Quick Revision: The CAQM Act, 2021, under Section 12, empowers the Commission to issue pre-emptive directions to mitigate anticipated air quality deterioration, as demonstrated by the recent 15-day construction ban and 50% work-from-home mandate in Delhi-NCR.

Why is this in the news?

The Commission for Air Quality Management (CAQM) in the National Capital Region (NCR) and Adjoining Areas issued a 15-day ban on dust-generating demolition and outdoor construction activities, alongside a 50% work-from-home mandate in Delhi and five NCR districts. This pre-emptive measure, issued under Section 12 of the CAQM Act, 2021, marks a departure from the reactive approach of the Graded Response Action Plan (GRAP), aiming to mitigate anticipated air quality deterioration due to meteorological conditions, stubble burning, and Diwali-related firecracker emissions.

Background

• The Delhi-NCR region experiences severe air pollution annually, particularly during the post-monsoon and winter months, due to a confluence of anthropogenic and meteorological factors.
• The Graded Response Action Plan (GRAP) was introduced in 2017 as a set of emergency measures to combat air pollution, triggered by real-time deterioration in air quality or forecasted deterioration.
• The CAQM was established in 2021 under the Commission for Air Quality Management (CAQM) Act to oversee air quality management in the NCR and adjoining areas, replacing the erstwhile Environment Pollution (Prevention and Control) Authority (EPCA).
• Stubble burning in Punjab and Haryana post-monsoon contributes significantly to the transboundary transport of particulate matter into the NCR.
• Meteorological conditions such as temperature inversions, low wind speeds, and reduced precipitation during winter exacerbate the accumulation of pollutants in the region.
• Diwali celebrations, marked by firecracker emissions, have historically led to sharp spikes in particulate matter concentrations in the NCR.

What is the Commission for Air Quality Management (CAQM) Act, 2021, and its role in air quality management?

• The CAQM Act, 2021, was enacted to establish the Commission for Air Quality Management (CAQM) as a statutory body with jurisdiction over the National Capital Region (NCR) and adjoining areas, including parts of Punjab, Haryana, Rajasthan, and Uttar Pradesh.
• The Act empowers the CAQM to take all necessary measures to protect and improve air quality, including issuing directions to state governments, local bodies, and other agencies.
• Section 12 of the Act grants the CAQM the authority to issue directions it deems necessary or expedient for preventing, controlling, and abating air pollution, even in anticipation of deterioration.
• The CAQM is mandated to develop and implement programmes and strategies for air quality management, including the Graded Response Action Plan (GRAP) and other preventive measures.
• The Act provides for the establishment of a multi-state, multi-sectoral institutional framework to ensure coordinated action across jurisdictions.
• The CAQM also monitors and reviews the implementation of air quality improvement measures and conducts research on air pollution sources and mitigation strategies.
• The Act includes provisions for penalties and enforcement mechanisms to ensure compliance with its directives.

Challenges — UPSC Perspective

Issue	Concern
Stubble burning in Punjab and Haryana	Contributes ~30-40% of Delhi’s PM2.5 during peak winter months, exacerbating air quality deterioration.
Meteorological stagnation (temperature inversions)	Traps pollutants near ground level, reducing dispersion and worsening AQI despite emission controls.
Diwali firecracker emissions	Can cause AQI to spike from ‘Moderate’ to ‘Severe’ within hours, overwhelming short-term mitigation efforts.
Construction and demolition activities	Release coarse and fine particulate matter, directly contributing to ambient PM levels.
Vehicular emissions in NCR	Account for ~20-25% of PM2.5, with diesel vehicles and older cars being major contributors.
Limited enforcement capacity of local bodies	Hinders effective implementation of construction bans and work-from-home mandates, reducing policy efficacy.

Way Forward

• Enhance real-time air quality monitoring networks with hyperlocal data dissemination to inform adaptive policy responses.
• Expand mechanised stubble management programmes (e.g., Happy Seeders, bio-decomposers) with farmer-centric incentives and subsidies.
• Implement staggered vehicular entry timings and congestion pricing in NCR to reduce peak-hour emissions.
• Strengthen public awareness campaigns on air pollution impacts and mitigation measures, including Diwali alternatives.
• Develop inter-state coordination mechanisms for stubble burning monitoring, using satellite data and field verification.
• Invest in green construction materials and dust suppression technologies to minimise construction-related PM emissions.
• Establish a dedicated grievance redressal system for pollution violations, with penalties calibrated to economic deterrence.
• Integrate air quality forecasts into urban planning, ensuring that development projects account for seasonal pollution risks.

– Contrast with GRAP’s reactive nature under the Air (Prevention and Control of Pollution) Act, 1981, and the National Clean Air Programme (NCAP).
– Discuss the constitutional underpinnings: Entry 14 (air pollution) and Entry 17 (water pollution) of the State List (7th Schedule), and the role of the Union Government in inter-state coordination.

2. **Institutional Framework**:
– Role of the CAQM as a statutory, multi-state body with representatives from the Centre, states, and domain experts.
– Coordination challenges: Need for alignment between CAQM orders, state-level pollution control boards, and municipal authorities (e.g., NDMC, MCD).
– Cite the example of Chief Secretaries and District Magistrates coordinating enforcement in the NCR.

3. **Environmental and Meteorological Context**:
– Explain the role of meteorological conditions (temperature inversion, wind patterns) in exacerbating air pollution during winter.
– Link to stubble burning in Punjab and Haryana, and the need for pre-emptive measures given the 55–60% paddy harvesting completion.
– Reference the Diwali festival and firecracker emissions as additional factors.

4. **Challenges in Enforcement**:
– Implementation gaps: Construction and demolition bans, work-from-home mandates, and vehicle entry restrictions require strong ground-level enforcement.
– Economic and social costs: Impact on construction sector, commuters, and daily wage workers.
– Public compliance: Need for awareness campaigns and incentives for adherence.

5. **Long-Term Implications**:
– Potential for CAQM to institutionalise pre-emptive action as a standard practice, reducing reliance on reactive GRAP measures.
– Role in strengthening inter-state cooperation under the NCAP and SDG 11 (Sustainable Cities and Communities).
– Lessons for other polluted regions (e.g., Mumbai, Kolkata) in adopting anticipatory governance.

6. **Balancing Views**:
– Support: Pre-emptive measures can prevent severe air quality degradation and public health crises.
– Criticism: Over-reliance on executive action without legislative backing or parliamentary scrutiny may raise federalism concerns.
