The global carbon budget: the numbers that tell the truth on climate action


Last year, global carbon emission trends rebounded to their pre-COVID-19 levels, after an unprecedented decline of 5.4% in 2020 due to international lockdowns. Despite calls for global climate action, emissions from coal and gas projected to grow more in 2021 than they fell the previous year.

To keep the world on the pathway to 1.5°C, it was estimated that a "carbon budget" of just 11 years (at 2021 emissions levels) remains.

And, as leaders met at COP26, the scientists behind these projections – via the Global Carbon Budget (GCB) – could not rule out a further rise in emissions in 2022.

Pressure is mounting for governments, investors, and corporations alike to urgently act on their Nationally Determined Contributions and net-zero goals. Additionally, the war in Ukraine has brought to the fore questions of fossil fuel dependency and the need to accelerate the energy transition, now.

New Global Carbon Budget projections – being released at COP27, Egypt – will showcase not only how much progress has been made in the past year to reduce CO2 emissions, but also how many years of "carbon budget" we have left.

Join us to learn about the Global Carbon Budget, last year's carbon emissions trends, and the remaining total carbon budget if we are to stay on the 1.5°C pathway.The webinar will be led by the University of Exeter Professor and lead author of the Global Carbon Budget, Pierre Friedlingstein.
