Methane emissions and intensities of the top 10 emitting countries, 2025

Sources

IEA estimates based on measured, satellite, and inferred data (see Documentation for further information).

Notes

USA= United States. Upstream methane intensity = upstream fossil fuel methane emissions divided by total fuel supply in energy terms, assuming that methane has an energy density of 55 megajoules per kilogram (MJ/kg). Measured data availability varies across countries: China (limited), United States (moderate), Russia (none), Iran (limited), Turkmenistan (limited), India (limited), Venezuela (none), Indonesia (none), Kazakhstan (limited), Iraq (limited).
