Global greenhouse gas (GHG) emissions increased 1.7 percent in 2022 to reach a high of 53.8 billion metric tons of carbon dioxide equivalent (GtCO₂e). Since 1990, global GHG emissions have increased by more than 60 percent. CO₂ accounts for roughly three quarters of greenhouse gas emissions, and is the main driver of climate change.
