ICCT Flags Fuel-Saving Steps Ahead Of EPA’s ‘Phase 3’ Truck GHG Rule

As EPA gears up to issue new greenhouse gas rules for medium- and heavy-duty trucks, a clean transportation group is touting significant fuel efficiency improvements achievable in internal combustion vehicles even as the group also encourages a “fast transition” to zero-emission vehicles (ZEVs). “There remains significant potential to improve the efficiency and GHG emissions performance of internal combustion engine vehicles (ICEVs) beyond 2027, and this potential should also be considered when setting the stringency of the [phase 3] standards,” the...
