“…This value for national emissions is consistent with values for recent years given by Boden et al (2012Boden et al ( , 2012a For another comparison, this carbon savings would be equivalent to erasing the carbon footprint of over 5 million automobiles (average distance and fuel economy from Davis et al (2012), and assuming 2.43 kg-C (8.92 kg-CO 2 ) are emitted per gallon used, as per EPA (2012a). Table 4 shows the annual monetary savings corresponding to the carbon and energy savings above.…”

“…We aggregate vehicle vintages due to our coarser time series and lack of regional variation, but our data has the advantage of measuring the effect on vehicle prices over a much wider range of ages. 11 We employ the following specification for equilibrium price changes:…”

We estimate the sensitivity of scrap decisions to changes in used car values -the "scrap elasticity" -and show how it influences used car fleets under policies aimed at reducing gasoline use. Large scrap elasticities produce emissions leakage under efficiency standards as the longevity of used vehicles is increased, a process known as the Gruenspecht effect. To explore the magnitude of this leakage we assemble a novel dataset of U.S. used vehicle registrations and prices, which we relate through time via differential effects in gasoline cost: A gasoline price increase or decrease of $1 changes used vehicle prices and alters the number of fuel-efficient vs. fuel-inefficient vehicles scrapped by 18%. These relationships allow us to provide what we believe are the first estimates of the scrap elasticity itself, which we find to be about -0.7. When applied in a model of fuel economy standards, the central elasticities we estimate suggest that 12-17% of the expected fuel savings will leak away through the used vehicle market. This considerably reduces the cost-effectiveness of the standard, rivaling or exceeding the importance of the often-cited mileage "rebound" effect.

“…This increased diversity can be seen in fi gure 1, showing material decomposition in American automobiles over the latest 40 years [13,14]. Notably, the plastic and plastic composites as well as aluminum content have grown with time, while regular steel proposes a smaller portion of the materials with each year (from ~54 per cent to ~35 per cent) [13,14]. Looking at this shift for the industry, it seems like advances in material and manufacturing technology, along with increased demands on sustainability, enable new materials to be introduced and used increasingly in mass-produced vehicles.…”

Passenger vehicles are central to Western society, and contribute to a signifi cant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. One way to reduce mass is to introduce lightweight materials in the body of the vehicle. This research aims to explore the relationship between product and production system when introducing new materials.Besides a theoretical review and an industry-centered technological mapping, four case studies have been conducted during the course of this licentiate thesis. Two case studies were conducted with engineering design students working as development teams, one case study with the author as the developer and fi nally one case study in an industrial environment at a product owning company with in-house production.The goal of the case studies has been to increase the collective knowledge of how product development decisions aff ect production development decisions, and vice versa, when developing passenger vehicles in new materials.In the following analysis of case study outcomes, a number of factors important for introducing new materials are discussed. The relationship between product and production is investigated, both in terms of how the production system aff ects the product and how the product aff ects the production system. The outcome from this analysis is a mapping of important factors for automotive industry companies to understand and identify when looking at introducing new materials in existing production systems. Finally, a suggestion for future research eff orts is presented. ACKNOWLEDGEMENTS
