Centre targets replacement of two lakh old trucks, buses in Delhi-NCR within a year

The launch of the PARIVARTAN scheme (Promoting Accelerated Replacement of Vehicles for Air Quality Improvement and Transport Transformation) marks a significant policy intervention by the Government of India to tackle the persistent air pollution crisis in the Delhi-National Capital Region (NCR). Announced in early 2024, the scheme targets the replacement of two lakh end-of-life commercial vehicles — primarily trucks and buses older than 10-15 years — within a span of one year. This initiative is not merely an environmental measure but a convergence of public health urgency, judicial mandate, and economic restructuring. The background to this scheme lies in the alarming air quality indices (AQI) that routinely plunge Delhi-NCR into the "severe" and "hazardous" categories, especially during winter months. Vehicular emissions contribute an estimated 20-40% of PM2.5 and PM10 concentrations in the region, according to studies by The Energy and Resources Institute (TERI) and IIT Kanpur. Old commercial vehicles, often compliant only with BS-II or BS-III norms, emit 10-25 times more particulate matter than BS-VI compliant vehicles. The Supreme Court, in its 2018 order in M.C. Mehta v. Union of India, had already banned the plying of 15-year-old petrol and 10-year-old diesel vehicles in Delhi-NCR. The PARIVARTAN scheme operationalizes this judicial directive by providing a financial pathway for compliance. Key stakeholders include the Ministry of Road Transport and Highways (MoRTH), the Ministry of Environment, Forest and Climate Change (MoEFCC), state governments of Delhi, Haryana, Uttar Pradesh, and Rajasthan, vehicle manufacturers, fleet operators, and financial institutions. The scheme offers a bouquet of incentives: interest subvention of up to 3-5% on loans for new BS-VI vehicles, waiver of road tax and registration fees (which can amount to 8-10% of vehicle cost), and scrappage incentives linked to the Vehicle Scrappage Policy, 2021. These measures reduce the total cost of ownership by an estimated 15-20%, making fleet renewal economically viable for small operators who constitute over 70% of the trucking sector. Constitutionally, the scheme draws legitimacy from Article 48A (Directive Principle: Protection and improvement of environment) and Article 51A(g) (Fundamental Duty: to protect and improve the natural environment). It also aligns with the Air (Prevention and Control of Pollution) Act, 1981, and the Environment (Protection) Act, 1986. The Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021, provides the institutional framework for coordinated action across states — a critical governance innovation given the transboundary nature of air pollution. Economically, the scheme stimulates demand for commercial vehicles, supporting the automotive sector which contributes 7.1% to India's GDP and employs over 37 million people. It also promotes formalization of the trucking industry, long plagued by fragmentation and informality. Socially, cleaner air translates to reduced respiratory and cardiovascular diseases — the Global Burden of Disease study attributes over 1.6 million annual deaths in India to air pollution. Broader themes include cooperative federalism (Centre-state coordination via CAQM), just transition for informal sector workers, and India's international commitments under the Paris Agreement and the UN Sustainable Development Goals (SDG 3.9, 11.6, 13). The scheme also complements the FAME-II scheme for electric mobility and the National Clean Air Programme (NCAP), which targets 40% reduction in PM10 by 2026. Future implications are profound. Success in Delhi-NCR could template similar programs for other non-attainment cities (131 identified under NCAP). Integration with the Gati Shakti master plan and the Bharatmala Pariyojana could modernize logistics. However, challenges remain: ensuring scrappage infrastructure, preventing fraud in incentive claims, addressing livelihood concerns of drivers and mechanics, and monitoring real-world emission performance. The scheme's one-year timeline is ambitious — implementation capacity, credit access for small operators, and supply chain readiness for BS-VI vehicles will determine outcomes. For aspirants, PARIVARTAN exemplifies how environmental governance in India increasingly blends regulatory stick with financial carrot, judicial push with executive pull, and local action with national framework — a template for 21st-century policy design.
