Fixing Delhi’s air quality crisis, Pg 7.

Key Highlights:

• July–August are critical months for Delhi to prepare for post-monsoon air pollution.
• Air pollution in Delhi-NCR stems from both local and transboundary sources across the Indo-Gangetic Plain (IGP).
• Implementation of pollution mitigation is impeded by fragmented governance and inconsistent regulations across states.
• The Commission for Air Quality Management (CAQM) offers a unified platform to implement regional air quality strategies.
• India is a signatory to the Malé Declaration (1998), encouraging regional collaboration on transboundary air pollution.
• Current political alignment among Delhi-NCR states presents a strategic window for coordinated action.
• Key mitigation includes biomass reduction, cleaner industrial fuels, and freight emission control.

Detailed Insights:

• Delhi’s pollution crisis worsens in autumn and winter, requiring preemptive regional action in July–August.
• Emission sources span household biomass, freight transport, brick kilns, and industrial fuels, with commonalities across IGP states.
• Fragmented institutional frameworks (e.g., multiple road-owning agencies in Delhi, differing vehicle/fuel rules) dilute the impact of isolated efforts.
• Despite international commitments (e.g., Stockholm Declaration, Rio Declaration), India lacks legal enforcement for regional pollution control.
• The Malé Declaration can serve as a framework to enable joint action plans, emission targets, and scientific cooperation.
• CAQM, empowered under parliamentary legislation, can help synchronize state-level measures and implement region-wide clean air strategies.
• The current electoral alignment across Delhi, UP, Haryana, and Rajasthan enhances the feasibility of joint mandates and coordinated targets.
• The Indo-Gangetic Plain’s transboundary dynamics (e.g., inter-state freight, shared pollution sources) necessitate a regional strategy over siloed interventions.

Concepts Involved:

• Transboundary Pollution: Pollution that originates in one region and crosses boundaries due to atmospheric movement.
• Zig-zag Kiln Technology: A cleaner brick kiln design that improves fuel efficiency and reduces particulate emissions.
• Commission for Air Quality Management (CAQM): A statutory body created in 2020 to manage air quality in NCR and adjoining areas.
• Malé Declaration (1998): A regional agreement among South Asian countries to collaborate on combating transboundary air pollution.
