National Clean Air Programme (NCAP), Objectives, Features

The National Clean Air Programme (NCAP) was launched in 2019 by the Ministry of Environment, Forest and Climate Change to improve air quality in over 100 cities. It focuses on sector-specific actions, strengthening monitoring networks, enhancing public participation, and integrating policies across transport, industry, agriculture, and urban management to tackle air pollution effectively.

The National Clean Air Programme (NCAP) targets a reduction of PM10 levels by up to 40% or achieving the national standard of 60 µg/m³ by 2025–26 from 2019–20 levels. While progress has been made in dust control, industrial emissions, transport, and waste management, weak enforcement and seasonal pollution events continue to pose challenges.

National Clean Air Programme About

National Clean Air Programme (NCAP), launched by the Ministry of Environment, Forest and Climate Change (MoEFCC) in January 2019, aims to improve air quality in 130 non-attainment and Million-Plus cities across 24 States/UTs.

• Major cities covered include Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, Ahmedabad, Pune, Lucknow and Patna.
• The programme adopts a multi-sectoral, source-specific approach through City, State and national-level clean-air action plans, involving Central and State Governments, Urban Local Bodies (ULBs) and other stakeholders.

National Clean Air Programme Target

The target is to reduce PM10 levels by 40% or meet national ambient air quality requirements (60µg/m3) by 2025-26, compared to 2019-20 levels. These interim targets align with global experience: city-specific actions achieved 35%-40% PM2.5 reductions in five years in cities such as Beijing and Seoul, while Santiago and Mexico City saw 73% and 61% reductions in PM2.5 and PM10 concentrations over 22 to 25 years, respectively.

• Funds Released and Utilised: ₹13,415 crore has been provided to 131 cities as performance-linked critical-gap funding, of which ₹9,929 crore (74%) has been utilised.
• Convergence of Resources: NCAP leverages resources from Central schemes such as Swachh Bharat Mission (Urban), AMRUT, Smart Cities Mission, SATAT and Nagar Van Yojana, along with contributions from State/UT governments and urban authorities.
• City Action Plans: Funds support source-specific measures under City Action Plans (CAPs), with annual action plans reviewed by CPCB to ensure compliance with NCAP guidelines.
• Skewed Expenditure: Spending is concentrated on road-dust management (68%), followed by transport (14%) and waste management and biomass burning (12%), while industry, domestic fuel use and public outreach each receive less than 1%, and capacity building and monitoring account for only 3%.
• Monitoring and Accountability: The Portal for Regulation of Air-pollution in Non-Attainment Cities (PRANA) portal tracks the physical and financial progress of NCAP, while national-, state-, and city-level committees monitor implementation and fund utilisation.

National Clean Air Programme Pollutants

The National Clean Air Program focuses on particulate matter pollutants (PM10 and PM2.5) to reduce their ambient concentrations in selected non-attainment cities.

• PM10: Coarse particulate matter with a diameter of 10 micrometers or smaller. The initiative aims to reduce yearly average PM10 levels to national requirements of 60 µg/m³.
• PM2.5: Fine particulate matter with a diameter of 2.5 micrometers or less. These small particles penetrate deep into the lungs and are tracked alongside PM10 as key indicators of urban air toxicity.

National Clean Air Programme Features

National Clean Air Programme (NCAP) proposes actionable steps to reduce air pollution across urban and regional areas:

• NCAP Funding: Under the National Clean Air Programme (NCAP), ₹2,862.03 crore has been cumulatively released to non-attainment cities from FY 2019–20 to date.
• 15th Finance Commission Grants: Additionally, ₹13,561.53 crore has been provided to 42 million-plus urban agglomerations under the 15th Finance Commission grants since FY 2020–21.
• City Action Plans: City Action Plans (CAPs) in 130 cities are being implemented through coordinated efforts of state governments and their agencies at both state and city levels.
• Resource Convergence: CAP implementation is supported by pooling funds from schemes such as SBM (Urban), AMRUT, Smart Cities Mission, SATAT and PM E-Drive, along with contributions from State/UT governments and urban and industrial development agencies.
• Supplementary Support: NCAP and XV-FC funding serves as performance-linked supplemental grants, addressing critical funding gaps that remain after other available resources are utilised.

