In 2012, the EU decreased its total carbon dioxide emissions by 2.3 per cent. Even though Poland has been given bad press in this matter, it managed to decrease them by 3 per cent. In the U.S., emissions were reduced by 4 per cent, while in China they continue to rise, albeit at a slower pace. The EU has launched a crusade against global warming, but other countries have a more pragmatic approach to the issue, which is why the climate summit in Warsaw may end in failure.
