G20 power sector emissions by source 2023

Power sector emissions from the members that make up the Group of Twenty (G20) totaled 11.8 billion metric tons of carbon dioxide equivalent (GtCO₂e) in 2023, with coal-fired electricity responsible for almost three-quarters of this total. Combined, G20 countries accounted for roughly 83 percent of global power sector emissions in 2023.

Supplementary notes

Figures aim to include full lifecycle emissions including upstream methane, supply-chain and manufacturing emissions, and include all gases, converted into CO₂ equivalent over a 100 year timescale.

*Other fossil includes generation from oil and petroleum products, as well as manufactured gases and waste. **Other Renewables generation includes geothermal, tidal and wave generation.

The Group of Twenty (G20) comprises 19 countries (Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, United Kingdom and United States) and the European Union.
