006 levels in 2010 with continuous improvement in emission intensity thereafter. Fixed process emissions will have to be determined on the basis of the characteristics of firms and sectors.
Approach to setting targets for new facilities
New facilities will be granted a three-year grace period before they have to meet an emission-intensity reduction target in order to provide sufficient time for the facilities to reach normal operating levels. After the third year, the initial greenhouse gas emission-intensity target will be based on cleaner fuel standards. New facilities will also be required to improve their emission intensity each year by 2%, as with existing facilities. New facilities are defined as those whose first year of operation is 2004 or later.
An example of fixed process emissions
Calcination in cement and lime production: Limestone, a raw material used to produce cement and lime, contains some carbon. When limestone is heated to extract the ingredients needed to produce cement and lime (a process known as calcination), carbon dioxide is formed and released into the atmosphere. There are no known techniques or practices to avoid the release of carbon dioxide when limestone is calcined.
An example of non-fixed process emissions
Anode effect in aluminum production: Anode effects are brief periods of instability and disequilibrium in the aluminum smelting process. These effects result in a chemical reaction that releases perfluorocarbons (PFCs), which are potent greenhouse gases. Anode effects can be controlled through modifications in the smelting process. Newer facilities have, in general, fewer emissions from anode effects, so this type of emission is not considered to be from a fixed process.
The three-year grace period means that no improvements are expected in the first three years of operation and no target will apply during those years. Targets begin to apply in the fourth year of operation, even if that year is before 2010. For example, a facility that began operation in 2005 will begin to accrue a target in 2008, based on its emission-intensity performance in 2007 and the application of a cleaner fuel standard.
A flexible approach to implementation will be taken in those special cases where the equipment used in a plant facilitates carbon capture and storage or another technology offering significant and imminent potential for emission reductions.
The approach described above is the one that will be applicable across the full range of industrial sectors. Specific sectoral issues will be considered in developing the regulations, but all resulting emission reductions must be equivalent to those resulting from the general approach.
The continuous improvement of 2% in a sector's emission intensity would be applied through 2020. As noted above, there will be a review of the regulatory framework, including targets, every five years. The first review would take place in 2012.
Firms will have several options to meet their legal obligations under the proposed greenhouse gas regulations. Ideally, firms will reduce their own emissions through abatement actions, such as energy efficiency measures, improved energy management systems, or deployment of carbon capture and storage or other emission-reducing technologies.
There will be limited access to other compliance mechanisms. First, firms could meet their compliance obligations through contributions to a technology fund. Second, they will have access to emissions trading, including inter-firm trading, emission-reduction credits from non-regulated activities, and qualified credits from the Kyoto Protocol's Clean Development Mechanism. Also, there will be a one-time recognition of early action for firms that took verified action between 1992 and 2006 to reduce their greenhouse gas emissions. Finally, linkages to North American emissions trading systems will be actively pursued. Over time, as the international carbon market becomes more fully developed and robust, and as emissions monitoring, verification, and reporting systems evolve further, the government will consider further international linkages.
Contributions to a climate change technology fund
Technological advancement and innovation are critical to achieving significant, long-term reductions in greenhouse gas emissions. New technologies, both under development and ready for deployment, provide a means to transform Canada's industrial production and thereby significantly reduce emissions.
Firms would be able to meet part of their regulatory obligations to reduce greenhouse gases by contributing to a technology fund. This fund would provide more than just a compliance mechanism for industry. It would act as an important means of promoting the development, deployment, and diffusion of technologies that reduce emissions of greenhouse gases across industry.
A third-party entity would be created to administer the fund. This would be an independent, not-for-profit entity administered by a board of directors composed of individuals originating from industry, federal and provincial governments, and other stakeholders. It would operate under a federal mandate.
Over the coming months, the process for determining the allocation of funding to projects and the legislative authority, governance, and administration of the fund will be further developed.
The design of the fund will respect two basic principles: no inter-regional transfer of wealth and no government control.
Before finalizing the structure of the fund, the government will work with provinces and territories, as well as sectors, to determine the appropriate disbursements of the funds, taking into consideration the development and deployment of technologies that would be used by sectors with facilities across the country and provincial initiatives that support the development of technology to reduce greenhouse gas emissions, and potentially, air pollutants as well.
Other funds that meet all necessary requirements could be certified to qualify as part of the regulatory framework. In particular, provincial funds that are consistent with the federal fund could be recognized as equivalent.
The fund would be used principally to fund investments that have a high likelihood of yielding greenhouse gas emission reductions in the near term. The primary focus would be on funding technology deployment and related infrastructure projects.
