The Ministry of Power’s latest CAFE III notification is a hard‑line move: reference‑weight fleets must cut CO2 emissions from about 94.8g/km in FY28 to roughly 78.9g/km by FY32, with a yearly tightening schedule that will keep manufacturers on their toes.
The move isn’t just a number; it’s a new game plan for buyers. Stricter limits mean every new car must be cleaner, and manufacturers can trade or buy credits at ₹2,500–₹4,500 per g CO2/km, turning emissions into a marketable commodity.
Battery‑powered and range‑extended EVs get a super‑credit multiplier of 3.0, so a 200g/km emission profile could earn 600g of credit. For a buyer, that translates into potential cost savings or lower taxes down the road, especially as EVs already enjoy lower running costs.
Plug‑in hybrids and strong hybrids aren’t left behind either. PHEVs get a 2.5x multiplier, strong hybrids 1.6x, while flex‑fuel vehicles earn 1.1x. CNG, ethanol and bio‑fuel blends can claim up to 9g/km for efficiency techs, giving a clear incentive to look at alternative‑fuel models.
The ripple effect reaches Tier‑1 suppliers. Spark Minda’s CTO says the norms force suppliers to build electronics, lightweighting and power‑management solutions that span every powertrain, which could mean more local parts and lower prices for end‑users.
For the average buyer, the practical takeaway is a few things to watch: compliance starts April 1, 2027, WLTP reporting kicks in the same month, and credit trading will become a new layer of cost calculation. Models that score high on the super‑credit scale will likely see a price edge, while traditional ICE cars will feel the pinch.
Keep an eye on the market as the credit‑trading platform launches. The first blocks (FY28–30) will see the most aggressive price swings, and by FY31–32, the tightening will be even sharper. Buyers who stay ahead of the curve can leverage the new norms to pick greener, cheaper cars sooner.
