What Happened
- Four Memoranda of Understanding (MoUs) were signed between the Public Works Departments (PWDs) and Urban Development Departments of NCR States (Delhi, Haryana, Uttar Pradesh, and Rajasthan), CSIR-Central Road Research Institute (CSIR-CRRI), and the School of Planning and Architecture (SPA), New Delhi.
- The MoUs were signed in the presence of the Union Environment Minister at Indira Paryavaran Bhawan, New Delhi.
- The initiative aims to implement a Standard Framework for the redevelopment of urban roads — including paving of unpaved roads, greening of pathways and sidewalks — specifically targeting road dust as a major PM10 contributor in the NCR.
- A Web-GIS based Road Asset Management System (RAMS) will be implemented for systematic road condition monitoring and maintenance scheduling.
- The first phase targets nine highly urbanised NCR cities: Delhi, Faridabad, Gurugram, Sonipat, Ghaziabad, Noida, Greater Noida, Bhiwadi, and Neemrana.

Commission for Air Quality Management (CAQM) — Statutory Body for NCR Air Pollution
The Commission for Air Quality Management in National Capital Region and Adjoining Areas (CAQM) was established under the CAQM Act, 2021 — enacted to replace the earlier Environment Pollution (Prevention and Control) Authority (EPCA), which was a non-statutory body. CAQM is a statutory commission with overriding powers over state governments, Central Pollution Control Board (CPCB), and State Pollution Control Boards in the NCR and adjoining areas on air quality matters.
- Established under: The Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021
- Jurisdiction: National Capital Region + adjoining areas in Haryana, Punjab, Uttar Pradesh, and Rajasthan that affect NCR air quality
- Key power: CAQM's directions override those of state governments, CPCB, and SPCBs — sole authority on air quality in its jurisdiction
- Composition: Chairperson (senior IAS/equivalent) + full-time members (Joint Secretary level) + technical members + NGO representatives
- Functions: Coordinate state governments on anti-pollution measures, research, preparing action plans (stubble burning, dust management, industrial pollution), issue binding directions
- EPCA (predecessor): Created by Supreme Court orders in 1998 (M.C. Mehta v. Union of India); CAQM replaced it with statutory backing in 2021
Connection to this news: CAQM initiated this Standard Framework MoU as part of its mandate to reduce road dust pollution — road dust (unpaved roads, construction sites) is estimated to contribute 30-40% of PM10 in Delhi-NCR, making it a priority intervention area.
Road Dust and Air Pollution — PM10 and NAAQS Framework
Particulate Matter (PM) is classified by aerodynamic diameter: PM2.5 (≤2.5 μm, fine particles — penetrate deep into lungs) and PM10 (≤10 μm, coarse particles — includes road dust, construction dust). Road dust is a major contributor to PM10 in Indian cities, generated by vehicle movement on unpaved/poorly paved roads, re-suspension of deposited particulates, and construction debris.
- National Ambient Air Quality Standards (NAAQS): Set by CPCB under Environment (Protection) Act, 1986; PM2.5 annual standard: 40 μg/m³; PM10 annual standard: 60 μg/m³
- Delhi's average PM10: Consistently exceeds 100 μg/m³ (annual); during winter peaks can reach 500+ μg/m³
- Graded Response Action Plan (GRAP): CAQM-enforced system of escalating restrictions (Stage I-IV) based on AQI levels in Delhi-NCR; Stage IV (AQI >450) triggers school closures, construction bans, vehicle restrictions
- Road dust sources: Unpaved shoulders, poorly maintained roads, open areas — addressed by the Standard Framework through mandatory paving and greening of road rights-of-way
- Air (Prevention and Control of Pollution) Act, 1981: Primary law for air quality management; establishes CPCB and SPCBs; NAAQS set under this Act
Connection to this news: The Standard Framework targets road dust specifically — through cross-section design for different road types, mandatory greening of road rights-of-way, and Web-GIS based monitoring. This directly addresses PM10 reduction in Delhi-NCR.
CSIR-CRRI and Road Engineering Research in India
The Central Road Research Institute (CRRI), established in 1952 under the Council of Scientific and Industrial Research (CSIR), is India's premier research institution for road transportation engineering. It provides technical expertise on road design standards, construction materials, pavement engineering, and traffic safety.
- CSIR-CRRI: Established 1952; located in New Delhi; under CSIR (Council of Scientific and Industrial Research, DSIR) — a body of national research laboratories under the Ministry of Science and Technology
- Key technical contributions: IRC (Indian Roads Congress) standards for road construction; bituminous pavement design; road safety audits; geotechnical investigations
- Road Asset Management System (RAMS): A systematic approach to road condition assessment, deterioration modelling, and maintenance prioritisation — CSIR-CRRI provides technical expertise for Web-GIS based RAMS implementation
- School of Planning and Architecture (SPA): Premier architecture and planning institution (Institute of National Importance); expertise in urban design and sustainable planning — contributes to greening and walkability aspects of the Standard Framework
Connection to this news: CSIR-CRRI's domain expertise in road engineering and SPA's urban planning capacity are being leveraged through the MoUs to provide technical backbone for the Standard Framework implementation across NCR states.
Environmental Governance for Delhi-NCR — Institutional Framework
Delhi-NCR's environmental governance involves a complex multi-stakeholder structure: the Union Government (MoEFCC), CAQM (for air quality), CPCB (national standards body), Delhi Pollution Control Committee (DPCC), State PCBs of Haryana, UP, Rajasthan, and Punjab, plus city-specific bodies (PWDs, MCDs). The CAQM Act, 2021 attempted to resolve coordination failures by giving CAQM overriding authority.
- Indira Paryavaran Bhawan: MOEF&CC's headquartes in New Delhi — symbolic location for the MoU signing signals Environment Ministry ownership
- MoEFCC (Ministry of Environment, Forest and Climate Change): Nodal ministry for environment; Environment (Protection) Act, 1986 empowers central government to take measures for protecting and improving environment quality
- NGT (National Green Tribunal): Quasi-judicial body established under National Green Tribunal Act, 2010 — has jurisdiction over all environment-related disputes; has taken up numerous Delhi air quality cases
- GRAP (Graded Response Action Plan): CAQM-operationalised; originally developed under EPCA; now legally mandated under CAQM framework
- National Clean Air Programme (NCAP): Launched 2019; targets 20-30% reduction in PM2.5 and PM10 concentrations by 2024 (base year 2017) in 131 non-attainment cities including Delhi
Connection to this news: The road dust MoU is one intervention within the broader NCAP and CAQM action plan framework — complementing measures targeting stubble burning (Punjab/Haryana), industrial emissions, and vehicular pollution as the main NCR air quality contributors.
