Abstract: A sharing economy is an alternative system that enables pro-environmental behavior by improving efficiency through product-sharing. However, some motivations and requirements for doing laundry can increase the environmental burden, which suggests that the laundry machine (LM) sharing is not necessarily sustainable. This study clarifies consumer motivations for laundry usage and assesses the feasibility of environmentally sustainable laundry behavior through LM-sharing. Consumer surveys were conducted in Tokyo and Bangkok with different LM-ownership proportions. Single-person households were targeted, reflecting Tokyo’s demographic situation. A scenario analysis was conducted to evaluate the effect of routine laundry behavior changes on greenhouse gas (GHG) emissions. Three main results emerged. First, Tokyo respondents used a coin-operated laundry machine (CL) for convenience, which private washers cannot provide, while Bangkok respondents used it for basic laundry needs. Consequentially, the Tokyo respondents, who used CLs, were responsible for more than three times the GHG emissions of Bangkok respondents. Second, the group using both private LM and CL was the least GHG-efficient group, regardless of region. Third, laundry behavior can reduce GHG emissions if consumer requirements are decreased. The results show that there is environmental significance in adopting LM-sharing for sustainable consumption and production systems that reflect regional characteristics.
