Modifying the traditional production system and the culture of consumption is necessary to achieve a sustainable society. The product-service system (PSS) business model allows companies to progressively add services to physical products, thus promoting more pro-sustainable business outcomes. The purpose of this work is to verify how a PSS model can contribute to sustainability by analyzing two electric car-sharing projects using a set of five factors. As a methodological strategy, a Systematic Literature Review and a case study of the two projects (VAMO and EMOTIVE) were performed. Findings show benefits generated by both projects as to environmental aspects, mainly related to gases emission. It was also possible to observe social benefits due to income development and environmental awareness. This paper thus contributes to the discussion of the potential of the PSS models and how they can leverage business models toward a more sustainable society. Although the results are applicable only in this case, this article can motivate new projects and contribute to enriching the debate about sustainable solutions, as the literature in this field still provides few case studies showing these types of applications. 相似文献

A wind tunnel study was performed to determine the dispersion characteristics of vehicle exhaust gases within the urban canopy layer. The results were compared with those from a field monitoring station located in a street canyon with heavy traffic load. The agreement found was fair. In the second part of the paper it is shown how wind tunnel data can be utilized to supplement and thereby enhance the value of field data for model validation purposes. Uncertainty ranges were quantified which are inherent to mean concentration values measured in urban streets. 相似文献

High taxes on new cars in Israel provide an incentive for car owners to defer the purchase of new vehicles. The result is a vehicle fleet of older, more polluting vehicles, with air pollution costs estimated at up to $530 million annually. The purpose of this paper is to conduct a cost benefit analysis (CBA) of an accelerated vehicle-retirement (AVR) programme. The analysis considers the private car fleet as well as trucks and buses. The study develops an economic model to identify the optimal payment level that will maximise the net benefit of the programme, and then apply the model to three different vehicle categories. It finds that an AVR programme for private cars may indeed yield significant net benefits, while a similar programme for trucks and buses fails to meet the cost-benefit test. For private cars, the study finds that even according to a conservative estimate, the programme will result in the voluntary retirement of approximately 98,000 private cars, with a present value net benefit of more than $50 million. This is equal to a 17% reduction in total annual private car air pollution costs for the five-year time span of the proposed programme. 相似文献

我国(讨论稿)和欧洲关于行人保护法规的异同点 总被引:1,自引:0,他引:1
通过对欧洲和我国讨论稿关于行人保护法规的分析比较研究,在定义方面有着相同和不同;在下腿型冲击器对保险杠的试验、上腿型冲击器对保险杠的试验、儿童头型冲击器对发动机罩的试验、成人头型冲击器对发动机罩的试验等实验中,使用的实验仪器设备、实验手段和方法、实验程序、评价指标存在着相同和不同之处。与欧洲法规相比,我国讨论稿的一些评价指标值有待进一步完善,试验手段和方法需要进一步改进,通过比较分析来不断修订我国行人保护法规讨论稿,以利于我国未来正式颁布行人保护法规。 相似文献
