Changelog:
- 2020 total anthropogenic CO₂ emissions: 10.2 ± 0.8 GtC/year (37.4 ± 2.9 GtCO₂/year)
- in 2020 fossil emissions declined by 5.4% relative to 2019, reduced to 9.5 ± 0.5 GtC/year (34.8 ± 1.8 GtCO₂/year) with cement carbonation excluded
- 2020 global atmospheric CO₂ concentration: 412.45 ± 0.1 ppm
- compared to earlier estimates revised land-use change emissions show decrease in last decade
Cement Carbonation sink (positive values represent a flux from the atmosphere to the land)
All values in million tonnes of carbon per year (MtC/yr). For values in million tonnes of CO₂ per
year, multiply the values below by 3.664
1MtC = 1 million tonne of carbon = 3.664 million tonnes of CO₂
Methods: Full details of the method are described in Friedlingstein et al (2021).
1MtC = 1 million tonne of carbon = 3.664 million tonnes of CO₂
