Prague, the capital of the Czech Republic, is also the centre of the country’s economic, political and cultural activity. It is home to one-tenth of the country’s population, and contributed around 24% of the Czech Republic’s GDP in 2007. Trade, tourism, transport and communications together made up one-third of Prague’s GDP in that year, while industry contributed only 13%, less than one-half of the national average shares of 32.6%, in one of the EU’s most industrialised economies. During the past 20 years of economic transition, Prague has seen a structural shift away from production and towards business-related services, and a number of multinational firms have their European headquarters in the city. Prague is ranked 24th overall in the European Green City Index, with a score of 49.78 out of 100. The city performs best in the categories of water, waste and land use, ranking in the top half of the index for these categories.
