Greenpeace India emphasised that air pollution is not restricted to Delhi and the national capital region.
"The graded response system in Delhi is a very important milestone indeed, but we still have miles to go in order to let the country breathe.
"The lessons learnt from Delhi must be implemented in areas around the Indo-Gangetic Plains and entire India, which have equally deplorable air quality due to particulate matter from coal, oil and biomass," said Sunil Dahiya, campaigner, Greenpeace India.
"These measures, which include, higher parking charges, greater investment in public transport and pollution free mobility, measures to stop garbage burning and strict enforcement of PUC norms as well as emission standards for power plants and industries, need to be in force all year-round.

"Once the pollution levels become critical, it is too late. Pollution levels take days to build up and implementing the measures introduces more delay. No country has solved its air pollution problems by tying enforcement of standards to wind conditions only," he pointed out.
Greenpeace said an IIT Kanpur study mentioned that 13 thermal power plants within a 300 km radius of Delhi need to be regulated to see significant improvements in air quality in the national capital.
"So it's important that the the emergency measures also include directions to shut down those power plants, along with Badarpur," Dahiya said.
"The proposed new thermal power plant standards must come into force as soon as possible. Plant operators will only be able to reduce pollution load significantly if the pollution control devices are installed without any further delay.
"Any further delay will cost the lives of thousands of Indians. The government must resist any pressure to delay implementation of new fuel standards as well," he said.
Greenpeace India also called for a comprehensive and systematic national action plan.
