Global CO2 emissions reached a record high in 2022
Communities around the world emitted more carbon dioxide in 2022 than in any other year on records dating to 1900. The high figure is a result of air travel rebounding from the pandemic and more cities turning to coal as a low-cost source of power.
Emissions of the climate-warming gas that were caused by energy production grew 0.9 per cent to reach 36.8 gigatons in 2022, the International Energy Agency reported Thursday. The mass of one gigaton is equivalent to about 10,000 fully loaded aircraft carriers, according to NASA.
Extreme weather events intensified last year's carbon dioxide emissions. Droughts reduced the amount of water available for hydropower, which increased the need to burn fossil fuels. And heat waves drove up the demand for electricity.
