Kaplan, O., M. isik, T. Hottle, AND R. Dodder. A framework to analyze emissions implications of manufacturing shifts in the industrial sector: an illustrative case study for vehicle mass reduction. Presented at 36th USAEE/IAEE North American Conference, Washington, DC, September 23 - 26, 2018.
Impact/Purpose:
As emissions reductions are desired in end-use sectors –commercial/residential technologies and light- and heavy-duty vehicles – the corresponding changes in fuel use and technologies can lead to shifts in the upstream production processes. These “upstream” emissions can be associated with changes in fuel production, transport and distribution, and/or changes in the manufacturing of technologies. For example, automobile manufacturers are using VMR (also called “lightweighting”) of light duty vehicles as one of many strategies to improve fuel economy. As manufacturers shift toward materials like higher strength steel, aluminum alloys, magnesium alloys and composite materials such as carbon fiber reinforced plastics, shifts in the relative demand for these materials as well as changes in their production processes, efficiency, and location can occur. These changes will affect the emissions associated with these upstream sectors and have implications on the material supply chains. This paper explores the extent of the impact of uncertainties in upstream process emissions in the U.S. energy sector through future scenario planning methodology with different trajectories of energy infrastructure development and system operations, and varying social paradigms.
