Global GHG emissions by sector 1990-2023

The global power industry produced 15 billion metric tons of carbon dioxide equivalent (GtCO₂e) in 2023. This accounted for around 28 percent of global GHG emissions, and was almost double the emissions of the global transportation sector that year. The global power industry was consistently been the biggest overall contributor to global GHG emissions between 1990 and 2023.

Annual greenhouse gas (GHG) emissions worldwide from 1990 to 2023, by sector (in million metric tons of carbon dioxide equivalent)
