Global methane emissions by sector reported to the UNFCCC and estimates from the IEA, 2021

Notes

UNFCCC submissions from the Greenhouse Gas Data Interface for the latest year available. Reference estimates for energy are the Methane Tracker estimates for 2021. For non-energy sector emissions, these are taken as an average of estimates available for 2018 or 2019 from UNFCCC, CAIT, EDGAR and CEDS (see Methodology for further information).
