China rushes to build out solar, and emissions edge downward

High on the Tibetan plateau, Chinese government officials last month showed off what they say will be the world's largest solar farm when completed — 610 square kilometers (235 square miles), the size of the American city of Chicago. China has been installing solar panels at a blistering pace, far faster than anywhere else in the world, and the investment is starting to pay off. A study released Thursday found that the country's carbon emissions edged down 1% in the first six months of the year compared to a year earlier, extending a trend that began in March 2024.
