Bureau of Energy Efficiency (BEE) Revised Fuel-Efficiency Norms
Introduction
The BEE has revised its draft fuel-efficiency norms effective June 2024, offering relief for small cars and incentives for flex-fuel and strong hybrid vehicles.
Background
- Maruti Suzuki requested special relief for small cars under the CAFE-3 and CAFE-4 norms.
- Opposition from other manufacturers like Tata Motors and Mahindra & Mahindra.
- CAFE norms set targets for carbon-dioxide emissions measured in gm/km.
Revised Draft Highlights
- Classification of Small Cars: First-time separate classification for small cars weighing up to 909 kg, engine capacity ≤ 1,200 cc, and length ≤ 4,000 mm.
- Special Treatment for Small Cars:
- Eligible for an extra reduction of 3 gm/km in declared emissions.
- Cumulative reduction capped at 9 g/km of CO₂.
Volume Derogation Factor
- Multiplier for fleet carbon-dioxide calculations.
- Factor for EVs maintained at three, strong hybrids at two, benefiting companies like Maruti Suzuki and Toyota.
Carbon Neutrality Factor (CNF)
- Introduced for vehicles using cleaner fuels or hybrid technology.
- Discounts:
- E20-E30 petrol: 8%
- CNG: 5% or higher
- Flex-fuel ethanol & strong hybrids: 22.3%
Implementation and Feedback
Stakeholders have 21 days to respond to the draft norms. No immediate response from major carmakers was reported.
Conclusion
- Full volume derogation factor of 2 retained for strong hybrids.
- Flex-fuel and strong hybrid cars get 22.3% lower CO2 under CNF.
