Emission Inventories & Forecasts

Every five years we compile an "emission inventory" that describes the types and amounts of contaminants released into the air by different sources. We also compile an emission backcast and forecast, which helps us to track how emissions have changed over the past 20 years and how we expect them to change in the future.

Thousands of sources release air contaminants everyday. Emission sources range in size from your vehicle and your household furnace, to small businesses, marine vessels and large-scale industrial operations.

To keep track of these emissions, Metro Vancouver compiles an "emission inventory" every five years. The inventory describes the types and amounts of contaminants released into the air by different types of sources. We also compile an emission backcast and forecast, which helps us to track how emissions have changed over the past 20 years and how we expect them to change in the future.