Carbon capture and storage is one of the most promising technologies for reducing greenhouse gas emissions associated with a broad array of industrial activities. The fund could support critical infrastructure for carbon capture and storage, including a pipeline in Alberta for CO2 transport. This could complement activities and priorities being defined through the Canada-Alberta ecoENERGY Carbon Capture and Storage Task Force.
The fund could also support an east-west electricity grid linking markets from Manitoba to Newfoundland.
As a way of meeting part of their regulatory obligations, firms could contribute to the fund at a rate of $15 per tonne of carbon dioxide equivalent from 2010 to 2012 and $20 per tonne in 2013. Thereafter, the rate would escalate yearly at the rate of growth of nominal GDP. This rate structure would be reviewed every five years as part of the general review of the regulatory system.
Contributions to the deployment and infrastructure component would be limited to 70% of the total regulatory obligation in 2010, falling to 65% in 2011, 60% in 2012, 55% in 2013, 50% in 2014, 40% in 2015, 10% in 2016, and 10% in 2017. The contribution limit will fall to 0% by 2018.
The government will also explore:
A smaller component of the fund, limited to an additional 5 Mt per year from 2010 to 2017, would help finance research and development projects aimed at supporting the creation of transformative technologies that are expected to achieve emission reductions in the medium to longer term.
Emissions trading will be an important component of the government's market-driven approach to reducing emissions of greenhouse gases. Well-designed emissions trading systems can reduce overall costs associated with regulatory compliance by allowing firms with high costs of emissions abatement to fund lower-cost emission-reduction projects at other firms. In addition, emissions trading systems create an economic incentive for companies to do better than their regulated targets and bring innovation to bear on the challenge of climate change.
The emissions trading system that will be part of the regulatory framework for greenhouse gases will have a number of components. Inter-firm trading, through which regulated firms may buy and sell emission credits among themselves, will be the central component. A domestic offset system will allow regulated firms to invest in verified emission reductions outside the regulated system. There will be no limit on firms' access to domestic emissions trading and offsets.
In addition, Canadian firms will have limited access to certain types of credits from the Kyoto Protocol's Clean Development Mechanism for compliance with the regulations.
Potential linkages with regulatory-based trading systems in the United States will be actively pursued. In particular, the government will examine the feasibility of linking with emissions trading systems such as the Western Regional Climate Action Initiative and the Regional Greenhouse Gas Initiative, as well as other systems, as they become established. Over time, as national and regional carbon markets become more mature and the markets become more global in nature, with robust emission reduction verification systems, Canadian firms will have increased access to international trading markets for purposes of compliance with Canadian regulations. Canadian firms will not, however, be allowed to use "hot air" credits, which do not represent real emission reductions, for compliance with Canadian regulations.
Recognizing the opportunity offered by emissions trading, Canada's exchanges have been positioning themselves to launch trading when the regulatory framework is finalized.
The Government of Canada will not purchase credits or otherwise participate in the carbon market.
The central component of the emissions trading system for greenhouse gases will be a baseline-and-credit system. For each firm, the baseline will be its emission-intensity target. Firms whose actual emission intensity in a given year is below their target will receive tradable credits equal to the difference between their target and their actual emission intensity, multiplied by their production in that year. These credits could be banked for use in future compliance years or sold to other parties through an emissions trading market established by the private sector.
The emissions trading system would also include domestic offset credits. Offsets are emission reductions that take place outside the domain of regulated activities.
Offset credits, which regulated firms could use towards their regulatory obligations, would be issued for verified reductions in greenhouse gas emissions that were incremental to what would have happened without the regulatory system or other government programs.
An offset credit would represent one tonne of verified greenhouse gas reduction or removal achieved by a given project, measured in carbon dioxide equivalent. The credit would be recognized in the regulations as tradable and could be used to meet the obligations of regulated facilities.
In a baseline-and-credit emissions trading system, a baseline is set. In this case, the baseline would be the emission-intensity target. Facilities that reduced emissions below their target would be allocated tradable credits that they could either bank for a future compliance obligation or sell to another facility. Facilities that emitted above their target would have to buy credits from other facilities or use their own banked credits to meet their regulatory obligation.
For example, suppose the emission-intensity target is 5.0 kt CO2e for every tonne of widgets produced. Suppose Facility A had an emission intensity of 4.5 kt/tonne and produced 1000 tonnes of widgets during the year. Then it would receive tradable credits from the government equal to the difference between the target (5.0) and its actual emission intensity (4.5) times its production in that year (1000). Or (5.0-4.5) x 1000 = 500 credits received.
