Good news from IEA: CO2 emissions to grow less in 2022 than last year

If last March we reported that "Global CO2 emissions returned to the highest level in history" new analysis by the IEA International Energy Agency showed yesterday that global CO2 emissions emissions from fossil fuel combustion are expected to grow by just under 1% this year, only a small fraction of their increase last year, as a strong expansion of renewables and electric vehicles prevents a much sharper rise. That’s despite this year’s increase is driven by power generation and by the aviation sector, as air travel rebounds from pandemic lows. And widespread concerns of a rush back to coal, oil and gas amid a global energy crunch and Russia’s war in Ukraine.


Solar PV and wind are leading an increase in global renewable electricity generation in 2022 of more than 700 terawatt-hours (TWh), the largest annual rise on record. Without this increase, global CO2 emissions would be more than 600 million tonnes higher this year. And despite the challenging situation that hydropower has faced in several regions due to droughts this year, global hydropower output is up year-on-year, contributing over one-fifth of the expected growth in renewable power. 


The article concludes that “… promising signs of lasting structural changes to the CO2 intensity of global energy are evident in 2022 – and they are set to be reinforced by major increases in government support for clean energy investment, notably in the US Inflation Reduction Act, as well as in decarbonisation plans such as the European Union’s Fit for 55 package and Japan’s Green Transformation (GX) plan, and in ambitious clean energy targets in China and India.”
