The Global Carbon Project's annual report reveals that worldwide carbon dioxide emissions increased by 1.2 percent in 2025, reaching 37.8 billion metric tons despite record growth in renewable energy installations. The increase was driven primarily by rising natural gas consumption in developing economies and persistent coal use in parts of Asia.

While renewable energy capacity additions shattered records for the third consecutive year, the growth was insufficient to offset increasing overall energy demand. Researchers note that emissions must decline by roughly 7 percent annually to meet the goals of the Paris Agreement.

Climate scientists emphasized that the findings underscore the urgency of accelerating the transition away from fossil fuels, noting that the window for limiting global warming to 1.5 degrees Celsius above pre-industrial levels is rapidly closing.
