Are Canada's greenhouse gas emissions falling?
Canada's greenhouse gas emissions fell to 8,321.2 megatonnes CO2 equivalent in September 2025, down from 9,465.5 in the previous period.
What this measures
This indicator tracks Canada's total greenhouse gas (GHG) emissions, measured in megatonnes of carbon dioxide equivalent. It matters because reducing emissions is key to meeting Canada's climate targets and limiting global warming.
Annual GHG Emissions Trend
Canada's GHG emissions have fluctuated since 2021, peaking at 9,855.3 megatonnes in 2023 before declining to 8,897.3 in 2025. The drop from 2023 to 2024 (-362.2 Mt) suggests progress, but the 2025 figure remains above 2021 levels (-6893.9 Mt).
