The Green City Index methodology was developed
by the Economist Intelligence Unit (EIU) in cooperation with Siemens. Cities
were selected for their size and importance (mainly capital cities and large
population or business centres). They were picked independently, rather than
relying on requests from city governments to be included or excluded, in order
to enhance each Index’s credibility and comparability.
More than 20 global
experts in urban environmental sustainability from the following organisations
advised the EIU in developing the methodology for the Green City Indexes: ■
African Development Bank ■ Cambridge University ■ CITYNET (Regional Network of
Local Authorities for the Management of Human Settlements) ■ European
Commission ■ Ford Foundation ■ Harvard University ■ ICLEI (Local Governments
for Sustainability) ■ ISOCARP (International Society of City and Regional
Planners) ■ Inter-American Development Bank ■ Karlsruhe University ■ Natural
Resources Defense Council ■ New York University ■ OECD (Organisation for
Economic Cooperation and Development) ■ Regional Plan Association ■ Technical
University Munich ■ UN-Habitat ■ University of Pennsylvania ■ URBACT ■ Vienna
Institute for Urban Sustainability ■ World Bank
