India has introduced the third phase of Corporate Average Fuel Economy (CAFE-3) norms for passenger vehicles. The new framework will apply from April 1, 2027, to March 31, 2032, and aims to improve vehicle fuel efficiency and reduce carbon emissions. However, while the framework offers several incentives for cleaner technologies, concerns have been raised that multiple compliance options could let manufacturers meet the targets without making a major shift to electric vehicles (EVs).
Why in the News?
On September 30, 2026, the Centre notified the CAFE-3 carbon emission norms for passenger vehicles. The norms gradually tighten the fleet fuel-consumption target and provide additional benefits for EVs, hybrids, ethanol-based vehicles and other fuel-efficiency technologies. CAFE-3 norms are stricter fuel-efficiency and carbon-emission standards for Indian automakers, requiring them to reduce average CO₂ emissions across passenger vehicles from April 1, 2027.
What is the CAFE-3 Framework?
CAFE-3 sets limits on the average fuel consumption and carbon emissions of a manufacturer's passenger-vehicle fleet. It will apply to new passenger vehicles manufactured or imported for sale in India. The framework will become progressively stricter during the five years.
- Validity: April 1, 2027 to March 31, 2032.
- The fleet fuel-consumption benchmark will improve from 3.996 litres/100 km in 2027-28 to 3.3273 litres/100 km in 2031-32.
- This represents an improvement of around 16.7% over five years.
- The reference vehicle weight has been fixed at 1,229 kg.
- The earlier concession for small cars weighing up to 909 kg has been removed.
- Fuel consumption will be calculated using the Modified Indian Driving Cycle (MIDC).
- Results are expressed in petrol-equivalent litres per 100 km.
Manufacturers can also earn, carry forward and trade CAFE credits during a compliance block. Manufacturers may offset deficits by purchasing credits from the Bureau of Energy Efficiency (BEE), subject to the prescribed rules.
Incentives for Alternative Technologies
CAFE-3 gives additional weight to cleaner vehicle technologies while calculating a manufacturer's fleet average. This means some vehicles are counted as more than one vehicle for compliance purposes. This system is intended to encourage manufacturers to introduce cleaner technologies while helping them meet fleet-level efficiency requirements.
| Technology | CAFE-3 Weight |
|---|
| Battery Electric Vehicle (BEV) | 3 vehicles |
| Range-Extended EV | 3 vehicles |
| Plug-in Hybrid / Flex-Fuel Strong Hybrid | 2.5 vehicles |
| Strong Hybrid | 1.6 vehicles |
| Flex-Fuel Ethanol Vehicle | 1.1 vehicles |
Carbon Neutrality Benefits
The framework also provides Carbon Neutrality Factors for vehicles using ethanol and biofuels. These reduce the emissions considered for compliance purposes.
- E20 or higher ethanol-blended petrol: 8% reduction in declared CO₂ emissions.
- Flex-fuel ethanol vehicles: 22.3% reduction.
- CNG vehicles: 5% reduction or the notified CBG blending percentage, whichever is higher.
- Diesel vehicles: reduction based on the actual biofuel-blending percentage.
These provisions allow manufacturers to gain compliance benefits from greater use of alternative fuels.
Credits for Fuel-Efficiency Technologies
Manufacturers can also receive emission reductions for certain fuel-saving technologies.
Eligible technologies include:
- Start-stop systems
- Tyre-pressure monitoring
- Regenerative braking
- Efficient alternators
- LED lighting
- Electric water pumps
A manufacturer can claim a reduction of 1 g CO₂/km for each eligible technology, subject to an overall maximum benefit of 9 g CO₂/km. Claims under the first compliance block can be self-declared, while claims under the second block will require validated test results.
Why is CAFE-3 Being Called a Missed Opportunity?
The main criticism is that CAFE-3 provides manufacturers with multiple ways to meet the efficiency targets. This could reduce the pressure to rapidly increase EV sales. Former NITI Aayog CEO Amitabh Kant argued that the norms could have been used to accelerate India's transition towards electric mobility. He said that EVs should be the long-term direction of the automobile sector rather than simply one option among several compliance pathways.
According to Amit Bhatt, India Managing Director of the International Council on Clean Transportation, the final framework could allow manufacturers to meet the targets largely through existing technologies.
- Industry commitments indicate around 20% EV sales by 2030.
- According to the analysis cited in the article, CAFE-3 could potentially be met with around 12% EV uptake by 2032.
- This creates a gap between the industry's voluntary EV commitments and the level of EV adoption potentially required under the regulation.
The concern is that super credits and technology credits, while useful for supporting emerging technologies, may have a weaker effect when extended to technologies that are already widely available.
Super Credits and Compliance Pathways
The super-credit system gives additional weight to cleaner vehicles such as EVs. It can help manufacturers introduce new technologies and increase their market share. However, the article argues that extending similar benefits to several established technologies could dilute the incentive for faster electrification to meet the overall target without making a major shift towards EVs. The key concern is that manufacturers may be able to combine:
- EV credits,
- hybrid vehicle credits,
- ethanol and biofuel benefits,
- fuel-efficiency technology credits, and
- CAFE credit trading
CAFE-3 and Global Trends
The global trend is towards stricter vehicle-emission standards and greater electrification.
European Union
The EU has adopted progressively tighter fleet CO₂ targets.
- 93.6 g CO₂/km for new cars during 2025–29.
- 49.5 g CO₂/km from 2030.
- Existing legislation targets a 100% reduction from 2035.
China
China's long-term industrial policy aims for New Energy Vehicles (NEVs) to account for around 70% of domestic new passenger-vehicle sales by 2030.
These approaches indicate a stronger regulatory push towards vehicle electrification.
Role of WLTP
The transition to the Worldwide Harmonised Light Vehicles Test Procedure (WLTP) could provide an opportunity to reassess India's vehicle-emission framework. WLTP is a standardised method for measuring:
- Fuel consumption
- CO₂ emissions
- Electric driving range
A shift towards WLTP could also help India review the balance between different compliance pathways and the incentives provided to various technologies.
Conclusion
CAFE-3 strengthens India's vehicle-efficiency requirements and provides incentives for EVs, hybrids, ethanol, biofuels and fuel-saving technologies. However, the large number of compliance pathways may reduce the pressure on manufacturers to rapidly increase EV adoption. The central policy challenge is to balance technology neutrality with the need for a clear long-term transition towards low-carbon and electric mobility.
