India’s CAFE-III Rules Set New Vehicle Efficiency Targets
CAFE-III is a new set of rules to help make passenger vehicles use less fuel.
It applies in India from April 2027 through March 2032.
The rules look at the average fuel use of all eligible vehicles a company sells, rather than judging every model separately.
A company’s target depends partly on the average weight of its vehicles.
The targets become tighter over the five years.
Companies can use different fuel-saving technologies to meet them.
Some electric, hybrid, and flex-fuel vehicles receive extra credit in the calculations.
Companies can also earn, trade, carry forward, or buy credits under the rules.
Vehicle results will be reported using two testing procedures.
CAFE-III sets fleet-level fuel-efficiency standards for passenger vehicles, building on rules first introduced in 2017.
The norms apply to eligible M1 passenger vehicles made or imported for sale in India from April 1, 2027, through March 31, 2032.
A manufacturer’s annual fuel-consumption target is linked to the weighted average unladen mass of its eligible vehicles.
The framework recognizes 12 fuel-conservation technologies, offers super credits for specified cleaner vehicle types, and includes a Carbon Neutrality Factor for certain lower-carbon fuels.
Companies can manage compliance in two- or three-year blocks using earned credits, credit trading, or a Bureau of Energy Efficiency buyout mechanism; reporting uses both MIDC and WLTP.