Suppose Facility B had an emission intensity of 5.3 kt/tonne and produced 1200 tonnes of widgets. It would be required to remit to the government credits equal to the difference between its actual emission intensity (5.3) and the target times its production (1200), or (5.3-5.0) x 1200 = 360 credits owed. It could buy these credits from another facility or use credits that it had banked from a previous compliance period.
Offset credits would be issued for those activities where emission reductions could be accurately quantified and verified at a reasonable cost. Examples of possible offset project types include the capture of methane from landfill gas that is then used to generate electricity, energy-efficiency projects, and projects that store carbon in agricultural land. To lower the cost of participation, pre-approved quantification approaches would be provided and the aggregation of small projects would be encouraged.
The framework for the offset system would be built on the experience gained in three Canadian pilot initiatives and on project-based crediting systems in other countries. In addition, considerable work on the development of a framework has taken place in Canada, with the provinces and the private sector playing leading roles. Canada's private sector would play a major role in the offset system including verifying emission reductions achieved from eligible offset projects and providing infrastructure and services required for the trading of the credits.
The offset system would start prior to the entry into force of the regulations in order to provide adequate time for projects to generate emission reductions. Credits would be issued for these verified emission reductions. These credits could be sold to regulated entities to use for compliance purposes.
Clean Development Mechanism and other international linkages
Generally speaking, an emissions trading system with a broader scope will provide more opportunities for cost-effective emissions reductions. Over the past five years, a number of sub-national, national, and regional greenhouse gas emissions trading markets have been implemented or proposed for implementation in the near future. The most comprehensive of these is the European Union's Emissions Trading Scheme (EU ETS), which began with a pilot phase in 2005 and is moving to a more complete system starting in 2008. The experience of the EU ETS has provided valuable insights in developing Canada's regulatory system for greenhouse gases, and the government intends to continue discussions with the European Union on what Canada can learn from the European Union's experience with emissions trading.
Notwithstanding these developments, the international carbon market is still fragmented and in its infancy. As the global market develops and matures, there will be additional opportunities for Canadian firms to participate.
The government intends to start modestly, by allowing Canadian firms limited access to certain types of credits from the Kyoto Protocol's Clean Development Mechanism for the purpose of meeting their regulatory obligations.5 The government will determine which types of Clean Development Mechanism credits should be eligible for regulatory compliance in Canada.
Access to Clean Development Mechanism credits for compliance purposes under the regulations would be limited to 10% of each firm's total target.
A number of U.S. states are currently considering implementing regulatory regimes with emissions trading to reduce emissions of greenhouse gases. The Western Regional Climate Action Initiative intends to establish an emissions trading system for greenhouse gas emissions from industry in five western U.S. states. Starting in 2009, the Regional Greenhouse Gas Initiative will implement a regional emissions trading system in nine northeast and mid-Atlantic states that covers carbon dioxide emissions from power plants in the region. Several other greenhouse gas emissions trading initiatives have been proposed at the state and federal levels in the United States.
Canada will actively work with U.S. partners to explore opportunities for linking Canada's emissions trading system with regulatory-based emissions trading systems at the regional and state level, and with any that may be established at the federal level. Canada will also actively explore cooperation on emissions trading with Mexico.
The government will monitor the development of the international carbon market. As this market becomes more fully developed and robust, and emissions monitoring, verification, and reporting systems evolve further, the government will consider further linkages that could allow a broader range of international credits to become eligible for compliance with Canada's regulatory system. An essential condition is that any international credits used towards compliance with Canadian regulations represent real, verified emission reductions.
Credit for early action
Firms in a number of sectors have made efforts over the last decade to reduce emissions. There would be a one-time allocation of credits to those firms covered by the proposed regulations that took verified action to reduce their greenhouse gas emissions between 1992 and 2006. A maximum of 15 Mt would be allocated, with no more than 5 Mt to be used in any one year.
Firms would be invited to make a one-time application where they would submit evidence of changes in processes or facility improvements they undertook that resulted in incremental greenhouse gas emission reductions in the specified timeframe. There would be eligibility criteria to determine which emission reduction activities would be considered, and evidence of emission reductions would be audited.
Once all applications were received, the reserve would be allocated to all qualifying applicants on a pro rata basis. The maximum allocation for emission reductions would be one credit for one tonne of carbon dioxide equivalent reduction. If the total tonnage of emission reductions applied for were to exceed 15 Mt, the credits would be distributed to individual firms in proportion to their contribution to the total emission reduction achieved.
