Global carbon emissions in 2021 are set to rebound close to pre-Covid levels while China and India are forecast to send more carbon dioxide into the atmosphere this year than in 2019, according to the Global Carbon Project (GCP).

Fossil-fuel carbon emissions decreased by 5.4% in 2020 amid widespread coronavirus lockdowns, but GCP’s new study released Thursday forecast a mean increase of 4.9% this year, totalling 36.4 billion tonnes.

Emissions of both gas and coal are set to increase more in 2021 than they declined last year, although emissions from oil use currently remain below 2019 levels.
