He suggested undertaking a special drive in the city to remove construction and demolition waste and garbage every year before October.
"Garbage dumping and burning creates problem. We will have to work together and clean up garbage so that it does not create a problem. There has to be special clean-up drive in the month of July, August, or September that takes away all construction and demolition waste and garbage collected in the city," he said.
The CPCB member secretary also stressed the need to quickly and heavily invest in public transportation to reduce vehicular emissions.
"As policymakers, we have to quickly and heavily invest in public transportation. I head a task force to deal with similar situations ... the biggest difficulty is how do I do with the transportation?
"The moment you start thinking about banning cars, diesel cars, then how do we get people to the route? ...unless and until we have quick, a very robust, efficient, affordable convenient transportation system. Involve private people in this," he said.
Delhi has around 5,500 buses and 370 kilometers of metro network. Around 42 lakh people travel through buses, while 50.13 lakh opt for metro trains every day.
Gargava also said power plants emit sulphur dioxide and it's contribution to particulate matter pollution is huge.
"It is almost 25-30 percent of particles... Means we have to deal with gaseous emissions as well. All power plants in the country will have flue-gas desulfurisation technology to reduce air pollution.
