Asserting that air pollution is one of India's leading public health challenges, Congress leader Jairam Ramesh on Wednesday said cracking down on stubble burning will not suffice and there was a need to re-imagine India's economic and sustainability model, with a large-scale shift to renewable energy, electric vehicles, and public transport.

Ramesh also stressed it is time to redo The Air (Prevention and Control of Pollution) Act, 1981 to reflect the public health consequences of air pollution and also called for a review of the National Ambient Air Quality Standards, 2009.
