EPCA Report - Report on priority measures to reduce air pollution and protect public health in the matter of W.P. (C) No.13029 of 1985; M.C. Mehta v/s UOI & others. The report states that Delhi was able to arrest and lower air pollution with its first phase of action directed by the Hon’ble Supreme Court. But Delhi could not sustain these gains and air pollution levels are rising again. Growing pollution especially from vehicles and delayed action have enhanced public health risk.
