Fossil CO2 emissions growth: 2019–2021

Global emissions in 2020 dropped across all categories.�In 2021 coal and natural gas have more than recovered this loss, while oil still lags with from subdued transportation.

Fossil CO2 Emissions by source

Emissions by category from 2000 to 2020, with growth rates indicated for the more recent period of 2015 to 2020�Coal use has declined since 2014, and both coal and oil declined sharply in the pandemic year 2020

Fossil CO2 Emissions in China

Annual emissions in China are expected to reach another record high in 2021, with substantial industrial growth

29 of 86

Fossil CO2 Emissions in USA

The USA’s emissions from coal are expected to bounce back in 2021, partly as a result of supply constraints on natural gas. Emissions from oil do not return to 2019’s level.

30 of 86

Fossil CO2 Emissions in the European Union

In the first half of 2021 EU coal power generation was strong due partly to very low generation from wind power, but the 2021 total is expected to remain below 2019’s level and continue to decline.

31 of 86

Fossil CO2 Emissions in India

India’s emissions are expected to jump sharply in 2021, returning to a strongly growing trend driven largely by use of coal in power generation.

32 of 86

Fossil CO2 Emissions in Rest of World

In the Rest of the World, emissions from coal and natural gas are expected to recover most of their losses in 2020.�Oil, which here includes internationship transport, remains subdued.

The Rest of the World is the global total less China, US, EU, and India. It also includes international aviation and maritime shipping.�Source: Friedlingstein et al 2021; Global Carbon Project 2021

Global carbon budget

Carbon emissions are partitioned among the atmosphere and carbon sinks on land and in the ocean�The “imbalance” between total emissions and total sinks is an active area of research

47 of 86

Changes in the budget over time

The sinks have continued to grow with increasing emissions, but climate change will affect�carbon cycle processes in a way that will exacerbate the increase of CO2 in the atmosphere

The budget imbalance is the total emissions minus the estimated growth in the atmosphere, land and ocean.

It reflects the limits of our understanding of the carbon cycle.

Airborne Fraction

The airborne fraction is the proportion of the total annual CO2 emissions that remains in the atmosphere.

The rest of CO2 emissions are removed by the land and ocean sinks.�Around 45% of CO2 emissions remain in the atmosphere despite sustained growth in CO2 emissions.

51 of 86

Ocean sink

The ocean carbon sink, estimated by Global Ocean Biogeochemical Models and observation-based data products, �continues to increase 10.2 ± 1.5 GtCO2/yr for 2011–2020 and 11.0 ± 1.5 GtCO2/yr in 2020

52 of 86

Terrestrial sink

The land carbon sink, estimated by Dynamic Global Vegetation Models, was 11.2 ± 2.2 GtCO2/yr �during 2011–2020 and 10.7 ± 3.6 GtCO2/yr in 2020.�Total CO2 fluxes on land (including land-use change) are also constrained by atmospheric inversions.

53 of 86

Land and ocean sinks — Effects of CO2 vs climate change

Process models suggest that increasing atmospheric CO2 drives the land and ocean sinks while climate change reduces the carbon sinks; the climate effect is largest in tropical and semi-arid land ecosystems.�Globally during the 2011-2020 decade, climate change reduced the land sink by ~15% and the ocean sink by ~5%
