Government Proposes Global Testing Standards, Tougher Carbon Targets, and Stronger Incentives for Electric and Hydrogen Vehicles to Reduce Oil Dependence

The Government of India has unveiled the draft Corporate Average Fuel Efficiency (CAFE)-III norms, proposing a comprehensive overhaul of the country's fuel-efficiency framework for passenger vehicles. Released by the Bureau of Energy Efficiency (BEE) for public consultation, the new regulations are designed to reduce fuel consumption, lower carbon emissions, and accelerate India's transition toward cleaner and more sustainable mobility.

The proposed CAFE-III norms will be applicable to passenger vehicles manufactured between FY2027-28 and FY2031-32, replacing the current CAFE-II regime. The draft introduces several structural changes, including the adoption of the globally accepted Worldwide Harmonised Light Vehicles Test Procedure (WLTP), stricter fleet-wide carbon emission targets, revised incentives for electric and hydrogen-powered vehicles, and a longer compliance cycle for manufacturers.

The move comes as India continues to balance rapid growth in vehicle ownership with its climate commitments, energy security goals, and efforts to reduce dependence on imported crude oil. With the automobile industry investing heavily in electric mobility, hybrid technologies, and cleaner internal combustion engines, the proposed regulations are expected to influence product development, investment decisions, and consumer choices over the next decade.

Understanding Corporate Average Fuel Efficiency (CAFE) Norms

Corporate Average Fuel Efficiency (CAFE) norms are regulations that establish the average fuel-efficiency target an automobile manufacturer must achieve across all passenger vehicles sold during a financial year.

Unlike emission standards that apply to individual vehicle models, CAFE evaluates the combined performance of a manufacturer's entire fleet. This allows companies to sell larger SUVs or premium vehicles provided they offset higher emissions with more fuel-efficient, hybrid, or electric models.

The framework aims to:

• Improve average fuel efficiency.

• Reduce carbon dioxide emissions.

• Lower fossil fuel consumption.

• Encourage technological innovation.

• Improve urban air quality.

• Strengthen India's long-term energy security.

The Bureau of Energy Efficiency administers the programme under the Energy Conservation Act.

India's Fuel-Efficiency Journey

India introduced CAFE regulations in phases to give automakers time to adapt to evolving environmental standards.

CAFE-I (FY2017-18)

The first phase introduced fleet-average fuel-efficiency requirements for passenger vehicles.

CAFE-II (FY2022-23)

The second phase tightened emission limits while expanding the framework to include petrol, diesel, CNG, LPG, hybrid, and electric passenger vehicles weighing up to 3,500 kilograms.

CAFE-III (Proposed)

The third phase focuses on aligning India's regulations with international standards while significantly strengthening carbon reduction targets.

Key Changes Proposed Under CAFE-III

The draft proposes a series of major reforms that go beyond simply lowering emission limits.

Transition to WLTP Testing

The most significant change is the replacement of the Modified Indian Driving Cycle (MIDC) with the Worldwide Harmonised Light Vehicles Test Procedure (WLTP).

WLTP is considered more accurate because it:

• Better reflects real-world driving conditions.

• Measures fuel consumption more realistically.

• Provides internationally comparable results.

• Is already adopted across Europe and several global markets.

The new testing standard is proposed to become mandatory for vehicle certification from March 31, 2027.

Stricter Carbon Emission Targets

The government has proposed reducing the fleet-average carbon dioxide emission target to:

91.7 grams of CO₂ per kilometre during the CAFE-III period.

Looking ahead, the draft proposes an even stricter target of:

70 grams of CO₂ per kilometre under the future CAFE-IV framework covering 2032–2037.

The phased approach is intended to encourage continuous technological advancement without creating abrupt disruptions for manufacturers.

Five-Year Compliance Framework

The draft introduces a new five-year compliance structure.

Instead of shorter evaluation periods, manufacturers will now operate under:

• One compliance block covering FY2027–2032.

• Annual reporting of performance.

• Compliance assessed across the entire five-year period.

• Greater flexibility in planning future vehicle launches.

The framework enables automakers to strategically balance their product portfolios over several years.

Revised Super Credits for Low-Emission Vehicles

The government has proposed significant revisions to the super-credit mechanism used to calculate fleet-average emissions.

Proposed multipliers include:

The revised incentive structure clearly prioritizes zero-emission vehicles over transitional technologies.

Updated Technology Credits

Manufacturers introducing technologies that improve vehicle efficiency will continue receiving additional compliance credits.

Eligible technologies include:

• Regenerative braking systems.

• Automatic engine start-stop technology.

• Six-speed and higher transmissions.

• Advanced energy management systems.

• Carbon-reduction technologies.

The government is also studying additional incentives for ethanol-compatible vehicles.

Why Is India Tightening Fuel-Efficiency Standards?

India remains one of the world's largest importers of crude oil.

Improving vehicle fuel efficiency helps the country:

• Reduce petroleum imports.

• Strengthen energy security.

• Lower greenhouse gas emissions.

• Improve urban air quality.

• Meet international climate commitments.

• Reduce long-term fuel expenses for consumers.

Road transport accounts for a substantial share of India's petroleum consumption, making improved vehicle efficiency a strategic national objective.

Impact on Automobile Manufacturers

The proposed regulations are expected to reshape the Indian automotive industry.

Manufacturers may need to:

• Expand electric vehicle production.

• Improve internal combustion engine efficiency.
