Energy Agency: CO2 Emissions Rise in 2022, But More Slowly

October 19, 2022

BERLIN — The International Energy Agency said Wednesday that it expects carbon emissions from the burning of fossil fuels to rise again this year, but by much less than in 2021 due to the growth in renewable power and electric cars.

Last year saw a strong rebound in carbon dioxide emissions — the main greenhouse gas responsible for global warming — after the global economic downturn caused by the coronavirus pandemic in 2020.

The Paris-based IEA said CO2 emissions from fossil fuels are on course to rise by almost 1% in 2022 compared to the previous year. That’s nearly 300 million metric tons of CO2 more than in 2021, when the burning of gas, oil and coal released about 33.5 billion tons of CO2.

“This year’s increase is driven by power generation and by the aviation sector, as air travel rebounds from pandemic lows,” the agency said.

While coal emissions grew as countries which previously imported natural gas from Russia scrambled for other energy sources, this didn’t outweigh the expansion of solar and wind power.

“The rise in global CO2 emissions this year would be much larger – more than tripling to reach close to 1 billion tonnes – were it not for the major deployments of renewable energy technologies and electric vehicles around the world,” it said.

Emissions of carbon dioxide and other greenhouse gases need to decline drastically in the coming decades to keep global temperatures from rising beyond 1.5 degrees Celsius (2.7 Fahrenheit), the ambitious threshold agreed in the 2015 Paris climate pact. Scientists say there is little room left for maneuver because temperatures have already risen by about 1.2 Celsius (2.2 Fahrenheit) compared to pre-industrial times.
