Europe is the leading geopolitical continent in defining and mobilising decarbonisation policies. For instance, the UITP - an organisation advocating sustainable mobility and public transport - has an EU office, but less well developed contacts with, for example, the US. The European Union Committee of the UITP wants to promote decarbonisation of urban mobility in Europe. Although Europe is nowadays the leading geopolitical continent with regard to lowering emissions, Europe is quickly losing ground to Asia, with countries such as China and South Korea. However, the 2014 "Global Green Economy Index™ (GGEI)" ranks 60 nations on their green economic performance, finding that the Nordic countries and Switzerland have the best combined performance around climate change and green economy.
