Data
Share of each gas in world greenhouse gas emissions, 2025 (EDGAR)
How much of the world's greenhouse gas emissions in 2025 was fossil carbon dioxide, methane, nitrous oxide and fluorinated gases, as stated in the EDGAR 2026 report, measured in carbon dioxide equivalent. Land use, land-use change and forestry are not included. 2025 is a Fast-Track estimate.
