I found different data. Perhaps the UK cut emissions by a larger % but US by nominal tons? https://www.forbes.com/sites/rrapier/2017/10/24/yes-the-u-s-leads-all-countries-in-reducing-carbon-emissions/#38387ad03535 https://www.forbes.com/sites/rrapier/2017/10/24/yes-the-u-s-... According to the 2017 BP Statistical Review of World Energy, since 2005 annual U.S. carbon dioxide emissions have declined by 758 million metric tons. That is by far the largest decline of any country in the world over that timespan and is nearly as large as the 770 million metric ton decline for the entire European Union. By comparison, the second largest decline during that period was registered by the United Kingdom, which reported a 170 million metric ton decline. At the same time, China's carbon dioxide emissions grew by 3 billion metric tons, and India's grew by 1 billion metric tons.
