National Clean Air Programme (NCAP) Goals
The NCAP was launched in 2019 with an initial target to reduce particulate pollution by 20-30% by 2024, using 2017 as the base year. The target has been revised to a 40% reduction by 2026, with 2019-20 as the reference years. Notably, only PM10 concentration is currently being considered for performance assessments.
