National Inventory Report 1990-2012: Greenhouse Gas Sources and Sinks in Canada
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.
Totals reflect net emissions (the sum of all sources minus the sum of all sinks). Emissions from the Memo Items source category, which covers fuel combustion from international transport activities, are not included in inventory totals.
Emission metrics by fuel type and for specific chemicals within the HFC and PFC pollutant families are not included in the portal, but may be added in the future.