The availability of these different compliance mechanisms will provide industry with the access to emission reduction opportunities that they need to meet their regulatory obligations at a reasonable cost and will support the development of a functioning emissions trading market system. That said, the government recognizes that there may be concern about the level of market liquidity in the trading system, both at the start of the system and over time. The government will carefully monitor the evolution of the emissions trading system and other aspects of the compliance mechanisms in order to determine any modifications that might be required.
Fixed sectoral emission caps
The emission reduction targets for a given air pollutant will specify a maximum level of that pollutant that can be emitted from a given sector in a given year. These targets will represent national reductions from 2006 emission levels for each pollutant.
Fixed emission caps will be set for the following air pollutants: nitrogen oxides (NOx), sulphur oxides (SOx), volatile organic compounds (VOCs), and particulate matter (PM). Fixed emission caps for certain other air pollutants from specific sectors, such as benzene from natural gas production and processing, refineries, and iron and steel, and mercury from electricity generation and base metal smelting, will also be set. As more information becomes available and regulatory development is undertaken, the government will consider whether the regulations for specific sectors should include targets for other air pollutants not already identified (for example, benzene from oil sands).
Sectoral emission caps will be set for each air pollutant of concern in a given sector. Whether a cap is set for a specific pollutant in a given sector will depend on whether the pollutant is emitted in significant quantities from facilities in that sector. In some cases, caps will not be proposed for an air pollutant in a sector if measures to reduce another air pollutant will significantly reduce emissions of the first. How the sectoral caps will be allocated among facilities will be determined during the process of developing the detailed regulations.

The targets will come into effect as early as possible between 2012 and 2015 to give industry time to make the necessary investments in plant and equipment or processes.
The government will validate the benchmarked air pollutant targets over the next several months. The government will work with industry, provinces and territories, labour, and environmental and health groups during the validation process.
Regulatory, technology, and emission performance benchmarking
In the Notice of Intent, the government made a commitment to develop emission targets that "are at least as rigorous as those in the U.S. or other environmental performance-leading countries". To achieve this end, a benchmarking exercise was undertaken.
The exercise began by researching existing regulatory regimes; environmental performance; technology and operating practices; and the most stringent provincial operating permits in Canadian jurisdictions and other countries, such as the United States, Finland, Sweden, and Germany.
It also included taking into consideration factors underlying those regulatory regimes, such as the size and composition of the sectors; the concentration of facilities across the jurisdiction; and the availability and quality of feedstocks and other raw materials. From this exercise, environmentally-leading requirements were benchmarked by sector and by pollutant.
Concurrently, information was gathered on Canadian sectors. Where regulatory limits exist in other jurisdictions – for example, the pulp and paper and electricity sectors – actual Canadian regulatory limits and performance were compared with the regulated limits from leading jurisdictions.
In some sectors, regulatory limits are typically set through provincial certificates of approval or operating permits or licences for individual facilities, which can have processes and/or products that vary significantly from one facility to another – for example, petroleum refineries or chemical production facilities. In these sectors, the actual emission performance of Canadian facilities was compared with the reported or required performance in different jurisdictions, both in Canada and internationally. This involved deriving emission-intensity values and comparing the performance of similar Canadian and foreign facilities.
For other sectors – for example, aluminum smelting and iron and steel – emission performance both in Canada and abroad, as well as regulatory limits in other jurisdictions, was reviewed. In other cases, such as conventional upstream oil and gas, the approach was to benchmark against other facilities in the sector as a whole.
Finally, for the oil sands sector, which is unique to Canada, there are no comparable regulated sectoral emissions limits in other countries that would enable a comparison with other jurisdictions. In this case, sectoral targets were established using a multi-step approach. This included an evaluation of performance for similar activities, equipment, and processes at similar sources of emissions in other jurisdictions, such as heavy oil refineries; an examination of the potential for reductions using selected emission control technologies; and a comparison of emission-intensity performance of individual oil sands facilities within Canada.
In some sectors, analyses carried out in recent years were also taken into account when carrying out the benchmarking exercise. Work done jointly by government and industry was already under way to determine how to adapt benchmarked standards to Canadian circumstances in the pulp and paper sector through the Pulp and Paper Air Quality Forum, in the refining sector through the Canadian Council of Ministers of the Environment (CCME) National Framework for Petroleum Refinery Emission Reductions,6 and in the base metal smelting sector through the Base Metal Smelting Pollution Prevention Plan.7
The objective of the Pulp and Paper Air Quality Forum was to design a ten-year overall multi-faceted air emissions management regime for the pulp and paper industry that would include short-term air pollutant targets at a level that would ensure consistent requirements for all facilities. These proposed air pollutant targets were derived from benchmarking analyses that compared world leading international industry performance and the most stringent provincial limits. The approach of the Pulp and Paper Air Quality Forum ensures that a consistent level of available control technology exists among similar facilities and is in application elsewhere and that the overall economic impact of achieving these limits remains realistic. It also facilitates the establishment of equivalency agreements with provinces and territories.
