Govt proposes emission rule changes to boost ethanol blends, flex-fuel vehicles
The Indian government has proposed amendments to vehicle emission rules to support higher ethanol blends and alternative fuels, enabling the use of flex-fuel and pure biofuel vehicles across all vehicle categories. The draft changes to the Central Motor Vehicles Rules, 1989, introduce regulatory provisions for fuels like E85, E100, B100 biodiesel, and hydrogen-CNG blends, expanding beyond the current E10 and E20 standards. The proposals, open for a 30-day public consultation, aim to reduce emissions and align Indian regulations with global standards while allowing continued use of conventional lower-ethanol fuels.
