The sharing economy has emerged as a potential way to reduce the environmental impact and costs of using products, whilst increasing their accessibility. However, there is a paucity of literature on its sustainability implications. To help fill this void we provide a first indicative assessment of the potential sustainability implications for the sharing of three product groups in Sweden, namely cars, small electrical tools and offices. A quantitative assessment of Greenhouse Gas (GHG) emissions, resource use and waste based on case studies, is used as a basis to develop scenarios of upscaling sharing at national level. This is combined with a qualitative scoring framework to assess the socio-economic impacts. Office sharing was found to have a significant potential to reduce GHG emissions by 164–243 KtCO₂e/yr. Car sharing has a larger potential but has a wide range of uncertainty with potential reductions of 0.5–3.7 MtCO₂e (if 80% of cars in Sweden were sharing cars), depending on how many owned cars are replaced by a shared vehicle. However, 80% ownership of battery electric vehicles offer a greater potential benefit with a saving of up to 8.2 MtCO₂e. In terms of the reduction in material use, there are potential savings of 232,000 t/yr and 24.4-34.4Mt/yr for cars and offices, respectively. However, the tool sharing case does not demonstrate such large potential for national reductions. The qualitative analysis on socio-economic implications showed largely positive results across the indicators. However, further research is needed to assess the impacts on jobs and the local economy for the shared product groups, and to more fully understand how shared offices effect health and well-being of users. Finally, to avoid potential rebound effects additional support is needed to promote electric cars to avoid fleets of fossil fuel cars with high emissions, a flexible stock of desks without large empty office spaces, and proximity of tool sharing to minimise transport.

共享经济已成为减少对环境的影响和降低产品使用成本，同时增加产品可及性的潜在途径。但是，关于其可持续性影响的文献很少。为了填补这一空白，我们对共享瑞典三个产品类别（汽车，小型电动工具和办公室）的潜在可持续性影响进行了首次指示性评估。根据案例研究对温室气体（GHG）排放，资源使用和废物进行定量评估，以此作为制定国家一级共享规模提升情景的基础。结合定性评分框架来评估社会经济影响。人们发现，办公室共享具有将温室气体排放减少164–243 KtCO ₂的巨大潜力。e / yr。共享汽车的潜力更大，但不确定性范围很广，潜在减少量为0.5–3.7 MtCO ₂ e（如果瑞典80％的汽车正在共享汽车），取决于共享车辆替换多少辆拥有的汽车。但是，电池电动车拥有80％的所有权可带来更大的潜在利益，最多可节省8.2 MtCO ₂e。就减少材料使用而言，汽车和办公室分别可节省232,000吨/年和24.4-34.4Mt /年。但是，工具共享案例并没有显示出如此大的削减国家潜力的可能性。对社会经济影响的定性分析显示，各项指标均取得了积极成果。但是，需要进一步研究以评估共享产品组对工作和当地经济的影响，并更全面地了解共享办公室如何影响用户的健康和福祉。最后，为了避免潜在的反弹影响，需要额外的支持来推广电动汽车，以避开高排放量的化石燃料汽车，灵活的办公桌，没有大的空办公室空间，以及接近的工具共享以最大程度地减少运输。
