Discusses the use of computer simulation to certify whole-vehicle efficiency of HDVs, and compares tools used to quantify HDV CO2 emissions in the US (GEM v2.0) and EU (VECTO v2.0.3 beta; not yet used in a regulatory context).
Evaluation, based on leading technology effectiveness, technology cost, and fuel price data, of payback periods for the efficiency technologies analyzed in a companion paper on tractor-trailer technology potential.
Assesses, through simulation modeling, the potential of various efficiency technologies to improve tractor-trailer efficiency in long-haul applications, 2020–2030.
Analysis of data, technologies, and regulatory design considerations related to establishing efficiency standards for commercial heavy-duty pickups and vans.
Evaluates eight vehicle replacement programs from around the world and identifies five best practices in the areas of program design and implementation, as well as fiscal incentives and policies, to serve as guidelines for policymakers.
Explores performance levels and adoption rates of trailer technologies that reduce fuel consumption in tractor-trailers and identifies challenges and opportunities going forward by capturing a broad cross-section of experts in the Canadian trucking industry.
Reviews and summarizes data on commercial vehicle sales and real-world fuel consumption for tractor-trailers in these key markets, which together account for more than 70% of HDV sales worldwide.
Describes the OBD deployment schedule and monitoring requirements for HDVs in Brazil, China, Europe, India, and the United States (EPA and California’s Air Resources Board).
Compares dynamics of the most important driving cycles and their impacts on fuel consumption and CO2 emissions to produce an updated set of conversion factors for translating distance-based CO2 emissions among the different driving cycles.
First place is a three-way tie between Alaska, Spirit, and Frontier, but overall the fuel efficiency of U.S. domestic airlines showed no improvement in 2013. The slowing efficiency gains since 2010 highlight the need for policies to reduce aviation carbon emissions.
