Overview
- The proposal ties each automaker’s target to average fleet mass and tightens annually from roughly 3.726 to 3.014 litres/100 km between FY28 and FY32.
- Petrol cars under 4 metres, below 909 kg and 1,200 cc can deduct 3 g CO2/km from declared emissions, capped at 9 g/km per reporting period.
- Super-credits raise the impact of cleaner models in fleet averages: BEVs and range-extender EVs count as 3, plug-in hybrids and ethanol strong hybrids as 2.5, strong hybrids as 2, and flex-fuel ethanol cars as 1.5.
- A carbon neutrality factor discounts tailpipe CO2 for certain fuels and technologies, including an 8% cut for E20–E30 petrol, about 5% or more for CNG depending on biogas blending, and 22.3% for flex-fuel strong hybrids, while hydrogen incentives from the 2024 draft are removed.
- Compliance options include pooling of up to three manufacturers and an exemption for makers selling fewer than 1,000 units annually, with MoRTH and BEE enforcing penalties per g/km exceedance and WLTP/MIDC data submissions required ahead of WLTP adoption.
