New CAFE-III Norms Proposed for Passenger Vehicles: Key Details
UPSC / SSC current affairs note · IR
Why in news
The Ministry of Power has released the draft CAFE-III norms, proposing stricter fuel-efficiency standards for passenger vehicles from April 1, 2027. This move is significant as it sets a clear roadmap for automakers to develop more fuel-efficient models and recognizes alternative fuels like ethanol and biogas as carbon-neutral.
Background
CAFE norms were introduced in India to improve fuel efficiency and reduce CO2 emissions from passenger vehicles. The current CAFE-II norms are in force until March 31, 2027. CAFE-III will replace them with more stringent targets.
Key facts
CAFE-III norms apply to M1 category passenger vehicles (up to 8 seats, excluding driver) manufactured or imported in India from FY2027-28 to FY2031-32.
Fuel consumption target reduces from 3.996 litres/100 km (94.76 gCO₂/km) in FY2027-28 to 3.3273 litres/100 km (78.90 gCO₂/km) by FY2031-32.
Compliance assessed in two phases: first block of 3 years, second block of 2 years.
Alternative fuels (ethanol, bio-fuels, CBG) get carbon neutrality recognition: 8% Carbon Neutrality Factor for current ethanol blends; CBG reduction depends on blending levels.
Manufacturers can claim compliance benefits up to 9 gCO₂/km for fuel-saving technologies, capped at 1 gCO₂/km per technology.
Draft released for public consultation until August 6, 2026.
Prelims pointers
- CAFE: Corporate Average Fuel Economy
- Ministry of Power (not Environment) is the nodal ministry for CAFE norms
- M1 category: passenger vehicles with up to 8 seats (excluding driver)
- CAFE-III proposed to start from April 1, 2027
- Carbon Neutrality Factor (CNF) for alternative fuels
- Compliance benefits capped at 1 gCO₂/km per technology, total up to 9 gCO₂/km
Mains angles
- Discuss the significance of CAFE-III norms in India's climate commitments and fuel efficiency goals.
- Critically examine the impact of CAFE-III on the Indian automobile industry and transition to cleaner technologies.
- Analyze the role of alternative fuels and carbon neutrality recognition in reducing vehicular emissions.
