Global Carbon Budget 2021

The annual update of the global carbon budget and trends to achieve net zero

Launched in 2006 and produced by 94 people from 70 organisations in 18 countries, the Global Carbon Budget is the critical annual update which reveals the latest trends in global carbon emissions and the ramifications for reaching the global climate goals.

Professor Pierre Friedlingstein at the University of Exeter’s Global Systems Institute and Professor Corinne Le Quéré, Royal Society Research Professor at University of East Anglia’s School of Environmental Sciences have led the 2021 Global Carbon Budget Report and alongside a host of other research institutions provide the data and analysis on the major emitters including China, USA, EU27, India and the rest of the world.

The 2021 report – the 16^th annual Global Carbon Budget – also provides vital new information on rates of deforestation, and the continued high global use of coal, oil, and gas to fuel our economies.

"The rebound in global fossil CO2 emissions in 2021 reflects a return towards the pre-Covid fossil-based economy. Investments in the green economy in post-Covid recovery plans of some countries have been insufficient so far, on their own, to avoid a substantial return close to pre-Covid emissions."

The Global Carbon Budget 2021 has been possible thanks to the contributions of hundreds of people involved in observational networks, modelling, and synthesis efforts.

Thank you to the institutions and agencies that provide support for individuals and funding that enable the collaborative effort of bringing all components together in the carbon budget effort.
