Presenting its report card on the odd-even scheme to the Delhi High Court on Friday, the Kejriwal government admitted that pollution has risen while saying emergency level pollution has come down.

The government presented a report by the Environment Pollution (Prevention and Control) Authority (EPCA). The government, through senior advocate Harish Salve, deposed that the scheme was one of the many measures taken by the government to control pollution.

Responding to the query by the division bench of the Chief Justice G Rohini and Justice Jayanth Nath of whether a week's time was enough to derive a conclusion from the the pilot project, Salve said, "The finding says there is a definite positive effect from the odd-even scheme and suggested that the scheme should be extended for more than two years."

Rahul Mehra, senior standing counsel for Delhi government said the project was based on a study conducted in Beijing, which had adopted the scheme for a period of 15 days in 1998.

As per the report, November 2015 had a significant higher number of days in the severe category against those in November 2014. While the statistics were similar for the month of December for both the years, it went on to add that though December 2014 had at least three days in the good and satisfactory category as described by the Air Quality Index (AQI), December 2015 had none.

Sunita Narain, Director General, Centre for Science and Environment and the member of EPCA said, "EPCA has the analysed the same data presented by the petitioners and has made its inference. Even when conditions were favourable, the pollution levels were high, though, if one has to compare it during this period (oddeven scheme), it generally has a positive effect." Transport Minister Gopal Rai and senior AAP leader Ashish Khetan were present.
