Canada’s Air Pollutant Emissions Inventory Report 2024: annex 2

In-House Estimation Methodologies

The in-house emissions estimation methodologies and emission models used in Canada are generally based on those developed by the United States Environmental Protection Agency (U.S. EPA) and adapted to use Canadian data, thereby accounting for differences in climate, fuels, technologies and practices. Methods used in Canada’s Air Pollutant Emissions Inventory (APEI) are therefore generally consistent with those used in the United States or those recommended in the EMEP/EEA Air Pollutant Emission Inventory Guidebook (EEA, 2019).

Table A2–1 through Table A2–11 summarize, for each source category, the in-house estimation methodologies for the entire time series. For each source category, these tables provide:

• a short description of the emission sources and pollutants covered;
• the general inventory methodology approach, activity data and emission factors; and
• references.
