In this episode of Metro Matters, Shivani Singh, speaks to Sunita Narain, member of the Supreme Court-mandated Environment Pollution (Prevention and Control) Authority (EPCA), about the hits and misses in Delhi's fight against air pollution. Supporting the Delhi government's decision to enforce odd-even road space rationing from November 4-15, Narain backed the inclusion of two-wheelers in the plan. Narain said she hopes that the arrangement will be brought in every time pollution levels turn severe in the city.
