Canada's Greenhouse Gas Inventory
As a signatory to the United Nations Framework Convention on Climate Change (UNFCCC), Canada is obligated to prepare and submit an annual national greenhouse gas (GHG) inventory covering anthropogenic emissions by sources and removals by sinks. Environment Canada is responsible for preparing Canada’s official national inventory with input from numerous experts and scientists across Canada. The National Inventory Report (NIR) contains Canada’s annual greenhouse gas emission estimates dating back to 1990.
The NIR, along with the Common Reporting Format (CRF) tables, comprise Canada’s inventory submission to the UNFCCC and are prepared in accordance with the UNFCCC Reporting Guidelines on annual inventories, Decision 24/CP.19.
