India - France sign "Mobilise Your City" Agreement

Since the quality of air in cities is getting poor day by day, it is very necessary to bring in green vehicles for transportation to reduce air pollution.

Thats a good move. They should have chosen Delhi too as its the most polluted city right now. 

Its certainly a good move. But what was the criteria of selecting the cities? If it aims to reduce carbon emissions from vehicles, shouldn't more polluted cities like Delhi, Mumbai be selected first?

I agree, they should have selected cities that are more polluted than the ones selected. Ahmadabad and Kochi are comparatively better and Nagpur is Gaddakaris choice.
