Rai emphasised that the scheme, that will be in force till January 15, is "surely" bringing down the level of pollutants in areas across the city and that a "little trouble has to be borne for big measures".
He said that all relevant data would be produced before the Delhi High Court, which has asked the AAP government to consider if the scheme can be restricted to a week.
Rai said the government would apprise the court that it will be able to undertake a "proper analysis" with 15 days' data in hand.
"We decided to make it a 15-day long programme so that we gather sufficient data which can be better looked into and prepare further blueprint," he said.

On the Court's observation that public transport was "inadequate" resulting in "inconvenience" to the public, Rai said that the government has increased metro frequency, augmented the fleet of buses and developed technology for buses.
Terming as "vague" the status report submitted by the government on implementation of the scheme, the court has sought information about the pollution caused by taxis running on diesel and CNG which have been kept out of the purview of the odd-even formula.
It also sought data related to changes in the pollution level between January 1 and 7, the day the scheme will have completed a week.
