‘Chinese government statistics are not the only source of information on China’s energy use and greenhouse gas emissions. Using instruments that measure carbon dioxide (CO2) concentrations and monitor other air pollution trends, atmospheric scientists are able to get a second, independent view of China’s efforts to improve energy efficiency, particularly in heavily industrialized parts of the country. And, so far, the data suggest that those moves are making a difference.’