National Clean Air Programme Approach

National Clean Air Programme (NCAP) adopts a comprehensive and adaptive approach to reduce air pollution effectively across cities and regions:

• Collaborative Governance: Implementation depends on strong coordination between central ministries, state governments, and local bodies to ensure action at all levels.
• Policy Integration: NCAP aims to align and mainstream existing policies, particularly those under the National Action Plan on Climate Change (NAPCC).
• Synergy with NAPCC Missions: It coordinates with five key missions - Solar Energy, Enhanced Energy Efficiency, Sustainable Habitat, Green India, and Sustainable Agriculture for holistic pollution control.
• Reorientation of Policies: Current measures are refined, expanded, and implemented in a faster, time-bound manner to achieve cleaner air.
• Smart City Leverage: The 54 Smart Cities among the non-attainment cities act as demonstration hubs to scale up successful clean air initiatives.
• Adaptive Framework: NCAP is designed to be flexible, incorporating new scientific findings and global best practices for ongoing enhancement.

National Clean Air Programme Implementation

National Clean Air Programme (NCAP) is executed through a coordinated framework that engages multiple ministries and agencies to manage air pollution effectively:

• CPCB Role: Under the Air Act, 1981 (Sec. 16(2)(b)), the Central Pollution Control Board (CPCB) is responsible for the nationwide prevention, control, and abatement of air pollution.
• Institutional Framework: NCAP is coordinated through inter-sectoral groups involving ministries, NITI Aayog, CPCB, industry, academia, and civil society to ensure integrated action.
• Vehicular Pollution Control: The Ministry of Road Transport and Highways (MoRTH) serves as the nodal agency for regulating vehicle emissions under the Motor Vehicles Act, 1988, and Central Motor Vehicle Rules, 1989.
• Sectoral Ministries’ Role: Ministries like MoEF&CC, Power, Petroleum & Natural Gas, Renewable Energy, Heavy Industry, Housing & Urban Affairs, and Agriculture integrate air quality measures into their sectoral policies.
• Synergy with NAPCC: NCAP complements the National Action Plan on Climate Change (NAPCC) by working in tandem with missions like Green India, Energy Efficiency, Solar, Sustainable Habitat, and Sustainable Agriculture, ensuring that air quality improvement is achieved alongside broader climate goals.
• Working Groups: Sector-specific groups define objectives, strategies, and timelines to guide implementation and ensure monitoring.
• Monitoring & Evaluation: Component-wise documents and the Apex Committee review progress, develop performance indicators, and report annually on air quality improvements and emission reduction benefits.

• Policy Integration: NCAP has been linked with other flagship government schemes, ensuring convergence of resources, institutional strengthening, and long-term management of air quality.

National Clean Air Programme Achievements

National Clean Air Programme (NCAP) has led to several significant achievements by reducing pollution levels, expanding monitoring systems, and mobilising funds for city-level action.

• Revised Pollution Reduction Target: The original target of 20-30% reduction in PM10 concentrations by 2024-25 was revised to up to 40% reduction or achievement of the PM10 NAAQS (60 µg/m³) by 2025-26, making the programme more ambitious.
• Reduction in PM10: Of the 100 NCAP cities with adequate data, 77 recorded a reduction in PM10 concentrations. 51 cities achieved the initial 20-30% reduction target, while 23 achieved the revised 40% reduction target.
• Expansion of Monitoring Network: In 2025, India had 1,600 air-quality monitoring stations, comprising 565 CAAQMS and 1,035 manual stations, covering 584 cities across 28 states and 7 Union Territories.
• Strengthening Scientific Assessment: 90 of 130 NCAP cities have completed source-apportionment studies, enabling identification of major pollution sources and formulation of targeted interventions.
• City-Specific Action: National Clean Air Programme (NCAP) has promoted city-specific action plans and targets, allowing pollution-control measures to be tailored to local emission sources and conditions.
• Persistent Pollution Challenge: Despite progress, 190 of 229 cities with adequate PM10 data exceeded the NAAQS in 2025, while 103 of 231 cities with adequate PM2.5 data exceeded the NAAQS, indicating that reductions have not yet translated into compliance in many cities.

