Scientists reported that the world this year pumped more carbon dioxide into the air because of increased pollution from China and India.

The world in 2023 increased its annual emissions by 398 million metric tons, but it was in three places: China, India and the skies. China’s fossil fuel emissions went up 458 million metric tons from last year, India’s went up 233 million metric tons and aviation emissions increased 145 million metric tons.

Outside of India and China, the rest of the world’s fossil fuel emissions went down by 419 million metric tons, led by Europe’s 205 million metric ton drop and a decrease of 154 million metric tons in the United States.
