Budapest is Hungary’s capital and its main hub of economic, financial, political and cultural activity. With about 17% of the country’s population, Budapest contributed 34% of Hungary’s GDP in 2006. The city’s primary commercial activities are financial and business services, which account for close to 80% of gross value added. The capital traditionally had a stronger industrial focus, but many factories have closed since the transition from communism in 1989, and this has had a beneficial effect on the city’s over-all environmental impact. Budapest ranks 17th among the 30 cities in the European Green City Index, with a score of57.55 out of 100. However, when compared with other low-income cities it ranks third. This relatively good performance can be attributed in part to the reduced importance of industry to the city’s economy.
