Key highlights of the report:
- Global CO2 emissions from fossil fuels and industry have increased every decade from an average of 11.4 GtCO2 in the 1960s to an average of 34.7±2 yr-
- Regional fossil fuel emissions:
- In 2018, global CO2 emissions were dominated by emissions from China (28%), the USA (15%), the EU (28-member states; 9%) and India (7%).
- Growth rates of these countries from 2017 to 2018 were +2.3% for China, +2.8% for the USA, -2.1% for the EU28, and +8.0% for India.
- Net CO2 emissions from deforestation and other land-use change were5±2.7 GtCO2 on average during 2009-2018, accounting for about 14% of all emissions from human activity (fossil fuel, industry, land use change).
- CO2 removals by natural sinks: Of the total emissions from human activities during the period 2009-2018, about 45% accumulated in the atmosphere, 23% in the ocean and 29% on land.
- Atmospheric CO2 concentration in 2019 are 47% above pre-industrial levels.
- The cumulative carbon emissions are the sum of the total CO2 emitted during a given period of time. Total cumulative emissions from 1850 to 2019 were 1649 GtCO2 from fossil fuels and industry, and 751 GtCO2 from land use change.
