Electricity generation emissions by country 2022

China was the largest contributor to global power sector emissions in 2022, producing 4.7 billion metric tons of carbon dioxide equivalent (GtCO₂e) from electricity generation. This was roughly three times more than the power sector emissions in the U.S. - the second-largest emitter within the sector. While China's power sector emissions are far higher than the U.S., the country's per capita emissions from electricity generation are lower.

Supplementary notes

*Emissions data for Saudi Arabia was unavailable for 2022. Saudi Arabia's 2021 emissions data has been included in this statistic for reference due to being among the top 10 power sector emitters that year.

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.
