What This Article Covers

1.The third draft of CAFE-III norms retains the April compromise formula with a flatter weight-adjustment curve, reducing SUV advantage and easing targets for lighter vehicles.

2.Overall fleet emission targets are relaxed by ~21% compared to the original September 2025 proposal, with a target of 3.996 L/100km (94.76 gCO2/km) in 2027-28 tightening to 3.327 L/100km (78.90 gCO2/km) by 2031-32.

3.New Carbon Neutrality Factors (CNFs) allow specified CO2 reductions for ethanol, flex-fuel ethanol, CBG and other biofuels, and compliance is assessed over two blocks (3-year + 2-year) instead of annually.

The Big Picture
Prelims · HighMains · Medium

The government released the third draft of CAFE-III norms, retaining a compromise formula that flattens the weight-adjustment curve, reduces the compliance advantage for heavier SUVs, and introduces Carbon Neutrality Factors (CNFs) to recognize biofuels. Fleet targets are relaxed by ~21% from the original proposal, but still tighten progressively from 94.76 gCO2/km in 2027-28 to 78.90 gCO2/km by 2031-32.
