New Draft CAFE Rules

The New Draft CAFE Rules: Balancing Ambition and Feasibility

On September 29, 2025, the Ministry of Road Transport and Highways unveiled the draft Corporate Average Fuel Efficiency (CAFE) 3 norms, targeting ambitious CO₂ emission reductions across India’s passenger vehicle segment. The headline promise is clear: incentivize electric vehicles (EVs), revive the struggling small car industry, and align with global standards on vehicular emissions. Yet, what these norms have sparked is a debate not over their objective, but their feasibility.

The Policy Instrument at a Glance

CAFE norms, first introduced in 2017 under the ambit of the Bureau of Energy Efficiency, aim to regulate fuel consumption and carbon emissions from passenger vehicles weighing less than 3,500 kg. The draft CAFE 3 norms propose a multi-pronged approach:

• Efficiency Targets: Automakers now face fuel efficiency and CO₂ targets tied to the average weight of their fleet. Heavier cars benefit from relaxed standards, while lighter cars are held to stricter thresholds of up to 9 g CO₂/km lower.
• Super Credits for EVs: Electric vehicles will count as three vehicles for compliance calculations, dramatically rewarding EV adoption.
• Emission Pooling: Automakers are permitted to form pools of up to three manufacturers to collectively meet emission standards, a measure that reduces compliance costs.
• Carbon Neutrality Factor (CNF): Cars using cleaner fuels receive further relaxations on emission targets.

The draft explicitly focuses on "M1 category" passenger cars, which means SUVs, sedans, hatchbacks—essentially vehicles that dominate India's urban automotive market. It also earmarks specific breaks for small cars, aiming to alleviate the regulatory pressure on manufacturers whose smaller models have limited scope for fuel efficiency improvements.

The Case For: Why These Norms Matter

The argument in favor of CAFE 3 norms rests on both environmental urgency and industrial pragmatism. Fuel consumption among Indian vehicles has steadily increased, with the transport sector contributing approximately 12% of India’s CO₂ emissions in 2020. These norms aim to reverse that trend.

Three specific benefits deserve attention:

Environmental Outcome: The proposed super credits for EVs align with India's target of achieving 30% electric vehicle penetration by 2030 under the Faster Adoption and Manufacturing of Hybrid and Electric Vehicles (FAME) scheme. By triple-counting EV production, manufacturers gain a major incentive to invest in clean mobility options.

Revival of Small Cars: The draft’s focus on small cars signals an attempt to revive a dwindling segment. Sales of small cars have dropped from 20 million units annually in the mid-2010s to less than 13 million today. Given their affordability, small cars traditionally cater to price-sensitive markets, making their manufacturing critical for both industry sustenance and consumer welfare.

Global Alignment: The norms attempt to position India closer to global standards. The emission pooling provision mirrors industry's practices in the European Union, where companies such as BMW and Mercedes jointly meet CO₂ reduction targets—an approach that effectively balances individual compliance costs while fostering innovation.

The Case Against: Execution Risks and Institutional Skepticism

Despite the promising rhetoric, the draft CAFE 3 norms raise significant concerns when examined through the lens of execution.

First, weighted compliance targets, while designed to account for larger fleets of lightweight cars, may inadvertently incentivize manufacturers to prioritize heavier vehicles like SUVs. This is a puzzling outcome, given that SUVs consume 20-30% more fuel per km than hatchbacks.

Second, the reliance on super credits for EVs risks creating an artificial bubble. While beneficial in the short term, triple-counting EVs as compliance units could allow manufacturers to bypass necessary investment in improving fuel efficiency across their conventional engine portfolios. The EV adoption rate in India stands at a mere 2.4% of total vehicle sales—the incentive might therefore skew industry-level investment priorities.

Third, the institutional history of emissions norms in India is not reassuring. Non-compliance rates amongst leading automakers jumped to nearly 15% after the 2022 tightening of CAFE norms, even after increased penalties. The question is whether the regulatory infrastructure—particularly enforcement mechanisms—can keep pace with the ambitious provisions currently envisioned.

International Case Study: The European Union

If precedence offers lessons, look to the European Union’s emissions standards. EU norms mandate that automakers achieve fleet-wide CO₂ emissions of 95 g/km, a ceiling considerably stricter than India's limits. Companies failing the standard face fines of €95 per excess gram of CO₂ per vehicle sold.

Fleet pooling, introduced via EU regulations, has achieved mixed outcomes. While brands such as Fiat and Tesla exploited pooling to share resources and mitigate penalties, it also led to strategic gaming. Some companies optimized compliance by investing in smaller, cheaper EV models, neglecting fuel efficiency beyond baseline compliance. Similarly, the risk of stretching pooling provisions into loopholes is one policymakers in India ought to keep in mind.

Where Things Stand

Measured against its objectives, the draft CAFE 3 norms represent a necessary step forward but also risk becoming a half-measure. Deploying super credits to entice EV adoption and pooling for cost reduction offers industry relief, but may dilute the long-term goal of deeper fuel efficiency reforms. Add to this the enforcement question—from penalties to sustained compliance—and the framework looks more fragile than ambitious.

Ultimately, these norms hinge on implementation fidelity, especially at state and regional levels. Manufacturing innovation, consumer education, and policy enforcement must align in a way that breaks India's high-carbon vehicle trajectory. It is both too soon to praise and too early to dismiss. The risk is inertia, not ambition.
