Global energy-related carbon dioxide (CO2) emissions hit a record high in 2023, rising 1.1% to 37.4 billion tonnes, according to the International Energy Agency (IEA). The increase was fueled by increased fossil fuel use in countries affected by droughts, hindering hydropower production. Despite a 1.3% emissions growth in 2022, clean technology adoption, including wind, solar, and electric vehicles, helped curb the rise. China’s economic reopening, fossil fuel use in low hydropower output nations, and aviation sector recovery contributed to the elevated emissions. Extreme droughts accounted for 40% of the increase, highlighting the need for urgent emissions reductions.
