Line chart showing remaining carbon budget for global CO2 emissions pathways, by temperature target. The carbon budget will run out by 2037 for a 1.5°C target, by 2053 for a 1.7°C target and by 2079 for a 2.0°C target. There is 275 GT of CO2 remaining the carbon budget for the 1.5°C target, 625 Gt CO2 for the 1.7°C target, and 1150 Gt CO2 for the 2°C target.
