## How to read this measure

This is the physical-flow account, not the ECCC National Inventory Report or a consumption footprint. Methane and nitrous oxide use global warming potentials of 28 and 265. 2009–2022 data were revised in December 2025. Totals may differ from component sums due to rounding.

## How this answer was calculated

The headline compares the first and last observations shown. Absolute change is the last source value minus the first; relative change is (last ÷ first − 1) × 100. Intermediate observations remain visible in the chart and exact values. This is descriptive and does not identify causes.
