A report issued by The Energy and Resources Institute (TERI) on Tuesday revealed that the odd-even phase II in Delhi failed due to several factors including heat, industrial pollution and crop burning in the Delhi-NCR region.
The report acknowledges that the odd-even scheme, which was launched between 15 April and 30 April, 2016, was successful in raising public awareness about air pollution and in improving the traffic situation, but cautioned against regularising the scheme saying the rule should at best be used as an emergency measure only.
"If you repeat odd-even too often, people buy second cars or begin using taxis frequently," said Ajay MAthur, TERI Director General, reported India Today. He also recommended several measures such as congestion pricing, hiked parking charges and improved public transport to be paired with the odd-even scheme to cut levels of pollution in the city.
TERI's observations for the second phase of the scheme were based on a methodology of analysing air quality in the city across nine locations, issuing a daily data report for the previous 24 hours.
According to the report, pollutants like Particulate Matter (PM 2.5, PM 10) and Nitrogen Dioxide (NO2) shot up by wider margins during the period when the odd-even scheme was implemented in the city. The PM 2.5 rose by 39%, PM 10 by 26% and NOX by 25%.
The car volume went down by 17% in phase II in comparison to 21% in odd-even phase I and vehicular speed increased by merely 13% as opposed to 17% in odd-even phase I.
