Introduction

India is the world’s third-largest carbon emitter, and the transport sector plays a significant role in this trajectory. It contributes nearly 10% of India’s total greenhouse gas (GHG) emissions (excluding land-use and forestry) and about 12–14% of energy-related CO₂ emissions, making it a key target for decarbonisation. Vehicular emissions are also a major cause of deteriorating air quality in Indian cities, many of which rank among the most polluted globally. Reducing transport emissions is therefore not just an environmental imperative but also a public health and economic necessity.

To address this challenge, India has adopted a multi-pronged approach that includes promoting ethanol blending, expanding electric mobility, tightening emission norms, and introducing a vehicle scrappage policy to phase out older vehicles. These initiatives reflect the government’s attempt to balance environmental goals with economic growth and energy security. At the same time, questions remain about their effectiveness, long-term sustainability, and impact on consumers and farmers. As India experiments with different technological pathways, from biofuels to electric vehicles, its vehicle policy is still evolving. The following sections will examine these strategies in detail, highlighting their significance, challenges, and the road ahead.


Vehicle Policy in India

Vehicle policy in India is primarily shaped by the Union Government, with major responsibility lying with the:

  • Ministry of Road Transport and Highways (MoRTH): Drafts and enforces vehicle emission and fuel efficiency norms under the Motor Vehicles Act.

  • Ministry of Environment, Forest and Climate Change (MoEFCC): Frames environmental standards (through the CPCB) under the Environment Protection Act, 1986.

  • NITI Aayog: Provides policy direction for electric mobility, ethanol blending, and alternative fuels.

  • Ministry of Petroleum and Natural Gas (MoPNG): Oversees fuel quality and ethanol blending targets.

  • State Governments & Transport Departments: Implement and enforce vehicle rules, registration, and scrappage at the local level.


Evolution of Vehicle Policy in India

India’s vehicle emission control framework has evolved in phases, responding to changing economic, environmental, and social needs:

  • Post-Independence (1947–1980s):

    • Focus on building an indigenous automobile industry under the License Raj.

    • Policy concerns were limited to production and regulation; emissions were not a priority.

    • Low vehicle ownership meant limited attention to urban air quality.

  • Initial Emission Norms (1990s):

    • First emission standards introduced in 1991 (petrol vehicles) and 1992 (diesel vehicles).

    • Growing urban air pollution led to judicial interventions — the Supreme Court mandated CNG use in Delhi’s buses and autos (1998–2001).

    • Public transport and fuel-switching policies began to gain traction.

  • Bharat Stage (BS) Norms (2000 onwards):

    • Adoption of BS norms in 2000, modelled on Euro standards.

    • BS-II (2005), BS-III (2010), BS-IV (2017).

    • Landmark move: skipping BS-V to directly implement BS-VI in April 2020, cutting particulate matter and NOx emissions drastically.

  • Corporate Average Fuel Efficiency (CAFE) Norms (2017 onwards):

    • Introduced to improve fleet-level fuel efficiency of automakers.

    • Aimed at reducing carbon intensity and fuel consumption in line with global practices.

Conclusion

India’s transport sector is at a critical juncture, balancing short-term measures like ethanol blending with long-term strategies centered on electric mobility. Ethanol has delivered significant economic benefits, strengthened farmer incomes, and reduced crude oil imports. However, challenges such as water stress, food security concerns, and consumer resistance highlight the need for diversified feedstocks and balanced fuel policies. Electric mobility, though currently slower in adoption due to high costs, infrastructure gaps, and REE dependence, promises far greater emissions reductions and sustainable urban air quality improvement. A phased approach using hybrids as transitional technology, expanding domestic manufacturing, and promoting charging infrastructure is essential.

An integrated strategy that combines ethanol and EV policies, supported by global best practices and domestic incentives, will enable India to advance toward cleaner, energy-secure, and resilient transport. Achieving 30% EV sales by 2030, promoting advanced biofuels, and building a self-reliant EV ecosystem will be crucial for meeting the country’s Net Zero 2070 commitment.
