Notes

UNFCCC = United Nations Framework Convention on Climate Change, OGMP 2.0 = Oil & Gas Methane Partnership 2.0, IOGP = International Association of Oil and Gas Producers. IEA estimates are for 2023, other estimates are for the latest year available. Emissions from company reporting are scaled to global level based on the share of production of reporting companies and assuming non reporting companies have the same average emissions intensity.
