This is the initiative of the Government of West Bengal to prepare and implement comprehensive clean air action plan to reduce particulate air pollution in non-attainment cities of West Bengal. The Hon’ble National Green Tribunal’s (NGT) order dated 6 August 2019 has added six new non-attainment cities (NACs) in West Bengal namely Howrah, Barrackpore, Haldia, Asansol, Raniganj and Durgapur to the list of the non- attainment cities. The order has directed, Action Plans need to be prepared by States for the additional 20 non attainment cities (NACs) on the pattern of 102 NACs within three months and after its approval by CPCB within two months, States must initiate time bound action on remediation within next three months. These cities require to submit the clean air action plans to the Air Quality Monitoring (AQM) committee within three months of the order. The action plans will be reviewed and examined by a three-member committee to implement the plan. These action plans are being prepared within the broader framework of the National Clean Air Programme (NCAP) that has set a generic target of 20–30 per cent reduction in particulate pollution by 2024.
