Greenhouse Gas Emission Impacts of Carsharing in North America

摘要: This paper evaluates the greenhouse gas (GHG) emission impacts that result from individuals participating in carsharing organizations within North America. The authors con ducted an online survey with members of major and evaluated change annual household emissions (e.g., impact) respondents joined carsharing. results show a majority households joining are increasing their by gaining access to automobiles. However, individually, these increases small. In contrast, remaining decreasing shedding vehicles driving less. collective reductions outweigh increases, which implies reduces GHG as whole. reported form observed impact, strictly changes physically occur, full also considers would have happened but were avoided due mean impact is -0.58 t GHG/year per household, whereas -0.84 household. Both means statistically significant. We present sensitivity analysis evaluate robustness find overall hold across variety assumptions. average vehicle kilometers traveled (VKT) year was found decline 27%. conclude evaluation aggregate based on current knowledge industry membership population.
