Figures are based on fugitive and exhaust emissions from flaring, venting combustion, and non-combustion related processes during oil and gas exploration, production, processing, and transport of crude oil, gas, and liquefied natural gas.
Oil and gas field- and basin-level carbon dioxide and methane emissions are estimated with the Oil Production Greenhouse Gas Emissions Estimator (OPGEE) Model. Inputs include a number of oil and gas field characteristics, including satellite-derived flaring volumes. Field-level estimates are summed and scaled to country-level on an annual basis.
Figures account for greenhouse gas emissions based on their 100-year global warming potential (GWP).

Global GHG emissions from oil and gas production and transport 2015-2023
Global oil and gas production and transport generated **** billion metric tons of carbon dioxide equivalent (GtCO₂e) in 2023 – a year-on-year increase of *** percent. Oil and gas production and transport is estimated to have produced around ** GtCO₂e worldwide between 2015 and 2023.