National Clean Air Programme Challenges

National Clean Air Programme (NCAP) has strengthened India’s air-pollution management framework, but its effectiveness remains constrained by persistent gaps in monitoring, compliance, source-based planning, regional coordination, and implementation:

• Inadequate Monitoring: Gaps in monitoring coverage and data quality hinder effective pollution assessment. 28 of 130 NCAP cities lack CAAQMS, while poor maintenance and non-compliance with CPCB siting guidelines affect data reliability.
• Limited Compliance with Air-Quality Standards: Pollution reduction has not consistently translated into compliance with NAAQS. Although 77 of 100 cities with adequate PM10 data recorded reductions, 68 of these still exceeded NAAQS; nationally, 190 of 229 cities exceeded the PM10 standard in 2025.
• Insufficient Focus on PM2.5: Continued high PM2.5 levels indicate the need to address fine particulate matter and its precursor gases more effectively. 103 of 231 cities with adequate PM2.5 data exceeded NAAQS in 2025.
• Inadequate Source-Based Planning: Limited source-apportionment studies constrain targeted interventions. Only 90 of 130 NCAP cities have completed source-apportionment studies, leaving around 40 cities without scientific identification of major pollution sources.
• Regional and Transboundary Pollution: City-level measures are insufficient when pollution crosses administrative boundaries. In the IGP, 60 of 61 cities with adequate PM10 data exceeded NAAQS, while all 14 NCR cities exceeded the standard.
• Sectoral and Funding Imbalance: Pollution-control spending is concentrated on road dust, while other sources receive limited attention. 68% of expenditure goes to road-dust management, compared with 14% for transport and 12% for waste management and biomass burning; industry and domestic fuel use each receive less than 1%.
• Implementation and Fund-Utilisation Gaps: Financial allocation has not fully translated into implementation. Of ₹13,036.52 crore provided to NCAP cities, only 74% has been utilised, indicating gaps in execution and institutional capacity.

National Clean Air Programme Way Forward

National Clean Air Programme (NCAP) can deliver stronger and more sustained improvements by shifting from city-level particulate reduction to source-based, outcome-oriented and regional air-pollution management.

• Prioritise PM2.5: NCAP should place greater emphasis on PM2.5 and its precursor gases, with measurable city- and state-specific targets, given the greater health risks associated with fine particulate matter.
• Strengthen Source-Based Action: Pollution-control measures should be aligned with source-apportionment studies, ensuring that interventions target the dominant local emission sources rather than relying disproportionately on road-dust control.
• Adopt an Airshed Approach: Pollution crossing city and state boundaries requires regional airshed-based planning, particularly across the Indo-Gangetic Plain and NCR, with coordinated action among states and urban authorities.
• Strengthen Enforcement: NCAP should be supported by stricter, time-bound emission standards and effective compliance mechanisms for industries, vehicles, construction, waste burning and other major sources.
• Link Funding to Outcomes: Financial support should be increasingly tied to measurable air-quality improvements, implementation performance and source-specific action, while improving fund utilisation by cities.
• Expand Monitoring and Scientific Capacity: Monitoring infrastructure should be strengthened, especially in cities without CAAQMS, alongside better maintenance, data quality, source apportionment and technical capacity of CPCB, SPCBs and ULBs.
• Promote Inter-State and Inter-Agency Coordination: Effective clean-air management requires stronger coordination among Central and State Governments, SPCBs, ULBs and other stakeholders, supported by transparent monitoring through platforms such as PRANA.
