All about new CAFE norm
India has just locked in a tighter set of fuel-efficiency rules for cars and light commercial vehicles. The new standards, known as Corporate Average Fuel Economy phase three, will run from April 2027 through to March 2032. They set annual targets for how much fuel a manufacturer's entire passenger-vehicle fleet can burn and how much carbon dioxide it can emit. For UK businesses with operations in India, supply chains that touch the Indian automotive sector, or multinational vehicle fleets, these rules matter.
The norms work as fleet averages, not individual vehicle limits. Therefore, a manufacturer can still sell heavier, less efficient models as long as lighter or electric vehicles balance out the overall performance. This approach gives automakers flexibility in how they meet targets. However, the trajectory is clear: fuel consumption and emissions must fall year by year across the board.
India's Ministry of Power has confirmed the framework will take effect on 1 April 2027. The notification also raises the reference vehicle weight from 1,082 kilograms to 1,229 kilograms, reflecting the shift toward larger sport utility vehicles in the Indian market. This weight adjustment matters because the formula scales emissions targets according to vehicle mass. Lighter cars face tougher benchmarks per kilogram, while heavier vehicles get slightly more lenient treatment on a relative basis.
Fleet fuel-consumption targets drop by nearly 17 percent
Under the new rules, the fleet average for fuel consumption starts at 3.996 litres per 100 kilometres in the 2027 to 2028 financial year. By 2031 to 2032, that figure must fall to 3.3273 litres per 100 kilometres. That represents an improvement of roughly 16.7 percent over five years.
Meanwhile, the corresponding carbon-dioxide benchmark drops from 94.76 grams per kilometre to 78.90 grams per kilometre across the same period. Each year within the phase brings a step-down in the allowed average, so manufacturers cannot backload their compliance effort into the final year.
The rules introduce a credit and debit system. If a manufacturer beats its target in a given year, it earns credits that can be banked or traded. Conversely, missing the target generates debits that must be cleared in future years. This mechanism adds commercial incentive to outperform early rather than scrape past the minimum each year.
Battery electric vehicles and range-extended electric vehicles receive a volume multiplier of three. In other words, one electric vehicle counts as three vehicles when calculating the fleet average. This weighting makes it easier for manufacturers to pull down their overall emissions figure by introducing electric models, even if those models represent a small share of total sales.
Manufacturers selling fewer than 1,000 units a year in India are exempt from the Corporate Average Fuel Economy framework. For everyone else, compliance is mandatory.
Changes from earlier draft proposals
The final notification differs from earlier draft versions in several ways. Initially, the government proposed a separate concession for small cars weighing up to 909 kilograms. That carve-out has been removed in the final rules. Instead, the weight-based formula applies uniformly, with lighter vehicles facing stricter per-kilogram targets and heavier vehicles benefiting from a sliding scale.
The decision to raise the reference weight to 1,229 kilograms acknowledges market reality. Indian buyers have moved steadily toward larger vehicles in recent years, particularly SUVs. Setting the reference weight too low would have penalised the majority of new sales and risked making the targets unachievable for some manufacturers.
Industry groups have welcomed the final framework as more technology-neutral than the draft. The rules do not prescribe a single pathway to compliance. Manufacturers can pursue full electrification, hybrid powertrains, downsized turbocharged engines, weight reduction, aerodynamic improvements, or any combination that delivers the required fleet average. This flexibility is particularly important for companies operating across multiple price segments and vehicle categories.
How India's Corporate Average Fuel Economy framework has evolved
India introduced its first Corporate Average Fuel Economy standards in 2017. Those rules established the principle of fleet averaging and set initial benchmarks that were relatively easy for most manufacturers to meet. Phase two arrived in 2022, tightening the targets and introducing more granular reporting requirements. Phase three represents a further step-down, bringing India closer to the efficiency levels required in Europe and other developed markets.
The phased approach has given manufacturers time to adjust their product mix and invest in new powertrains. Nevertheless, the pace of tightening is accelerating. The gap between phase two and phase three is larger than the gap between phase one and phase two. Consequently, automakers that have deferred efficiency investments may find the next five years more challenging.
The Ministry of Power has emphasised that the framework aligns with India's broader climate commitments and energy security goals. Passenger vehicles account for a significant share of oil consumption in India, and reducing that demand lowers both import bills and carbon emissions. For the government, Corporate Average Fuel Economy is a tool to achieve both economic and environmental objectives without resorting to outright bans or punitive taxation.
Five things UK businesses should know
- Fleet fuel-consumption targets tighten from 3.996 litres per 100 kilometres in 2027 to 3.3273 litres per 100 kilometres in 2032, a reduction of approximately 16.7 percent.
