On April 21 2016, the CPCB had told NGT that there was no data to suggest that the odd-even scheme has led to a decline in vehicular pollution in Delhi-NCR. During the hearing, the Delhi government counsel told the bench that they were introducing the odd-even scheme in pursuance to the directions of the apex court-appointed EPCA. "The Supreme Court had never said that you implement the odd-even scheme. You have not followed 99 directions and introduced the odd-even scheme and treating it as a picnic," the bench said. The AAP government had on Thursday announced introduction of the odd-even scheme as part of a Graded Response Plan to tackle the alarming pollution levels in the capital.
