The National Clean Air Programme (NCAP) was launched in India in 2019 and aimed to significantly enhance the air quality in India by 2024 by reducing PM concentration by 20-30 per cent, which in 2022 has been extended to 2026, aiming to have a 40% reduction in pollution levels compared to 2017. The programme has faced challenges and shortcomings, as highlighted in the ‘Tracing the Hazy Air 2022 & 2023‘ reviews. The latest report evaluates the progress under NCAP and ambient air quality trends for 2023.
