Changelog:

2023 total anthropogenic CO₂ emission (including the cement carbonation sink) of 11.1 ± 0.9 GtC/year (40.6 ± 3.2 GtCO₂/year)
2023 fossil CO₂ emissions increased by 1.3% relative to 2022 to 10.3 ± 0.5 GtC/year (10.1 ± 0.5 GtC/year when the cement carbonation sink is included)
2023 global atmospheric CO₂ concentration: 419.3 ± 0.1 ppm
remaining carbon budget for a 50 % likelihood to limit global warming to 1.5, 1.7, and 2 °C has been reduced to 65 GtC (235 GtCO₂), 160 GtC (585 GtCO₂), and 305 GtC (1110 GtCO₂),
