A report titled 'Toward Healthy Air for Patna', released yesterday by the Centre for Environment and Energy Development (CEED), also pointed out that as per the World Health Organisation (WHO), Patna was the second-most polluted city in India with high levels of concentrated particulate matter, six times more than what is considered safe.

"The exponential rise in air pollution in Patna requires an immediate robust plan to tackle it, and to spread massive awareness on high health risk posed by air pollution. The Bihar government must show strong political will to take immediate action to curb pollution now", CEED CEO Rampati Kumar told media persons here.

CEED suggested a 15-point programme to control air pollution, which includes implementation of clean energy, usage of clean fuel for cooking, improved transport system, and stringent emission targets for industries.

Last month, the state government banned 15-year-old diesel vehicles from Patna's roads in a bid to control air pollution. The decision followed an advisory by the Bihar State Pollution Control Board (BSPCB) that said air quality in Patna was very poor on 20 days and severe on nine days of November 2015.
