Global carbon dioxide emissions hit another record high in 2023, but the increase was smaller than the previous year due to the strong expansion of renewable sources, the International Energy Agency reported Friday.


According to the IEA’s annual CO2 emissions report for 2023, energy-related carbon dioxide emissions hit a record level of 37.4 billion tonnes, a rise of 410 million tonnes from the previous year.

The yearly increase is lower than 490 million tonnes reported in 2022, due to strong growth in clean energy sources.

Emissions from coal, the dirtiest fossil fuel, accounted for 65% of the increase.

Extreme droughts across the world were key contributors to the rise in emissions last year, as they led to a shortfall in hydropower output and caused countries like the U.S. and China to turn to fossil fuels to cover the gap.

The report notes that without this shortfall, emissions from electricity generation would have fallen in 2023.

The agency said post-pandemic economic growth in both India and China has been “energy intensive,” while increased reliance on fossil fuels in 2023 due to poor rainfall led to a rise in CO2 emissions of 190 million tonnes and 565 million tonnes, respectively. Read more.
