India's Draft CAFE III Rules Would Give Emission Credits for E20 and Biofuel Vehicles

India has proposed a new phase of its Corporate Average Fuel Economy (CAFE) standards, and the draft CAFE III norms are drawing attention for a key change: vehicles running on E20 petrol and biofuels would receive emission benefits under the framework. The move signals a policy shift that treats lower-carbon liquid fuels as part of the compliance equation, rather than focusing solely on electrification or pure fuel-efficiency gains.

CAFE regulations set fleet-wide average fuel consumption targets for automakers. Meeting them requires a mix of more efficient engines, electrified models, and — under the new draft — fuels that reduce the net carbon footprint of vehicles already on the road. E20 is a petrol blend containing 20 percent ethanol, while biofuels cover a broader family of renewable fuels derived from biological sources.

For the industry, the proposal matters because it could ease the compliance burden on manufacturers that still sell large volumes of internal-combustion vehicles. Instead of pushing purely toward battery-electric lineups, the rules would recognize the role of alternative fuels in cutting emissions.

The draft is still at a consultation stage, so details could change before it is finalized. Still, its direction suggests India is aiming to keep multiple technology pathways open as it works toward its long-term decarbonization goals — a stance that could influence investment decisions across the auto sector.
