Exemptions could reduce efficacy of odd-even scheme

In a statement, Mr Sumit Sharma, Associate Director, Earth Science and Climate Change Division, TERI, said that odd-even has limited potential for reducing pollution in Delhi. As per TERI estimates, it led to reduction of four to seven per cent last year. TERI recommends its use for limited period only during air quality emergency conditions. Exemptions given in the scheme could further reduce its effectiveness, Mr Sharma said.
