Global Greenhouse Gas Emissions: 1990-2022 and Preliminary 2023 Estimates
We estimate that global GHG emissions rose in 2023 by 1.2% over the previous year, reaching 51.8 gigatons of CO2-equivalent on net. This follows a 1.0% increase in 2022 as countries recovered from the COVID-19 pandemic disruptions of 2020.