The complexity of the existing regulatory system for petroleum refineries makes it difficult to define a single regulatory emission standard within Canada and other jurisdictions. For this sector, the approach used to determine the cap on emissions was based on the methodology developed through the CCME refinery framework, which was released on May 25, 2005. This framework established an approach to setting facility-level annual caps for a range of air pollutants based on benchmarking Canadian emission performance to comparable performance in the United States. Benchmarking was updated to reflect changes to the U.S. requirements.
A notice requiring the preparation of pollution prevention plans for base metal smelters and refineries and zinc plants was published in the Canada Gazette, Part I, on April 29, 2006. This Notice was the result of extensive work involving stakeholder consultations and five years of analyses of existing standards, performance, and sulphur capture efficiency of smelters around the world. The targets identified for consideration in the pollution prevention plans would be the basis of air pollutant caps for the base metal smelting sector.
Adjusting for Canada
In some sectors, regulatory limits or emission performance levels from leading jurisdictions were adapted to take into account characteristics specific to those sectors in Canada. Characteristics taken into account varied from sector to sector and included the financial situation of the sector; potential impacts on the economy; and the quality of feedstocks and other raw materials relative to the benchmarked jurisdiction.
The technical feasibility of meeting the most rigorous limits was also considered in establishing emission reduction target options. In some sectors, technically feasible options were evaluated to determine expected reductions in emissions and their cost in dollars per tonne.
Calculating national air pollutant caps
National emission caps were established by adding together the sectoral emission caps for each pollutant of concern, taking into account an allocation for growth of each sector by 2015.
There are two key considerations in setting benchmarks for the electricity generation sector. First, much of the transboundary air pollution that affects Canada's air quality comes from electricity generating plants in the United States. Second, the United States has new emission reduction targets that will further reduce air pollution from this sector between 2010 and 2018. Initial targets for nitrogen oxides (NOx) will come into force in 2009, while the targets for sulphur dioxide (SO2) will come into force in 2010. As well, more stringent targets for both pollutants will come into force in 2015. Canada and the United States currently have an emission reduction agreement in place. Implementing targets for Canadian facilities that are as stringent as those in the United States is a minimum objective if Canada is to enter into other emission reduction agreements with the United States. Setting Canadian requirements similar to those of the U.S. legislation, the Clean Air Interstate Rule (CAIR),* would make it easier to negotiate a cross-border emission cap-and-trade agreement with the United States. This would benefit Canadian electricity generators by increasing the size of the trading market.
The CAIR rule consists of reduction targets for emissions of sulphur dioxide and nitrogen oxides, as well as a cap-and-trade system that applies to all new and existing fossil fuel-fired electricity generators that have a capacity of greater than 25 megawatts.
It is not necessary for the Canadian requirements to be identical to those in the United States, but the main elements, including required emission reductions and rigour of monitoring, should be sufficiently comparable to permit the successful negotiation of a cross-border trading system.
* U.S. Environmental Protection Agency information on CAIR is available at www.epa.gov/airmarkets/progsregs/cair/index.html.
There would be a domestic cap-and-trade emissions trading system for SOx and NOx only. The method of allocating credits under the system, including the method by which new facilities would be accommodated within the overall cap, would be determined during the regulatory development process.
There would be separate credits and compliance assessments for SOx emissions and for NOx emissions. Firms would be required to submit credits each year equal to the emissions from their facilities for that year.
If a firm is in an area where the quality of the air does not meet national air quality objectives that have been set in advance by the government, restrictions will be placed on the use of credits from outside that area.
Under a cap-and-trade emissions trading system, a cap on total emissions from all facilities covered under the system is established. Credits equal to the cap are allocated to the facilities based on past emissions or by means of an auction. Each facility's allocation represents its individual emissions target. Facilities that emit above their individual limit have to buy surplus credits from another facility or use their own banked credits from a previous compliance period to meet their regulatory obligations. At the end of the compliance period, facilities must remit to the government sufficient credits equal to their actual emissions.
For example, suppose Facility A has been allocated 100 credits for its nitrogen oxide (NOx emissions. Suppose Facility B has been allocated 120 credits. Each credit represents one tonne of NOx.
