Emissions of the climate-warming gas that were caused by energy production grew 0.9% to reach 36.8 gigatons in 2022, the International Energy Agency reported. The mass of one gigaton is equivalent to about 10,000 fully loaded aircraft carriers, according to NASA.
Carbon dioxide is released when fossil fuels such as oil, coal or natural gas are burned to powers cars, planes, homes, and factories. When the gas enters the atmosphere, it traps heat and contributes to the warming of the climate.
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 demand for electricity.
The report was described as disconcerting by climate scientists, who warn that energy users around the world must cut emissions dramatically to slow the dire consequences of global warming.
