According to latest Environment Pollution Control Authority (EPCA) report, Delhi Government’s Odd-Even scheme is working well as it has managed to bring down the peak level of pollution in the national capital to its “lowest.”


EPCA, which has been appointed the Indian Supreme Court to monitor Delhi’s pollution level, also said that Delhi’s car rationing scheme has reduced the traffic volume on the Capital’s roads. This, it says, has helped immensely in bringing down the peak level of pollution in the national capital.


The report further states that both particulate matter and nitrogen oxide that are emitted from cars have reduced substantially since the initiative started and is down by as much as 40%.


Earlier this week, TY News had reported how peak hour traffic volume in Delhi dipped by 30% due to the scheme thereby bringing in a different kind of relief on the roads.

It seems the odd-even formula is working for Delhi, and the above results are validating the importance of the car rationing measure that Delhi government suggested.


In its report the EPCA panel also observed that the current weather condition in Delhi is at “emergency levels” while the peak level of pollution is at its “historic low”.

The EPCA also disclosed that they have based their findings on the data provided by the Delhi Pollution Control Committee (DPCC) and the Centre for Science and Environment (CSE).


To validate their findings, the panel compared the current Peak Level data with that of data from November and December last year, and found that in these two months they were were at 606 and 524 micrograms per cubic metre as compared to 391 micrograms per cubic metre in January 2016.

The report further stated:

“The earlier smog episodes have seen much higher peaks and much more rapid build up compared to the rise that happened during the first week of odd and even programme. This proves reduced traffic volume has arrested the peaking of pollution.”

Implying the consequence of this result, the report states that the fall in quantity of particulate matters and oxides of nitrogen indicates that there is a reduced exposure to toxic pollution from vehicles on roads and close to road side, where the maximum impact of pollution is felt.


Though the report also states that even with this reduction in peak level pollution, there has not been a single good air quality day in Delhi this winter.

The report also points out that in November 2015, Delhi had 73% days in ‘severe’ category as compared to 53% in November 2014.


As for December 2015, Delhi had 67% days in ‘severe’ category days as against 65% in December 2014.

The Delhi High Court is set to take a call on Monday on whether to let the odd-even scheme continue after January 15, as was the initial proposal of Arvind Kejriwal-led AAP Government.