At the end of the year, Facility A has actually emitted 108 tonnes of NOx. In order to be in compliance with its emissions target of 100 tonnes, Facility A is required to remit to the government 108 credits. It will remit its 100 initial credits and must either buy an additional 8 credits from the market or use 8 credits from any banked credits it might have.
Facility B actually emitted 116 tonnes of NOx. It will be required to remit to the government 116 credits from its allocation of 120 credits. It can either sell the remaining 4 credits to another facility or bank them for use in a future compliance period.
The feasibility of the use of offsets in combination with the cap-and-trade emissions trading systems for SOx and NOx will also be assessed.
The United States and Canada share cross-border air sheds and therefore have a shared responsibility for and interest in reducing air pollutants from all sources that contribute to air pollution. Addressing air pollution on only one side of the border does not make environmental or economic sense. The Canada-United States Air Quality Agreement was signed in 1991 to address transboundary acid rain. An annex to the agreement was added in 2000 to address ground-level ozone, a key component of smog. Under the agreement, Canada and the U.S. must reduce domestic emissions that flow into the other country and contribute to acid rain or ozone.
Canada and the U.S. recently agreed to start negotiations for an annex to the agreement to reduce the transboundary flow of particulate matter. Recent scientific analysis has shown that joint strategies are needed to address these pollutants. The annex will result in reductions in particulate matter as well as many of the chemicals that contribute to other air quality issues of concern, such as acid rain, regional haze, and visibility in the communities along the Canada-U.S. border.
Serious action by Canada to reduce its own emissions will make it easier to work jointly with the U.S. to reduce overall emissions. As part of its ongoing work with the U.S. to address transboundary air pollution, the government will expedite discussions with the U.S. on a cross-border SOx and NOx emissions trading system. Having caps in Canada and the U.S. of similar stringency would facilitate the development of cross-border trading. Such trading could provide additional flexibility for regulated sources by allowing the most cost-effective emission reductions to be made. A joint Canada-U.S. study, published in July, 2005,8 demonstrated the feasibility of cross-border trading of SO2 and NOx for the electricity sector.
CEPA 1999 has a number of compliance and penalty provisions. Failure by regulated entities to meet any of the requirements set out by CEPA 1999 or regulations made under it is an offence.
Enforcement officers verify compliance with the Act and its regulations. If a violation is confirmed, action is taken using one or more of the enforcement tools available under CEPA 1999, such as warnings, directions, tickets, orders of various types (including environmental protection compliance orders), injunction, or prosecution. Action taken in response to any failure to comply with regulatory requirements will be predictable and will correspond to the seriousness of the non-compliance.
When prosecution is undertaken, such offences may be prosecuted by either summary conviction or indictment. CEPA 1999 includes maximum fines of up to $1 million a day for each day an offence continues, imprisonment for up to three years, or both. Corporate directors and officers have a specific duty to take reasonable care to ensure that corporations comply with the Act, its regulations, and any orders of requirements issued by enforcement officers.
Health risks to Canadians from air pollution are associated with direct exposure to ambient levels of particulate matter and ozone,9 the main components of smog. The relationships between actual emissions, the levels of smog, and their effects on human health are complex, however. In addition, health science indicates that even at very low levels in the air, these pollutants have effects on human health. They also have negative impacts on the environment.
The government will set air quality objectives for particulate matter and ozone that will specify a target concentration for ambient air, based on an assessment of the health and environmental effects associated with exposure to these air pollutants in Canada. A decision on air quality objectives will be made after an analysis of benefits and risks over a range of concentrations in the air we breathe has been made.
This section provides the results of analysis and modelling to determine the health and environmental benefits and the economic impacts of the proposed regulations to reduce industrial air emissions. It directly addresses questions of central importance to Canadians.
The impacts of the proposed regulations were systematically traced through several models. All parts of the analysis start with an estimate of what would happen in the absence of the proposed regulations – the "business-as-usual" case. The proposed regulatory system and emission targets are then introduced in the model and assessed in terms of estimated reductions in emissions and changes in economic activity. Reductions in emissions are also translated, generally, into improvements in key air quality parameters. These improvements, in turn, have associated health and environmental benefits.
The modelling work to date has been complex, but provides reasonable, albeit preliminary, general results. Work to generate more refined estimates of the impacts is ongoing.
The economic impacts reflect an integrated assessment of the industrial greenhouse gas and air pollutant regulations. On the benefits side, the modelled impacts reflect improvements in air quality resulting from reduced air pollutant emissions only. It is clearly recognized, however, that climate change has wide-ranging global economic, environmental, and social impacts, with significant associated costs. These costs are not included in this analysis, but are an important consideration in the assessment of the cost-benefit impacts of the regulations.
