Key Highlights
- Vehicular emission was not a dominant enough factor to impact pollution
- NGT had diretced CPCB to submit data after receiving a plea
- CPCB monitored pollutants between 1 - 14 April and 15 - 30 April
The Central Pollution Control Board (CPCB) recently advised the National Green Tribunal (NGT) that the decrease in vehicular emission during the second phase of odd-even formula did not affect Delhi's pollution levels. The second phase of the odd even rule in Delhi came into effect on 15 April, 2016 and ended on 30 April. Other than having no effect on pollution levels, the traffic situation was also reported to have worsened. A government panel's report in May had lakhs of private and CNG vehicles, which were not present during the first phase, as the reason why city's traffic crawled during the second phase.
The green court had asked CPCB to present the ambient air quality data after during the hearing for a petition filed by scientist Mahendra Pandey. Pandey alleged that vehicular emission did not have a major effect on pollution and had requested independent monitoring of the air quality index.
About its impact on the pollution levels, the CPCB report said, "The decrease in vehicular emission was not a dominant enough factor to impact observed data. Since meteorological factors as well as emission from various sources outside Delhi in the air-shed varies from time to time, data for different periods do not lend themselves to scientifically accurate comparison." It must be noted that CPCB monitored several pollutants not only during the second outing of the odd-even rule, but also before it, between 1 April and 14 April.
