The Asian Green City Index, a study commissioned by Siemens and performed by the independent Economist Intelligence Unit, analysed the aims and achievements of major Asian cities with respect to environmental and climate protection.
From India, four cities feature in the report.
The Asian Green City Index examines the environmental performance of 22 major Asian cities in eight categories: energy and CO2, land use and buildings, transport, waste, water, sanitation, air quality and environmental governance.
The EIU developed the methodology in cooperation with leading urban experts around the world, including representatives of the OECD, the World Bank and Asia’s regional network of local authorities, Citynet.
“The study of Asian cities shows one thing very clearly: higher income does not necessarily mean higher resource consumption. While resource consumption increases substantially up to an annual gross domestic product of about $15,000 per capita, it drops again when income rises beyond this,” said Jan Friederich, research head of the EIU study.
This is primarily because in prosperous Asian cities, environmental awareness is greater and infrastructures are more efficient. These cities are actively cutting their consumption of natural resources and are thus developing more sustainably.
The 22 Asian cities use an average of 277 litres of water per person per day, which is slightly higher than the figure for Latin America, 264 litres, but lower than the figure for Europe, at 288 litres.
