India’s electric vehicle (EV) transition, propelled by schemes such as the Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME) programme and an array of State-level subsidies, has achieved notable success in new-vehicle sales, with EVs now accounting for 8.5 per cent of total new vehicle sales in FY26, according to VAHAN database figures. Yet, as a recent Hindu Data Point analysis by Jaideep Saraswat and Ashish Dokania argues, this transition risks leaving behind a comprehensive retrofitment framework, without which India’s circular mobility economy and its climate commitments remain incomplete.
Retrofitment — the conversion of existing internal combustion engine (ICE) vehicles to run on electric power — represents an under-utilised lever in India’s decarbonisation strategy. While the policy conversation has focused overwhelmingly on incentivising the purchase of new EVs, the vast installed base of ICE vehicles on Indian roads, particularly two- and three-wheelers used by lower and middle-income households, remains largely excluded from India’s EV policy architecture. This is a critical omission because buying a new EV is often technically and economically out of reach for many households that would otherwise benefit from switching to electric mobility.

For UPSC and SSC aspirants, this topic bridges environment and climate policy, industrial policy, urban transport planning and social equity — themes central to GS Paper III (environment, infrastructure, energy) and GS Paper II (government policies and interventions). It is also a good example of how India’s climate commitments under the Paris Agreement and its Nationally Determined Contributions (NDCs) translate into ground-level, sector-specific policy debates involving cost, technology and equity trade-offs.
Background and Context
Over the past decade, India has placed enormous emphasis on transport decarbonisation through multiple, sometimes overlapping, subsidy schemes rolled out under FAME and various State EV policies. These have primarily incentivised new-vehicle purchases through upfront subsidies, in the belief that this would create sustained ecosystem demand. As a result, EV sales have grown steadily, with two-wheelers, three-wheelers and four-wheelers all posting healthy year-on-year increases since 2016-17. However, retrofitting existing ICE vehicles remains more a technical and economic possibility than a mainstream reality in India, largely due to regulatory ambiguity, safety and reliability concerns, and a weak certification ecosystem.
Five Important Key Points
- EV sales reached 8.5 per cent of total new vehicle sales in FY26, based on VAHAN database figures, marking significant growth from near-zero levels in 2016-17.
- Petrol and diesel vehicles continue to dominate India’s registered vehicle stock, accounting for 38.1 crore vehicles compared to only 0.95 crore EVs and 0.19 crore hybrids as of the data compiled.
- Middle-income households in India still find buying a new EV unaffordable, so scrap value retention through retrofitment is being increasingly recognised as a viable alternative pathway.
- Some Indian States have begun taking steps toward building a favourable retrofit policy ecosystem for EVs, though a comprehensive national retrofitment framework does not yet exist.
- The four-wheeler segment shows petrol, diesel and hybrid vehicles making up the overwhelming majority of registrations, with EVs still comprising only a small single-digit share.
The Case for Retrofitment as a Climate and Equity Tool
Retrofitment addresses a structural gap in India’s decarbonisation strategy: replacing existing ICE vehicles entirely through natural attrition would take considerably longer than converting a share of the installed base directly. Since retrofitting avoids the resource-intensive process of manufacturing an entirely new vehicle, it also reduces embedded carbon emissions associated with vehicle production, pointing to a more circular mobility economy that maximises the useful life of existing assets rather than discarding them prematurely.
Regulatory Framework and Certification Gaps
India currently lacks a robust national regulatory framework for retrofitting internal combustion engine vehicles into electric ones. Certified retrofit companies exist but operate alongside unregulated, informal players offering unsafe or unreliable conversions, raising real-world risks such as inadequate battery management, fire safety and structural integrity concerns. Fourth, Goods and Services Tax (GST) treatment may be rationalised, since retrofitted vehicles are not taxed on par with new EVs currently, creating a disadvantage even where a genuine environmental benefit exists. Unlike new EVs, which benefit from clear GST concessions, retrofitted vehicles can face ambiguous or unfavourable tax treatment, undermining the economics of conversion.
Economic and Market Dimensions
Retrofitting offers a substantially lower-cost pathway to electrification for two- and three-wheeler owners, who form the backbone of last-mile and informal transport across Indian cities. Since two-wheelers and three-wheelers are not shown separately in truck data but dominate India’s vehicle stock numerically, targeted retrofit subsidies for this segment could deliver outsized emissions reductions per rupee spent compared to subsidising new four-wheeler EV purchases, which disproportionately benefit wealthier households.
Governance Concerns and State-Level Fragmentation
Even as some States have begun developing retrofit-friendly regulations, the absence of a uniform national standard creates fragmentation, discouraging retrofit companies from scaling operations across State lines. This mirrors broader challenges in India’s cooperative federalism around environmental and transport policy, where State-level initiative often outpaces central coordination, leading to inconsistent standards and consumer protection gaps.
Comparative Global Examples
Countries across Europe have pursued circular mobility strategies that explicitly incorporate retrofitting alongside new EV incentives, recognising that manufacturing capacity constraints and affordability concerns mean new-vehicle transitions alone cannot meet climate targets fast enough. India, given its vast installed base of low-cost two- and three-wheelers, has an opportunity to try distinct approaches between retrofitting existing vehicles and scrapping or recycling them under expanded vehicle scrappage policies, rather than treating these as mutually exclusive strategies.
Way Forward
India needs a comprehensive national retrofitment policy framework that includes clear legal recognition of retrofitted vehicles across State Regional Transport Offices (RTOs), mandatory safety and reliability standards to eliminate unauthorised or unsafe conversions, and rationalised GST treatment that does not disadvantage retrofitting relative to new EV purchases. Targeted retrofit subsidies focused on two- and three-wheelers, integrated with the existing vehicle scrappage policy, would maximise both emissions reductions and social equity outcomes.
