Carbon Dioxide Emissions Head for Another Record in 2025

Global fossil fuel emissions are on track to soar to record highs in 2025 and show no signs of declining overall, although there are indications of a recent slowdown in China’s emissions, researchers said on Wednesday.

This year, nations are projected to emit roughly 38.1 billion tons of planet-warming carbon dioxide by burning oil, gas and coal for energy and by manufacturing cement, according to data from the Global Carbon Project. Those sources are the largest contributors to human-caused climate change. The total is roughly 1.1 percent more than the world emitted in 2024.
