Global CO2 emissions for 2023 increased by only 0.1% relative to 2022 (following increases of 5.4% and 1.9% in 2021 and 2022, respectively), reaching 35.8 Gt CO2. These 2023 emissions consumed 10–66.7% of the remaining carbon budget to limit warming to 1.5°C, suggesting permissible emissions could be depleted within 0.5–6 years (67% likelihood).
Key points
-
Data from the Carbon Monitor indicate 35.8 Gt CO2 were emitted globally in 2023.
-
Although the trend is upwards, the pace of growth has been slowing, suggesting global emissions might have plateaued.
-
India overtook the EU as the third highest emitter globally.
