【Report】IEA “CO2 Emissions in 2022” Report: Global CO2 emissions hit new record in 2022
The International Energy Agency (IEA) published a report analyzing emissions of greenhouse gas from energy production in 2022. The report covers CO2 emissions from all energy combustion and industrial processes, and additionally includes information on methane (CH4) and nitrous oxide (N2O) emissions in 2022.
◇ Global energy-related CO2 emissions grew in 2022, reaching a new high record – as the growth of solar, wind, EVs, heat pumps and energy efficiency helped limit the impacts of increased use of coal and oil amid the global energy crisis, it was less than initially feared.
- Global energy-related CO2 emissions grew in 2022 by 0.9%, or 321 million tonnes, reaching a new high of more than 36.8 billion tons.
- Amid a wave of gas-to-coal switching in Asia, global CO2 emissions from coal grew by 1.6% or 243 Mt, far exceeding the last decade’s average growth rate, and reaching a new all-time high of almost 15.5 Gt.

◇ A strong expansion of renewables limited the rebound in coal power emissions. The renewables meet 90% of global growth in electricity demand in 2022.
◇ CO2 growth in 2022 was well below global GDP growth of 3.2%.
◇ Of the overall increase of 321 Mt CO2, extreme temperatures contributed 60 Mt by cooling and heating demand from extreme weather. This accounted for almost one-fifth of the total global increase in CO2 emissions.
Regarding emissions from fossil fuels, the report shows that although last year’s growth was much slower than 2021’s rebound of more than 6%, emissions are continuously increasing and hinder efforts to meet global climate goals. In the midst of calls for CO2 emission reductions around the world, it is ironic that almost one-fifth of the total global increase in CO2 emissions last year were the result of increased demand for cooling and heating due to extreme weather conditions. As the frequency and severity of extreme heat and cold waves are intensified by climate change, this trend is expected to continue.
Because emissions are still putting the planet on an unsustainable and dangerous global warming pathway, the IEA urges accelerating the transition to clean energy, including renewables, electric vehicles (EV), and heat pumps, and to intensify actions on the path to achieving targets to prevent a worsening climate crisis.
