This case study shows that the actual CO2 reductions of 18.6% achieved in the 2018 Camry exceed the 17.7% reductions predicted by EPA models. This confirms that the OMEGA and LPM models accurately predict both new technology benefits and synergies between technologies. It also suggests that other studies contradicting EPA model outcomes are inaccurate and underpredict future technology benefits.
Explores some of the compliance pathways available to heavy duty vehicle manufacturers. Specifically, this paper develops hypothetical technology packages for certain types of tractor trucks, vocational vehicles, and trailers using distinct technology strategies compares cost-effectiveness.
Investigated the impacts of updating three standards in Mexico to align with the international best practices employed in the rest of North America: gasoline and diesel sulfur standards, passenger vehicle emissions standards, and truck and bus emissions standards.
Advances in lightweighting (mass-reduction) designs and technology have surpassed projections made for the U.S. 2025 vehicle CAFE/GHG standard. Overall, weight reduction of ~15% should be feasible by 2025, at costs about one-third of 2012 estimates.
Surveys the existing literature on methodologies related to the certification of low ILUC biofuel projects through different measures. It also assesses the potential challenges, risks, and loopholes that could arise from the use of these methodologies.
Identifies auto markets with highest electric vehicle shares by region in the U.S., including smaller and medium size metropolitan areas. Analyzes electric vehicle promotion actions in place that are accelerating market development in the leading markets.
Compares the uptake of a range of vehicle technologies such as variable valve timing, gasoline direct injection, turbocharging, stop/start, as well as transmission and hybridization technologies in the U.S. and EU in recent years.
MEPC’s 70th session will consider two topics that may greatly reduce the amount of HFO used in the Arctic: a global marine fuel sulfur cap of 0.5% (currently it is 3.5%), and whether or not HFO use in the Arctic should be formally placed on the MEPC agenda. This paper provides key information needed to evaluate the potential risks HFO has to the Arctic environment.
