Copenhagen is the “greenest” major city in Europe, followed by Stockholm, Oslo, Vienna, and Amsterdam. This is the conclusion reached by a unique study of the environmental sustainability of 30 major cities in 30 European countries that Siemens presented during the UN Climate Change Conference in Copenhagen. In addition to analyzing these cities’ achievements and objectives in the area of environmental and climate protection, the European Green City Index makes the differences transparent. The study evaluates the 30 cities in eight categories: CO2 emissions; energy; buildings; transportation; water; air quality; waste and land use; and environmental governance.

Scandinavian cities generally achieve high scores. Awareness of environmental protection in these cities has been strong for years, which is reflected in the cities’ ambitious climate targets. Copenhagen, for example, aims to be carbon free by 2025. In Scandinavian countries, GDP per capita income is above average, and these wealthy countries have invested substantially in environmental protection. So far, Eastern European cities generally rank lower. This is largely due to a comparatively low gross domestic product and historic burdens, including the lack of attention paid to environmental protection in previous decades. In particular, high energy consumption in buildings and outdated infrastructures reflect this. In the area of public transportation, however, Eastern European cities often score above average: Kiev, which is ranked 30th overall, is estimated to have the highest percentage of people using public transportation to commute.

The scope of the European Green City Index is unique. The eight categories are based on 30 individual indicators — 16 of which are quantitative (e.g. consumption of water and energy per capita, recycling rate, and use of public transportation) and 14 qualitative (e.g. CO2 reduction targets, efficiency standards for buildings, and support for environmental protection measures).
