En ny rapport fra det Internationale Energiagentur (IEA) konkluderer, at energirelaterede CO2-emissioner i 2022 steg med 0,9 % sammenlignet med sidste år.
Rapporten har fokus på udviklingen i energirelaterede CO2-udledninger og fremhæver blandt andet:
- CO2 growth in 2022 was well below global GDP growth of 3.2%, reverting to a decade-long trend of decoupling emissions and economic growth that was broken by 2021’s sharp rebound in emissions. Improvements in the CO2 intensity of energy use were slightly slower than the past decade’s average.
- Emissions from natural gas fell by 1.6% or 118 Mt, following continued tightening of supply exacerbated by Russia’s invasion of Ukraine.
- Increased emissions from coal more than offset reductions from natural gas. Amid a wave of gas-to-coal switching during the global energy crisis, 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.
- Emissions from oil grew even more than emissions from coal, rising by 2.5% or 268 Mt to 11.2 Gt. Around half of the increase came from aviation, as air travel continued to rebound from pandemic lows, nearing 80% of 2019 levels.
- A strong expansion of renewables limited the rebound in coal power emissions. Renewables met 90% of last year’s global growth in electricity generation.
- The European Union saw a 2.5% or 70 Mt reduction in CO2 emissions despite oil and gas market disruptions, hydro shortfalls due to drought, and numerous nuclear plants going offline.
- US emissions grew by 0.8% or 36 Mt. The buildings sector saw the highest emissions growth, driven by extreme temperatures.
- China’s emissions were relatively flat in 2022, declining by 23 Mt or 0.2%.
- Emissions from Asia’s emerging market and developing economies, excluding China, grew more than those from any other region in 2022, increasing by 4.2% or 206 Mt CO2.
