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.
Summarizes the case for shifting to a footprint-based efficiency standard in China, and analyzes how compliance burdens on auto manufacturers might change.
Summarizes impacts of new vehicle mass reduction data on CO2 benefit and cost curves for light-duty vehicles in Europe, 2020–2025, and the effect that regulatory structures which do not fully reward or penalize manufacturers for the influences of changes in vehicle mass might have on overall compliance costs of CO2 standards. Third in a series.
Assesses various potential index parameters for vehicle emissions performance standards and analyzes the effects of different target systems on individual manufacturers and vehicles.
Summarizes differences between size-based and mass-based vehicle standards and discusses their relative advantages and disadvantages.