- Carbon-dioxide emissions benchmarks fall from 94.76 grams per kilometre to 78.90 grams per kilometre over the same period, with annual step-downs throughout the phase.
- Battery electric and range-extended electric vehicles count as three vehicles in fleet calculations, creating a strong incentive for manufacturers to introduce electric models.
- The reference vehicle weight has been raised to 1,229 kilograms, reflecting the shift toward larger vehicles in the Indian market and adjusting the weight-based formula accordingly.
- A credit and debit system allows manufacturers to bank overperformance or carry forward shortfalls, adding flexibility but also creating financial consequences for persistent non-compliance.
Implications for UK manufacturers and supply chains
Several UK-based automotive manufacturers have production facilities or joint ventures in India. For these businesses, the new rules will require investment in more efficient engines, lightweighting technologies, or electric powertrains. Compliance costs will vary depending on current fleet composition. Companies with heavy SUV lineups face steeper challenges than those selling smaller, lighter vehicles.
Supply-chain effects will ripple beyond vehicle assembly. Component suppliers producing engine parts, transmissions, exhaust systems, and fuel-delivery systems will need to adapt to new specifications. Similarly, suppliers of batteries, electric motors, and power electronics will see increased demand as manufacturers pursue the three-times multiplier for electric vehicles. For UK firms exporting automotive components to India, understanding these shifts is essential for maintaining competitiveness.
Businesses that operate commercial or corporate fleets in India should also pay attention. As manufacturers reformulate their lineups to meet Corporate Average Fuel Economy targets, the mix of available vehicles will change. Smaller engines, hybrid options, and electric models will become more common. Fleet managers may find that total cost of ownership calculations shift in favour of electric or hybrid vehicles, particularly as fuel prices remain volatile.
For companies tendering for contracts with Indian public-sector buyers, sustainability credentials are increasingly important. Demonstrating compliance with local environmental standards, including vehicle emissions, can strengthen bids. Understanding how Corporate Average Fuel Economy interacts with procurement criteria gives UK businesses an edge when competing for Indian government or state-owned enterprise contracts.

We also support companies preparing for similar fleet emissions standards in the UK and EU, where comparable frameworks are already in place.
Technology pathways and compliance strategies
Manufacturers have several options for meeting the new targets. Full electrification offers the strongest compliance benefit because of the three-times volume multiplier, but it requires substantial upfront investment in battery supply, charging infrastructure, and consumer education. Hybrid powertrains provide a middle path, improving efficiency without the range anxiety or infrastructure constraints of pure electric vehicles.
Downsized turbocharged engines remain a popular choice for conventional vehicles. By replacing larger naturally aspirated engines with smaller forced-induction units, manufacturers can reduce fuel consumption while maintaining performance. This approach works well for brands that want to preserve a sporty or premium image without moving to full electrification.
Weight reduction is another lever. Advanced materials, aluminium body panels, and structural optimisation all contribute to lower fuel consumption. However, these changes often add cost, particularly in mass-market segments where price sensitivity is high. Manufacturers must balance the compliance benefit against the risk of pricing themselves out of the market.
Aerodynamic improvements, low-rolling-resistance tyres, and start-stop systems deliver incremental gains. None of these measures will single-handedly meet the targets, but in combination they can make a significant difference. For manufacturers with diverse portfolios, a mix of strategies across different vehicle lines is likely to be the most effective approach.

Wider context for global automotive regulation
India's move to tighten fuel-efficiency standards reflects a global trend. The European Union, United States, China, and Japan all operate similar frameworks, though the specific targets and methodologies differ. For multinational manufacturers, the challenge is managing compliance across multiple regions, each with its own timeline and technical requirements.
India's framework is broadly aligned with international best practice, using a weight-based formula and fleet-averaging approach similar to that used in Europe. However, the timelines and target levels are less aggressive than those in the EU, where manufacturers face even steeper cuts in carbon-dioxide emissions by 2030. This divergence means that a global platform designed primarily for European markets may need adjustment before it can be sold profitably in India, and vice versa.
For UK businesses, understanding these regional variations is crucial. A vehicle that meets Corporate Average Fuel Economy targets in India may not comply with UK or EU standards without further modification. Conversely, a highly efficient European model may be too expensive or unsuited to Indian driving conditions and infrastructure. Supply-chain planning, product development, and market strategy must all account for these differences.
Training and capacity-building also matter. Engineers, procurement managers, and sustainability teams need to understand the technical details of different regulatory frameworks and how they interact. Our SBS Academy offers training on international environmental standards, helping UK businesses build the internal expertise required to navigate complex multi-jurisdictional requirements.
