Methane (CH4) is responsible for approximately 30% of the rise in global temperatures since the Industrial Revolution, even though its share of global GHG emissions is not that large at about 18%.

Globally, methane emissions (excluding LULUCF*) were basically flat at about 6,800 Mt CO2eq from 19990-2001. They have since steadily increased to almost 9,000 Mt CO2eq in 2022 with a dip in 2020 from the impact of the Covid pandemic.

China is the largest emitter of CH4 with over 1,300 Mt CO2eq emissions in 2022, about 15% of the total. They are followed by the US at 800 Mt CO2eq (9%), India at over 700 Mt CO2eq (8%), Russia at 600 Mt CO2eq (7%), and Brazil at almost 550 Mt CO2eq (6%).

Combined, these top 5 methane emitters represent almost 50% of global methane emissions.

Canada’s methane emissions are less than 100 Mt CO2eq.