What happens to air pollutants released to the atmosphere from human-related activities as well as natural emissions is simulated by Environment Canada's regional air quality modelling system, AURAMS. It describes the physical processes, such as transport, mixing, and deposition of the air pollutants, and the chemical transformations that air pollutants undergo in the atmosphere.
The model provides the concentrations and geographic distributions of primary air pollutants (those directly emitted to the atmosphere) and of secondary air pollutants (those formed chemically in the atmosphere from reactions involving primary pollutants) to which humans and ecosystems are exposed. The effects on human health and the environment from exposure to these air pollutants are then estimated by impact models. The results below are based on this modelling.
Figure G.1 provides an indication of the reductions in NOx emissions that are expected from the proposed regulatory system and targets, assuming they are all in place by 2015. Reductions in emissions are expected in the major urban centres and throughout the western provinces.

The predicted improvements in air quality resulting from the proposed reductions in air pollutant emissions are illustrated as percent reductions in annual levels of particulate matter (PM2.5) and in summertime ozone levels, assuming the regulations are implemented by the year 2015. Improvements in ozone levels are shown only for the summer as the formation of ozone increases with the amount of sunlight and, as a result, ozone is not an issue in the winter months. In addition, in order to highlight the impact of the proposed regulations on Canadian air quality, transboundary emissions of air pollutants from the United States were assumed to be constant in the model.
As shown in Figure G.2, preliminary results indicate that full implementation of the industrial regulations would decrease ozone levels by approximately 5% to 15% in a large portion of Alberta, Saskatchewan, Manitoba, and in localized areas in British Columbia, Ontario, Quebec, and the Maritimes, and by 1% to 5% in the rest of the country. Decreases in levels of ozone are also seen in neighbouring U.S. states.
As shown in Figure G.3, preliminary results predict annual reductions in PM2.5 of between 5% and 50% across a large portion of the country, with large reductions (15%-50%) in PM2.5 across the Prairie provinces, and reductions of 5% to 15% for southern Ontario.
Improvements in both ozone and PM2.5 levels are largest in western Canada, where marked reductions in emissions would result from the proposed regulations. Improvements in eastern Canada, although smaller in magnitude due to the large influence of long-range transport of air pollutants, provide benefits for the large populated areas that are more often affected by smog events.
In addition to improvements in ambient levels of both PM2.5 and ozone, Figure G.4 shows that reductions in acid deposition are predicted, particularly in areas where there are significant reductions in NOx and SOx emissions. This will result in a reduction in the size of the area receiving acid deposition levels that are in excess of what the environment, such as lakes or soils, can withstand without being adversely affected.

Health Canada's Air Quality Benefits Assessment Tool10 was used to estimate the human health benefits expected from changes in Canada's ambient air quality due to the proposed regulatory actions. It uses information on air quality, health effects of air pollutants, and the value of avoiding specific effects to calculate both the number of effects and the approximate value of these to Canadians.
Substantial health benefits are predicted from the proposed regulations since it is estimated they will achieve reductions in summertime ozone levels (about a 3% reduction) and a decrease in particulate matter (about 8%) in the year 2015. These two air pollutants are the major components of smog.
The total annual benefits in the year 2015 from the reduced risk of death and illness associated with these air quality improvements are estimated to be $6.4 billion.
The health benefits include reductions in premature mortality and various types of health effects (Table G.1). Most of the benefits are associated with the reduced risk of premature death, because of the large value placed on reduced mortality. Reductions in particulate matter account for the greatest share of the benefits because of the much greater effects on human health of long-term exposure to particulate matter relative to ozone. The total health impact is probably underestimated because only two air pollutants were considered and only some health outcomes could be quantified because of a lack of information on all outcomes.

Reductions in the emissions of harmful air pollutants and greenhouse gases would have many benefits for society, including improved environmental conditions that would provide direct benefits for Canadian ecosystems. In addition, reductions can also raise the economic productivity of specific sectors and increase the well-being of Canadians.
Some direct estimates were made of the environmental benefits from the proposed regulations. For example, ozone can hamper photosynthesis and increases the vulnerability of plants to pests and other stressors. The proposed regulations are predicted to reduce ozone levels and the associated stress to agricultural plants, resulting in an increase in production of $123 million for key agricultural crops in Canada. The total benefits to agriculture could be much higher, because the crops modelled only account for roughly 60% of the value of all crops and the impacts of soil acidification are not included.
