The odd-even rule is set to make a comeback in Delhi from April 15, but scientists seem to be divided over the success of the much-hyped formula that restricted plying of cars on the capital’s roads for the first 15 days of the year. According to a new research from the Indian Institute of Technology (IIT)-Roorkee, no “significant” change in air quality was registered after the odd-even scheme came into force in Delhi.
The study, conducted by the IIT-Roorkee’s civil engineering department and centre of excellence in disaster mitigation & management, has said the odd-even formula for cars implemented in Delhi from January 1 to 15 this year failed to bring significant improvement in air quality.
The researchers analyzed data from Delhi Pollution Control Board (DPCB) and Delhi Pollution Control Committee (DPCC) for four locations in Delhi – Mandir Marg, RK Puram, Punjabi Bagh and Anand Vihar. The data was for the month of December 2015 and January 2016…
…A study by researchers at the Energy Policy Institute at the University of Chicago (EPIC) and Harvard University had found reductions in pollutants in the afternoon hours in Delhi from January 1 to 15. According to the study, PM 2.5 declined by 13% on an average during the odd-even period.
