ABSTRACT
In this chapter, the value of using nanotechnology to improve platinum group metal (PGM) stability in automotive emission-control catalysts is evaluated. The study is parametric, in the sense that we hypothesize an improvement that could be possible with nanotechnology and estimate the resulting environmental savings. Large savings suggest that developing the new technology would be beneficial. We estimate savings both with the EIO-LCA model and with a commercial life cycle assessment tool based on detailed process models, providing an opportunity to compare results from these different approaches. Further detail appears in Lloyd et al. (2005).
