Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system.
Assesses charging infrastructure deployment practices, challenges, and emerging best practices in major electric vehicle markets. Statistically analyzes the relationship between public charging and electric vehicle uptake at the metropolitan area level to better discern local infrastructure variation, practices, and circumstances.
Assesses zero-emission heavy-duty vehicle technologies to support decarbonization of the freight sector in the 2025–2030 timeframe. Synthesizes data from the research literature, demonstrations, and low-volume commercial trucks regarding their potential to deliver freight with zero tailpipe emissions. Analyzes the emerging technologies by their cost of ownership and life-cycle greenhouse gas emissions for China, Europe, and the United States.
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.
Introduces a novel methodology to monetize the benefit to consumers of electric vehicle incentives provided by U.S. states, and finds that more battery-electric vehicles are sold in states offering a greater total package of incentives.
Identifies six certification options, using Phase 1 and publicly expressed industry viewpoints as a guide, and evaluates them based on seven criteria developed to compare the certification procedures’ relative merits.
Assesses fuel consumption and fuel-efficiency technology adoption in China’s LCV market in 2010, focusing on differences among vehicle sub-categories and manufacturers, and compares fleet features and technologies in the U.S., EU, and China.
Documents the discrepancy between type-approval and real-world NOx emissions from new diesel passenger cars. On average, on-road NOx emissions from the vehicles tested for this analysis were about seven times higher than the limits set by the Euro 6 standard.
Builds on recent research on the integration of trailers into HDV fuel consumption and GHG emissions regulations to conclude that the U.S. Phase 2 rule presents an opportunity to capture substantial and highly cost-effective efficiency gains from technology improvements.
Comparative analysis of interim progress reports from the industry teams participating in the SuperTruck program, showing all to be on schedule in reaching the program’s technology R&D and vehicle-efficiency goals.
Details differences in the fiscal policies used to support electric vehicle sales across eleven major auto markets. Tax exemptions and subsidies are playing a key role in spurring electric vehicle markets, but in widely divergent ways.
