It's not that they don't do anything about it. In 2012 they emission of carbon dioxide raised by 3%, but that increase was at least lower than in previous years, where it oscillated around 10% (http://www.bbc.co.uk/news/science-environment-24742770 http://www.bbc.co.uk/news/science-environment-24742770) 29 of 71 nuclear reactors that under currently under construction are being built in China (http://world-nuclear.org/info/Facts-and-Figures/World-Nuclear-Power-Reactors-and-Uranium-Requirements/ http://world-nuclear.org/info/Facts-and-Figures/World-Nuclea...), they also have similar numbers for hydropower (see the previous link).
