CAFE Phase III marks the next stage of India’s fleet-level fuel efficiency framework, aimed at further curbing energy consumption and CO₂ emissions from passenger vehicles.

As countries around the world tighten their grip on vehicle emissions and fuel efficiency, India is getting ready for its next big regulatory leap — CAFE-III, set to kick in by 2027. But how does India’s approach compare to what the EU, USA, China, and Japan are doing?

India aims to significantly tighten fleet-average CO₂ emission targets for passenger vehicle OEMs, with limits becoming about 16% stricter by FY2028 and nearly 30% stricter by FY2032 compared to FY2027 levels. CAFE III proposes to materially raise the bar on fleet-average emission thresholds, with stringent norms, especially in the latter years.

According to the ICRA’s latest report titled “CAFE Phase‑III Decoded: Tougher Emission Targets, Compliance Choices, the estimated fuel saving potential could be around ₹ 38,000 crore. To achieve this, OEMs need to balance technology upgrades, EV push and credit mechanisms to manage compliance. Progressive tightening of emission limits under CAFE III is expected to drive a steady reduction in fleet-average fuel consumption, translating into rising annual as well as cumulative fuel savings over the compliance period, the report noted.

The framework introduces stronger compliance mechanisms, including annual tightening of targets, enhanced penalties, fleet pooling, carbon credit trading, super credits for EVs/hybrids, and dual MIDC-WLTP testing, thereby increasing regulatory pressure while providing flexibility in compliance. OEMs are expected to adopt a mix of vehicle efficiency technologies, higher EV/hybrid penetration, and credit purchases to bridge compliance gaps, with ICE-heavy manufacturers facing the highest risk.
