Evidence about the environmental impacts of shared mobility is fragmented and scattered. In this article a systematic literature review is presented. The review focuses on assessments that use Life-Cycle Assessment to quantify the environmental impacts of car sharing, carpooling, bikesharing, and scooter/moped sharing. The results of these assessments were analyzed, as well as the factors that influence these impacts. Business-to-consumer car sharing, peer-to-peer car sharing, carpooling, bikesharing, and scooter/moped sharing can all cause gains and losses in terms of changing the environmental impacts of passenger transportation. The findings presented here refute unconditional claims that shared mobility delivers environmental benefits. Factors that influence changes in environmental impacts from passenger transportation from shared mobility include travel behaviour, the design of shared mobility modes, and how such schemes are implemented, as well as the local context. Local governments and shared mobility organisations can benefit from the analysis presented here by deepening their understanding of these factors and considering the life-cycle phase where the greatest impacts are caused.
关于共享出行对环境影响的证据零散且分散。本文进行了一项系统的文献综述。该综述聚焦于使用生命周期评估来量化汽车共享、拼车、共享单车以及电动滑板车/轻便摩托车共享对环境影响的评估。分析了这些评估结果以及影响这些影响的因素。企业对消费者的汽车共享、点对点汽车共享、拼车、共享单车以及电动滑板车/轻便摩托车共享在改变客运环境影响方面都可能带来收益和损失。此处呈现的研究结果驳斥了共享出行能带来环境效益的无条件说法。影响共享出行对客运环境影响变化的因素包括出行行为、共享出行模式的设计、此类方案的实施方式以及当地环境。地方政府和共享出行组织可以通过加深对这些因素的理解并考虑造成最大影响的生命周期阶段，从本文的分析中受益。
