![]() The Global Carbon Project and its partners provide annual scientific assessments of CO 2 emissions from human activities and their redistribution in the atmosphere, ocean and terrestrial biosphere in a changing climate. ![]() See the data description paper, Global Carbon Budget 2021, by Friedlingstein et al for information about the data reporting methods and uncertainties. Scientists also report an imbalance of 3% (-1.0 GtCO 2/yr) between the estimates for global sources and sinks. The global carbon budget numbers above are the best available scientific determinations at the time they were reported. This accumulation has been observed as continued increases in CO 2 concentrations in the atmosphere. The remainder were added to the CO 2 which is accumulating in the atmosphere. A small part of the fossil fuel total is from new cement usage.įrom 2011 to 2020, about 55% of global emissions were absorbed by the terrestrial biosphere and oceans. Most human-caused emissions of CO 2 into the atmosphere are from burning fossil fuels that had long been stored in the crust of the Earth. Global CO 2 emissions from human activity Data were published November 5, 2021, in Global Carbon Budget 2021 by the Global Carbon Project. Numbers present the yearly average for one decade (2011 to 2020). ![]() The data below summarize all human-caused sources of CO 2 emissions and global sinks (where the CO 2 goes). (3) Global fossil fuel emissions for 2021 are projected (2) Fossil fuel emissions exclude sinks from cement carbonation *NOTES: (1) Values for GtCO 2 in the above table were calculated by CO2.Earth by multiplying carbon emissions in the linked Excel data file by 3.664, and by adding emissions from fossil fuels and land-use change to determine total emissions Source data from Global Carbon Project 2021 (via ICOS):ĭata supplement + global data (.xlsx) + national emissions (.xlsx) The 2021 growth of 1.6 GtCO 2 is similar to the growth observed in 2010 following the global financial crisis of 2008-2009 (1.7 GtCO 2 5.5% above 2009 levels).Ģ021 Global Carbon Budget (November 2021) Global emissions in 2021 remain about 0.8% below their level in 2019. The record decrease in 2020 emissions was 1.9 billion tonnes of CO 2 (GtCO 2), from 36.7 GtCO 2 in 2019 to 34.8 GtCO 2 in 2020. Emissions from coal and gas use are set to grow more in 2021 than they fell in 2020, but emissions from oil use remain below 2019 levels. ![]() Global fossil CO 2 emissions in 2021 are set to rebound close to their pre-COVID levels after an unprecedented drop in 2020. ![]() (The 2021 growth of 1.6 GtCO 2 is similar to the growth observed in 2010 following the global financial crisis of 2008-2009: 1.7 GtCO 2 or 5.5% above 2009 levels.)
