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. ## Source and provenance - Official source: [Statistics Canada table 38-10-0097-01]() - Table title: Physical flow account for greenhouse gas emissions - Dataset identifier: 38100097 - Canonical human-readable answer: - Province and territory comparison: - Interpretation policy: this answer describes the selected observations; it does not infer causation. - Source acknowledgement: Adapted from Statistics Canada, Physical flow account for greenhouse gas emissions, 2025-12-11.
