CAFE-III norms in India: What the new fuel efficiency rules mean for carmakers and emissions | carboncredit.io

India has notified CAFE-III, the third phase of Corporate Average Fuel Economy norms for passenger vehicles. The rules apply from April 2027 to March 2032 and require about a 16 percent improvement in fleet fuel efficiency, with the benchmark tightening from 3.996 litres per 100 km to 3.3273 litres per 100 km. Lighter cars get softer targets while heavier vehicles must improve more. Carmakers can comply through multiple pathways: EV and hybrid super credits, flex-fuel recognition, renewable fuel carbon factors, credit trading, and a buy-out mechanism run by the Bureau of Energy Efficiency. The compliance blocks and carry-forward provisions are meant to give manufacturers flexibility, but critics like Amitabh Kant have called the rules backward looking. The outcome will depend on how aggressively automakers shift their mix toward electric and hybrid models rather than buying credits to delay change.

CAFE-III is mostly about fleet averages and credit trading, so the real test is enforcement. The buy-out price and credit accounting rules will decide whether this pushes actual CO2 cuts or just lets automakers pay to keep selling inefficient engines. Watch how the Bureau of Energy Efficiency sets the buy-out rate.

The 16 percent improvement over five years sounds solid, but a lot depends on how the super credits are weighted. If EV credits let automakers offset a large share of petrol cars, the fleet-level CO2 outcome may look better on paper than on the road. Need to see the derogation factors and how the compliance blocks are counted.

Useful thread for anyone tracking India's transport decarbonisation. The interesting detail is the expanded list of recognised technologies from 4 to 12, plus flex-fuel and renewable fuel carbon factors. That broadens the compliance toolkit, but it also makes the accounting more complex and harder to verify.

The CAFE-III numbers only apply to new passenger vehicles, so the existing fleet will keep burning petrol for years. Real emissions impact depends on how fast older cars are scrapped and whether EV sales keep growing. The norms set a direction, but they are not a shortcut to cleaner air.
