Evaluation of biotic and abiotic resource use in the mobility sector - development of LCA compatible impact indicators, methods and concepts

在已发表的生命周期评估(LCA)研究中，重点主要放在对空气的排放及其相关影响(如气候变化、酸化、毒性)。除了累积的初级能源需求外，非生物资源的综合需求通常被忽视，所应用的非生物消耗潜力指标显示出方法上的缺陷。即使在迄今为止最全面的研究中，非生物资源以及包括水和土壤在内的生物资源的供应风险和未来的稀缺性也没有得到充分的解决。这项建议的目的是为评估包括水和土壤在内的生物和非生物资源的使用制定一种符合生命周期评价的方法，适用于所有类型的产品和服务。这一评估方法将针对不同的替代机动性选择，即使用生物燃料和新的动力总成技术，进行示范应用和测试。这一具有挑战性和复杂性的应用测试旨在证明该方法的实际可行性和科学稳健性。与当前技术水平相比，解决了两个主要差距：第一，通过增加补充指标，拓宽了生命周期评价方法所涵盖的影响谱，进一步提高了其适用性和科学稳健性，以便真正全面地进行环境评估和技术比较。开发的解决方案和由此产生的方法改进可由各种利益攸关方应用于不同的用例，如在产品替代品之间的选择、创新技术的评估或现有生产工艺的改进。根据预期的方法改进，涵盖了更多的环境影响，这些影响直接适用于更全面的可持续性评估。其次，将扩展的LCA方法应用于未来的移动性概念，以测试其实际适用性，并得出关于这些技术的更稳健的结论。通过比较各种流动方案，可以确定与各自技术解决方案有关的机会和风险，为有关可持续流动的战略决策提供决策支持。同时，对这样一个复杂测试案例的适用性验证旨在证明，扩展的LCA评估产生了有意义的和实际相关的结果。

In published life cycle assessment (LCA) studies the focus is mainly on emissions to air and their associated impacts (e.g. climate change, acidification, toxicity). With the exception of the cumulated primary energy demand, the demand of a comprehensiveset of abiotic resources is usually neglected and the applied abiotic depletion potential indicators show methodological deficits. Even in the most comprehensive studies to date, supply risks and future scarcity of abiotic as well biotic resources including water and soil are not fully addressed. The aim of this proposal is to develop an LCA compatibleapproach for the assessment of the use of biotic and abiotic resources including water and soil which is applicable to all kinds of products and services. This assessment method will be exemplarily applied and tested for different alternative mobility options, i.e. the use of biofuels and new powertrain technologies. This challenging and complexapplication test is intended to demonstrate both practical feasibility and scientific robustness of the approach. Compared to the current state of the art, two main gaps are addressed: First, the impact spectrum covered by LCA methodology is broadened by adding complementary indicators which further improves its applicability and scientific robustness for a really comprehensive environmental assessment and comparison of technologies. The developed solutions and resulting methodological improvements can be applied by a variety of stakeholders for different use cases like the choice between product alternatives, the assessment of innovative technologies or the improvement of existing production processes. Based on the intended methodological improvements additional environmental impacts are covered which are directly applicable in the context of more comprehensive sustainability assessments. Second, the extended LCA approach will be applied to future mobility concepts in order to test the practical applicability and in order derive more robust conclusions on the technologies. The comparison of the mobility options allows the identification of opportunities and risks associated with the respective technological solution which serves as decision making support for the strategic decisions with regard to sustainable mobility. Concurrently, the verification of the applicability for such a complex test case is intended to demonstrate, that the extended LCA evaluation leads to meaningful and practically relevant results.
