Based on the ICCT Policy Update, October 2024
Timing
- Jan 1, 2026, for new type-approvals
- Feb 1, 2028, for all new vehicles
- CAFC phases in from 2026 to 2030
Changes from Stage 3 to Stage 4
- Test cycle changes from NEDC à WLTC
- Now includes NEVs and vehicles powered by gas/alcohol
- Compliance flexibilities
- Off-cycle credits
- NEV multipliers (phased out after 2030): 1.4 for BEV, PHEV, FCEV, and 1.2 for “energy-saving vehicle”
- Vehicle classes updated :
- Weight-based linear regression for determining fuel consumption limits instead of the prior weight-class basis – This will potentially prevent the loophole of lenient requirements by slightly increasing vehicle weight
- Reference weight switched from curb mass to test mass (Test mass = Ref. mass + Optional equipment + representative vehicle load)
