CNG is a cost-effective fueling choice for heavy-duty commercial vehicles also. A study performed for the California Air Resurces Board (CARB) analyzes costs of 2010 heavy-duty diesel and natural gas technologies, using a life-cycle cost model. The financial model predicts that the break-even points for CNG for a refuse hauler, transit bus, and short haul heavy-duty truck are $22 barrel, $31 per barrel, and $28 per barrel of crude oil, respectively, in 2010 world oil prices. The detailed report developed by TIAX, LLC, is available to review online at the their website:
