Global carbon emissions in 2022 remain at record levels — with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team. If current emissions levels persist, there is now a 50% chance that global warming of 1.5°C will be exceeded in nine years. The new report projects total global CO2 emissions of 40.6 billion tonnes (GtCO2) in 2022. This is fuelled by fossil CO2 emissions which are projected to rise 1.0% compared to 2021, reaching 36.6 GtCO2 — slightly above the 2019 pre-COVID-19 levels[1]. Emissions from land-use change (such as deforestation) are projected to be 3.9 GtCO2 in 2022.
Projected emissions from coal and oil are above their 2021 levels, with oil being the largest contributor to total emissions growth. The growth in oil emissions can be largely explained by the delayed rebound of international aviation following COVID-19 pandemic restrictions.
The 2022 picture among major emitters is mixed: emissions are projected to fall in China (0.9%) and the EU (0.8%), and increase in the USA (1.5%) and India (6%), with a 1.7% rise
