The power sector produced 14.9 billion metric tons of carbon dioxide equivalent (GtCO₂e) worldwide in 2023, making it the largest source of global GHG emissions. Road transportation and industry followed, with both these segments emitting roughly six GtCO₂e. Together, these three subsectors were responsible for half the world's total GHG emissions in 2023.
