Siemens: Green city index

Source: Siemens. http://www.siemens.com/entry/cc/en/greencityindex.htm

The green city index was developed by Siemens. Green city index reports are developed for Europe,
Asia, South America, North America, and Africa. The green city index focuses on environmental
performance and the categories and indicators vary between the different geographical indices.
Eight categories are used in the European version index: CO2 emissions, energy, buildings, transport,
water, waste and land use, air quality and environmental governance; 16/30 indicators are derived
from quantitative data (how the city is performing) and 14/30 of the indicators are qualitative
assessments of the cities ambition and aspirations.

major cities – A research project conducted by the Economist Intelligence Unit, sponsored by
