- 2021 total anthropogenic CO₂ emission (including the cement carbonation sink) of 10.9 ± 0.8 GtC/year (40.0 ± 2.9 GtCO₂)
- for 2021, fossil emissions increased by 5.1 % relative to 2020 to 10.1 ± 0.5 GtC/year (9.9 ± 0.5 GtC/year when the cement carbonation sink is included)
- 2021 global atmospheric CO₂ concentration: 414.71 ± 0.1 ppm
- remaining carbon budget for a 50 % likelihood to limit global warming to 1.5, 1.7, and 2°C has reduced to 105 GtC (380 GtCO₂), 200 GtC (730 GtCO₂), and 335 GtC (1230 GtCO₂)
The Global Carbon Budget 2022 is a collaborative effort of the global carbon cycle science community coordinated by the Global Carbon Project.
