The data explorer and the dataset are designed to assist in understanding the contributions of specific fuels and sectors to GHG emissions associated with energy for each country globally. The database includes estimates of total GHG emissions from energy and related indicators, covering CO2, CH4 and N2O emissions from fuel combustion, as well as fugitive emissions.

Energy accounts for more than three-quarters of total greenhouse gas (GHG) emissions globally. The IEA Greenhouse Gas Emissions from Energy provides a full analysis of historical country-level emissions stemming from energy use, and has become an essential tool for analysts and policy makers.

In 2022, the global CO2 emissions from fuel combustion increased by 1.3%, surpassing the levels preceding the COVID-19 pandemic. Fossil fuels continued to represent 81% of the total energy supply (TES) globally, with oil comprising nearly 30%, followed by coal (28%) and natural gas (23%). Global emissions from fuel combustion were dominated by coal (45%), followed by oil (33%) and natural gas (22%).

China and the United States together were responsible for 45% of the global fuel combustion emissions, followed by European Union, India, the Russian Federation and Japan. Explore the evolution of GHG emissions from fuel combustion across a range of countries in our interactive chart above. Compare the shares of different products in the total energy supply and their respective contributions to fuel combustion emissions in the interactive chart below.

Data

Greenhouse Gas Emissions from Energy

Annual time series of GHG emissions from energy, a major source of anthropogenic emissions. This database is updated twice a year. The April update includes all OECD and IEA family countries plus selected additional countries up to year-2. The final edition released in August includes data for all countries and regions up to year-2 and additional provisional data for OECD and selected countries up to year-1.
