Abstract
Global CO2 emissions for 2022 increased by 1.5% relative to 2021 (+7.9% and +2.0% relative to 2020 and 2019, respectively), reaching 36.1 GtCO2. These 2022 emissions consumed 13%-36% of the remaining carbon budget to limit warming to 1.5°C, suggesting permissible emissions could be depleted within 2-7 years (67% likelihood).
