The aim of the survey was to help in formulation of policies as well as implementation of the measures in order to make these major metros sustainable.

Respondents take on air quality and water availability

• In the TERI survey, it was found that for the respondents, the air quality became worse or remained unaltered in six cities. The availability of the ground water on the other hand diminished except in the Chennai because it has more forest cover. The quality of surface water, in the meanwhile, became worse in five cities except in Mumbai.
• All these six metros witnessed a decline in number of species of animals and birds. The respondents saw deteriorating waste management in Delhi, Bangalore, Chennai and Hyderabad, but in Mumbai and Kolkata, improvement was observed. Availability as well as quality of the drinking water improved in these six cities, except in the city of Hyderabad.
• On the grounds of public awareness regarding environmental policies, it was observed by the TERI survey that respondents in Delhi had significantly low level of awareness while in Chennai, respondents were not adequately aware of various policies on climate change as well as air pollution.
• Most of the respondents in other cities knew about these policies on climate change and forest conservation but they felt that these policies were not implemented properly or were not up to the mark.

Major points of the TERI survey

• The TERI survey indicated that worsening of the air quality in the six major cities of India was because of economic development of the country.
• The contributors of rising air pollution were transport sector followed by the factories in as well as around the cities of Mumbai, Delhi, Chennai and Kolkata.
• In Bangalore, factories were rated as the major contributors of the air pollution, followed by transport. In Hyderabad, construction activities were considered as the worst offenders, followed by transport sector.
• Apart from this, rapid urbanization was the major cause of worsening environmental conditions, which led to pressure on limited availability of the land.
