National Green Tribunal

Under the National Clean Air Programme (NCAP), Delhi achieved only a 16% reduction in PM10 levels, falling short of the 22% target, while neighboring cities like Noida and Alwar performed better. One-fifth of the 130 non-attainment cities showed zero reduction in pollution levels since 2017. The Environment Ministry's report submitted to the National Green Tribunal states that 103 cities have seen some improvement.
