Clean air is fundamental to human health, environmental sustainability and economic well-being.As urbanisation and economic activity expand, addressing air pollution has become an important global priority. Recognising this need, the global community has placed clean air at the centre of environmental action.

The International Day of Clean Air for Blue Skies is observed globally on 7 September. The United Nations General Assembly designated the day in 2019 to strengthen global action against air pollution. It stressed the importance of raising public awareness at all levels and promoting and facilitating actions to improve air quality. India observes this occasion as Swachh Vayu Diwas, linking the global campaign with national priorities.

The Government of India is addressing this complex challenge through a comprehensive, multi-sectoral approach. This approach combines air-quality monitoring, emission control and city-specific action plans. The Central Government is supporting States and cities through targeted programmes and policy interventions. State Governments and district administrations play a critical role in implementing these measures on the ground. These combined efforts address pollution sources while strengthening institutional capacity for sustained air-quality management.

India in Action to Mitigate Air Pollution

National Air Quality Monitoring Programme (NAMP)

The Central Pollution Control Board initiated the National Ambient Air Quality Monitoring (NAAQM) programme. It was subsequently renamed NAMP.  Its objectives are to periodically evaluate air pollution, determine the status and trend of ambient air quality in the urban areas, estimate future changes, and ascertain violations of prescribed ambient air quality standards and health hazards.

As on March 2026, the ambient air-quality monitoring network in the country currently comprises 1,646 stations across 603 cities in 28 States and 7 UTs, including manual stations and real-time stations. Manual stations collect and analyse samples periodically, while CAAQMS provide continuous, real-time air-quality data.

The SAMEER mobile application and web portal provide near real-time AQI information for more than 292 cities, enhancing transparency and citizen awareness. Public Grievance Redressal Portals have also been established in all NCAP cities, enabling public participation in pollution control efforts.

Air Quality Index (AQI)

AQI is a simple tool for citizens to understand air quality. It classifies air quality into 6 categories, from Good to Severe, based on pollutant concentrations and their potential health impacts. AQI is calculated using eight pollutants: PM10, PM2.5, NO₂, SO₂, CO, O₃, NH₃ and Pb, with the worst-performing pollutant determining the overall AQI.

National Clean Air Programme (NCAP)

To address air pollution in urban areas in mission mode, NCAP was launched in 2019 by the Government in 130 cities across the country. It is a multi-sectoral initiative involving the coordinated efforts of the Central and State Governments, Urban Local Bodies (ULBs) and other stakeholders. NCAP emphasizes source specific mitigation measures through city, state, and national-level clean air action plans, and it is monitored by various committees constituted at Central, State and District level.

Digital Tracking of Clean Air Progress

“PRANA” – Portal for Regulation of Air-Pollution in Non-Attainment cities, is a portal for managing and monitoring the implementation of the National Clean Air Programme (NCAP). It supports tracking the physical as well as financial status of city air action plan implementation and disseminates information on air quality management efforts under NCAP to the public. Information related to various activities and their progress under NCAP by various stakeholders is available on this portal, which will help in future policy decisions. Click To Reach Portal

Swachh Vayu Survekshan

Swachh Vayu Survekshan is an annual assessment of 130 cities under the NCAP. Launched in 2022-23, it is an initiative of the MoEFCC. The assessment covers measures addressing major pollution sources and implementation of City-specific Clean Air Action Plans. It promotes healthy competition, innovation and accelerated action among cities to improve air quality.

Institutions Driving India’s Clean Air Goals

The Government of India has established a multi-level institutional framework to address air pollution. It brings together national regulators, State agencies, urban local bodies and specialised institutions for regulation, monitoring, enforcement, scientific assessment and coordinated action.

Central Pollution Control Board (CPCB)

CPCB is a statutory organisation established under the Water (Prevention and Control of Pollution) Act, 1974, and is entrusted with powers and functions under the Air (Prevention and Control of Pollution) Act, 1981. It works to improve air quality and prevent, control and abate air pollution in the country, while also providing technical services to the MoEFCC.

Commission for Air Quality Management (CAQM)

The Government enacted the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021 and constituted CAQM as a dedicated statutory body for coordinated management of air pollution across the NCR airshed. It also coordinates GRAP implementation across the NCR.

Graded Response Action Plan (GRAP)

The GRAP is an emergency response framework for managing worsening air quality in the National Capital Region. It brings multiple government agencies together to take graded and targeted measures based on the severity of pollution. The measures are triggered when Delhi’s AQI reaches or is expected to reach specified levels. GRAP uses air-quality data, weather forecasts and scientific assessments to enable timely action. Its four stages range from ‘Poor’ (AQI 201–300) to ‘Severe+’ (AQI above 450). Measures become progressively stricter as air quality deteriorates. They include controlling dust and emissions, regulating construction and industrial activities, and restricting certain vehicles. The Commission for Air Quality Management (CAQM) coordinates implementation across the NCR.

State Pollution Control Boards (SPCBs)

SPCBs of India are key regulatory bodies responsible for controlling environmental pollution. They are at the frontline of environmental regulation. Beyond their original responsibilities under the Water Act, Air Act, and Environment Protection Act, SPCBs today also monitor noise, manage hazardous and plastic waste, maintain inventories, set standards, and ensure compliance across an expanding industrial base.

These institutions provide a coordinated framework for addressing air pollution through regulation, monitoring, enforcement and scientific assessment. 

To bring greater transparency, consistency and efficiency in environmental regulation for industries, Government has made amendment to Air Act 1981 and Water Act 1974 and has notified uniform consent guidelines “Control of Air Pollution (Grant, Refusal or Cancellation of Consent) Guidelines, 2025 on 29th January, 2025 and Water Pollution (Grant, Refusal or Cancellation of Consent) Guidelines, 2025 on 30th January”.

A Unified Consent and Authorization Management System (UCAMS) has also been launched by CPCB to facilitate online processing of consent applications by all State Pollution Control Boards and Pollution Control Committees. This portal provides a solution for End-to-end online processing of grant, refusal, or cancellation of Consent and through this uniformity in fees, siting criteria, timelines will provide enhanced transparency and traceability. 

Way Forward

India’s clean-air efforts will increasingly focus on sustained, source-specific and science-based interventions. Strengthening air-quality monitoring further will enable better identification of pollution sources and emerging hotspots. Greater use of real-time data, forecasting and scientific modelling can support timely and targeted interventions. 

States, cities and district administrations will remain central to translating national programmes into measurable improvements on the ground. Cleaner mobility, improved public transport and greater adoption of clean fuels can further reduce emissions from transport. 

Strengthening dust management, waste processing and industrial emission controls will address major urban pollution sources. Urban greening and ecosystem restoration can provide additional environmental benefits while improving resilience. 

Continued innovation can enable cleaner technologies and more efficient pollution control systems. Public awareness and citizen participation will remain essential for sustaining behavioural change. India’s continued focus on collaborative governance and measurable outcomes can accelerate progress towards cleaner air and healthier communities.