Estimating costs of environmental damage is a relatively new area of research and is complex. Further work will be undertaken to estimate and place a value on the broader range of anticipated environmental impacts of the industrial air emission regulations. This work will build on the results of numerous studies that have estimated various costs of air pollution. For example:
For greenhouse gases, reductions by Canada alone will not significantly address global climate change. Nevertheless, Canada needs to do its share to control global greenhouse gas emissions in order to help address both the global effects and the more local threats to key sectors, resources, and infrastructure associated with climate change. These threats could include:
The previous section noted that the benefits associated with improved human and environmental health arising from the proposed regulations are on the order of $6.4 billion annually. These benefits need to be weighed against the possible economic costs that can be attributed to the regulatory regime in order to assess the overall impact on the Canadian economy and quality of life.
The economic costs of regulation are often difficult to measure, as they will depend on the reactions of a number of economic actors beyond the specific sectors directly affected. In the case of the proposed regulatory package, this would require not only that the direct impacts on production costs arising from industry compliance with emissions regulations be estimated, but also that the indirect impact of those costs on future investment decisions, demand and supply, and related consequences for other businesses and consumers be tracked. There are many points of uncertainty throughout this chain of actions and reactions.
Preliminary analysis performed by Environment Canada indicates that these costs will be small relative to total GDP, but not inconsequential.
From an aggregate perspective, the annual economic cost of meeting both the regulated greenhouse gas targets and the regulated air pollution targets should not exceed 0.5% of GDP in any given year up to 2020. The size of national economic costs anticipated under the regulations, combined with the inherent margin of error that must be applied to macroeconomic model results, makes it difficult to assess with any degree of certainty the impacts of the regulatory initiative at a provincial or sectoral level. However, the following general observations can be made:
While higher overall energy prices could result from the regulations, the extent to which prices will increase depends on a number of variables, including provincial regulatory policies, differences in capital turnover cycles between provinces' electricity generation units, and take-up of renewable energy incentives under recent federal and provincial programs. A noticeable increase in electricity prices is nevertheless possible. This increase could, in turn, result in some minor downward adjustments across most sectors of the economy over the long term (for example, around 2015 and later).
The proposed industrial regulations present Canadians with concrete action on key environmental challenges and meet their expectations for responsible and effective government measures to secure a cleaner and healthier environment for themselves and their children.
The economic costs associated with this initiative are real, but manageable. The benefits of this agenda are equally real, but in many respects, incalculable – cleaner communities and natural spaces, healthier children, fewer premature deaths, more sustainable natural resources, and, for the first time since signing the Kyoto Protocol, meaningful contributions by Canada to the global effort to control greenhouse gas emissions. The $6.4 billion a year in health benefits that will accrue under this initiative is significant on its own, but represents only a portion of the health and environmental gains that Canadians will receive.
The costs and benefits analysis demonstrates that the proposed regulatory package presents a responsible path forward. It will enable Canada to address climate change and air pollution without putting Canada's quality of life and economy at risk. It is equitable across regions and economic sectors. It respects the "polluter pays" principle. It puts in place, for the first time in Canada, a regulatory policy regime that can be fine-tuned to meet climate change and air quality objectives as we move forward. Most importantly, it provides Canadian business and citizens with the economic signals required to take into account the environmental consequences of daily decisions, whether it be choosing more energy-efficient appliances, or the construction of a new plant that uses renewable energy instead of fossil fuels.
Canadians have long demanded that their governments provide the leadership and tools necessary to enable them to better manage climate change and air quality as responsible citizens. Canada's New Government is responding to this and moving forward with a comprehensive plan.
The regulatory framework for air pollutants, including the timeframe for the entry into force of the regulations, will be finalized by fall 2007, after the government has validated the benchmarked air pollutant targets. Sector-specific regulations will be developed, leading to publication of the draft regulations in the Canada Gazette, Part I, starting in spring 2008 for the general provisions and those related to greenhouse gases. The regulations will be revised to incorporate the air pollutant provisions a few months later, following normal regulatory procedures.
The government intends to undertake a series of consultations over the coming months. The government will meet over the next several months with provinces and territories, each industry sector, labour, and environmental and health groups to discuss the implementation of the target structure for greenhouse gases and to validate the proposed air pollutant targets that have been determined through the benchmarking analysis, including the timeframe for their entry into force. In addition, the discussions will address the scope of the offset system, the administration of the technology fund, and the criteria for the credit for early action.
The government will work with each sector on the implementation of sector-specific regulations, including greenhouse gas provisions.
As part of the regulatory development process, a notice will be issued under Section 71 of CEPA 1999 to require industry sectors that will be covered by the proposed regulations to report to the government the 2006 data that will be used to set the emission reduction targets.
