Electricity and heat production emitted 14.4 billion metric tons of carbon dioxide equivalent (GtCO₂e) worldwide in 2021, making it the largest source of global net anthropogenic greenhouse gas emissions. Road transportation followed with roughly six GtCO₂e. These two subsectors were responsible for more than one-third of global GHG emissions in 2021.
