Draft CAFE-III Norms
Why in News?
The Government of India released the draft Corporate Average Fuel Economy (CAFE)-III norms on 16 July 2026, proposing stricter fuel-efficiency standards for M1 category passenger vehicles manufactured or imported for sale in India during 2027-28 to 2031-32. The draft has been issued for public consultation and aims to reduce fuel consumption, lower carbon emissions, and promote cleaner vehicle technologies in line with India’s climate commitments.
What are Corporate Average Fuel Economy (CAFE) Norms?
The Corporate Average Fuel Economy (CAFE) framework is a regulatory mechanism that prescribes the average fuel-efficiency standards that automobile manufacturers must achieve across their fleet of passenger vehicles. Instead of setting targets for individual vehicles, the framework evaluates the average fuel consumption and carbon dioxide (CO₂) emissions of all eligible vehicles sold by a manufacturer during a financial year.
In India, CAFE norms apply to M1 category passenger vehicles, which are motor vehicles designed to carry passengers and have not more than eight seats in addition to the driver’s seat. The proposed CAFE-III norms will succeed CAFE-II, which is scheduled to remain in force until 31 March 2027. The new standards are proposed to come into effect from 1 April 2027.
Key Provisions of Draft CAFE-III Norms
The draft proposes progressively tighter fuel-efficiency and emission standards over a five-year compliance period.
| Financial Year | Fuel Consumption Target | CO₂ Emission Target |
|---|---|---|
| 2027-28 | 3.996 litres/100 km | 94.76 gCO₂/km |
| 2031-32 | 3.3273 litres/100 km | 78.90 gCO₂/km |
The gradual reduction in permissible fuel consumption is intended to encourage manufacturers to develop more fuel-efficient internal combustion vehicles, increase the adoption of electric and alternative fuel vehicles, and invest in advanced automotive technologies.
Compliance Mechanism
One of the major features of the draft CAFE-III norms is the introduction of a market-based compliance system.
Manufacturers that fail to meet their fleet-average fuel-efficiency targets will be allowed to purchase fuel-efficiency credits either from other manufacturers with surplus credits or directly from the Bureau of Energy Efficiency (BEE). This flexible compliance mechanism is expected to reduce the overall cost of achieving national fuel-efficiency goals while encouraging technological innovation.
The proposed BEE credit buyout price starts at ₹2,500 per gram of CO₂/km in FY 2027-28 and gradually increases to ₹4,500 per gram of CO₂/km by FY 2031-32, creating stronger incentives for manufacturers to comply with the prescribed standards.
Technology Incentives
The draft also recognises the role of advanced fuel-saving technologies in improving vehicle efficiency. Manufacturers adopting approved technologies can claim compliance benefits of up to 9 gCO₂/km, subject to a maximum benefit of 1 gCO₂/km for each eligible technology.
In addition, the framework recognises the use of ethanol, biofuels, and compressed biogas (CBG) for carbon-neutrality adjustments, encouraging cleaner and renewable transportation fuels as part of India’s broader energy transition strategy.
Significance of Draft CAFE-III Norms
The proposed CAFE-III norms represent an important step towards improving India’s transport-sector energy efficiency and reducing greenhouse gas emissions. Since the transport sector accounts for a significant share of India’s petroleum consumption and urban air pollution, stricter fuel-economy standards will help reduce fuel imports, improve energy security, and support India’s commitments under the Paris Agreement and its long-term net-zero emissions pathway.
The introduction of fuel-efficiency credit trading also aligns India’s regulatory framework with global best practices by providing manufacturers with greater flexibility while maintaining environmental objectives.
