The International Energy Agency (IEA) 2021 report wrote that “emerging markets and developing economies now account for more than two-thirds of global CO2 emissions, while emissions in advanced economies are in a structural decline,”.
China’s emissions have risen by approximately 6% in 2021 above 2019 highs.
“In 2021 alone, China’s CO2 emissions rose above 11.9 billion tonnes, accounting for 33% of the global total,” the IEA said.
“All fossil fuels should contribute to higher CO2 emissions in China in 2021, but coal is expected to dominate, contributing 70% to the increase, predominantly due to greater coal use in the power sector.”
Between 2019 and 2021, China’s emission output from coal-powered power plants has increased by approx. 7%. China was the only major economy to experience growth in both 2020 and 2021.
On the other hand, emissions in India grew by 1.4% from 2019 to 2021.
“CO2 emissions in India are now broadly on par with emissions in the European Union at 2.35 Gt, although they remain two-thirds lower on a per capita basis and 60% below the global average.”
The International Energy Agency (IEA) says the “increased use of coal was the main factor driving up global energy-related CO2 emissions”. Adding that “Coal accounted for over 40% of the overall growth in global CO2 emissions in 2021.”
The U.S. is seeing a reduction of 5.6% in emissions from 2019 to 2021, and are 21% below 2005 levels, the 2021 IEA report finds.
However, in 2020 the world saw an overall reduction in emissions. “The Covid-19 pandemic had far-reaching impacts on energy demand in 2020, reducing global CO2 emissions by 5.2%.”
