Global Carbon Budget 2022
11 November 2022
A group of more than 100 researchers from more than 15 countries compiled and documented an annual global carbon budget covering sources and sinks. Coupling detailed observations with advanced models, they itemized emissions from fossil fuel combustion and land use change (mostly deforestation) offset by uptake in ocean, on land and into atmosphere. Emissions increased in the most recent year (2021) and most recent decade. Ocean and land continued to absorb carbon (serve as carbon sinks) while atmospheric concentrations continued to rise. They identify small imbalances due to imperfect knowledge of annual and decadal variability of sources and sinks. For the current year (2022) they project increased emissions and increased atmospheric concentrations to, effectively, levels now 50% higher than pre-industrial values. They present data and conclusions in the Copernicus open-access journal Earth System Science Data; interested readers will find descriptions of data and conclusions in https://essd.copernicus.org/articles/14/4811/2022/ and can access all original global and national data here: https://doi.org/10.18160/GCP-2022.
The annual update of the global carbon budget is produced by the Global Carbon Project and was started in 2006. This is the 11th update of the global carbon budget published by ESSD in the living data format:
