NCAP Tracker is a joint project of news portal Carbon Copy and Maharashtra-based start-up Respirer Living Sciences.
It is designed to monitor the targets under the National Clean Air Program (NCAP) launched by the Central Government on January 10, 2019. It aims to reduce PM 2.5 and PM 10 concentrations by 20 to 30% in 102 cities by 2024, taking 2017 as the base year. Now some new cities have been added to this list. At the same time, according to the new target set in September 2022, pollutants are to be reduced by 40% by 2026. Bureau >> Delhi’s AQI 407 : Page 2
