In order to achieve climate change mitigation goals, reducing greenhouse gas (GHG) emissions from Japan’s household sector is critical. Accomplishing a transition to low carbon and energy efficient consumer goods is particularly valuable as a policy tool for reducing emissions in the residential sector. This case study presents an analysis of the lifetime of personal vehicles in Japan, and considers the optimal scenario in terms of retention and disposal, specifically as it relates to GHG emissions. Using data from Japan, the case study shows the critical importance of including whole-of-life energy and carbon calculations when assessing the contributions that new technologies can make towards low carbon mobility transitions. While energy-efficiency gains are important, replacing technologies can overlook the energy and carbon embedded in the production phase. Without this perspective, policy designed to reduce GHG emissions may result in increased emissions and further exacerbate global climate change.
