Global greenhouse gas emissions
Access PDF (479 KB)
This indicator highlights greenhouse gas (GHG) emissions caused by human activity around the world. Greenhouse gases remain in the atmosphere for periods ranging from a few years to thousands of years. As such, they have a worldwide impact, no matter where they were first emitted.
- Between 2005 and 2013, global GHG emissions increased by 18.3%. During that time, emissions from China increased by 61.5%.
- Canada's emissions in 2013 made up 1.6% of global GHG emissions.
Greenhouse gas emissions for the world and top 10 emitting countries and regions,Footnote  2005 and 2013
The column chart on the left shows global greenhouse gas emissions for 2005 and 2013. The bar chart on the right provides a breakdown of greenhouse gas emissions for the top 10 emitting countries or regions (China, United States, European Union, India, Russian Federation, Japan, Brazil, Indonesia, Canada and Mexico) for 2005 and 2013. Emissions in both charts are expressed in megatonnes of carbon dioxide equivalent.

Note: Greenhouse gas emissions for each country and region presented in this comparison were calculated by the World Resources Institute. For certain countries, including Canada, these values differ from the latest official estimate of greenhouse gas emissions submitted to the United Nations Framework Convention on Climate Change. Canada's emissions under this indicator also differ from the Greenhouse gas emissions indicator which is based on Canada's submission to the United Nations Framework Convention on Climate Change.

Canada's share of global emissions decreased since 2005. Like that of other developed countries, it is anticipated to continue to decline with the expected rapid increase in emissions from developing and emerging countries, particularly China, India, Brazil and Indonesia.
On December 12, 2015, Canada and 194 other countries reached the Paris Agreement, an ambitious and balanced agreement to fight climate change. This new agreement will strengthen the effort to limit the global average temperature rise to well below 2°C and pursue efforts to limit the increase to 1.5°C.
According to the Intergovernmental Panel on Climate Change, reaching this goal implies large-scale changes in energy systems and potentially land use across the world. In addition, the efforts and associated costs needed to reach this goal will vary between countries, with the distribution of costs across countries potentially being different from the distribution of the actions themselves.Footnote 
About the indicator
What does the indicator measure
The Global greenhouse gas emissions indicator reports global human emissions of greenhouse gases (GHGs) for 2005 and 2013. Emissions from energy and non-energy related sources are included in this indicator, while emissions from land use, land use change and forestry are excluded. The emissions of GHGs include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride.
Why is this indicator important
The indicator provides a global perspective on Canada's share of GHG emissions.
What are the related indicators
The Carbon dioxide emissions from a consumption perspective indicator provides a view of the impact of Canada's consumption of goods and services, regardless of where they are produced, on the levels of carbon dioxide released into the atmosphere.
The Greenhouse gas emissions indicators report trends in total anthropogenic (human-made) GHG emissions at the national level. Emissions are also presented per person and per unit gross domestic product, by province and territory, by economic sector and from large facilities.
