Global GHG emissions by sector 1990-2022

The global power industry has consistently been the biggest overall contributor to global greenhouse gas emissions for the more than 30 years. In 2022, the power industry produced 15 GtCO₂e, which was almost double the emissions of the global transportation sector.
