Fossil fuel emissions proceed to rise


In keeping with the Global Carbon Project research team, global carbon dioxide emissions are at record levels in 2022 – with no signs of the decline that’s urgently needed to limit warming to 1.5 ° C.

If current emission levels proceed, there may be now a 50% probability that a 1.5 ° C global warming will likely be exceeded in nine years.

The brand new report predicts that total global CO2 emissions will reach 40.6 billion tonnes (GtCO2) in 2022. That is driven by CO2 emissions from fossil fuels, that are projected to extend by 1.0% in comparison with 2021, reaching 36.6 GtCO2 – barely above pre-2019 COVID-19 levels. Emissions from land use change akin to deforestation are projected to be 3.9 GtCO2 in 2022.


Projected emissions from coal and oil are above 2021 levels, with oil accounting for the biggest share of total emissions growth. The rise in oil emissions can largely be explained by the delayed rebound of international aviation following the COVID-19 pandemic restrictions.

The situation for major issuers in 2022 is mixed: emissions are projected to say no in China (0.9%) and the EU (0.8%) and increase within the US (1.5%) and India (6%). with a rise of 1.7%, the remaining of the world combined.

The remaining carbon budget for a 50% probability of limiting global warming to 1.5 ° C has decreased to 380 GtCO2 (exceeded after nine years if emissions remain at 2022) and 1,230 GtCO2 to 2 ° C (30 years in emissions in 2022).

Achieving zero CO2 emissions by 2050 would now require a decrease of around 1.4 GtCO2 annually, comparable to the observed reduction in emissions in 2020 as a consequence of the lock-in of COVID-19, highlighting the dimensions of the motion required.

Lands and oceans that absorb and store carbon dioxide still absorb around half of CO2 emissions. CO2 sinks within the oceans and on land proceed to grow in response to increases in CO2 within the atmosphere, although climate change has limited this increase by around 4% (ocean sinks) and 17% (terrestrial sinks) between 2012 and 2021.


This yr’s carbon budget shows that the expansion rate of fossil fuel emissions has slowed over the long run. Within the 2000s, average growth peaked at + 3% each year, while growth within the last decade was around + 0.5% each year.

A research team – including the University of Exeter, the University of East Anglia (UEA), CICERO and Ludwig-Maximilian-University Munich – welcomed the slowdown, but said it was “removed from reducing the emissions we want.”

The findings come as world leaders meet at COP27 in Egypt to debate the climate crisis.

“This yr we see one other rise in global CO2 emissions from fossil fuels when we want a rapid decline,” said Professor Pierre Friedlingstein of the Global Systems Institute in Exeter, who led the study.
