项目摘要

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.

在已发表的生命周期评估（LCA）研究中，重点主要集中在空气排放及其相关影响（例如气候变化、酸化、毒性）。除了累积的一次能源需求之外，综合非生物资源的需求通常被忽视，并且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，包括水和土壤在内的非生物和生物资源的供应风险和未来稀缺性也没有得到充分解决。该提案的目的是开发一种与生命周期评估兼容的方法，用于评估生物和非生物资源（包括水和土壤）的使用，适用于各种产品和服务。该评估方法将针对不同的替代移动方案（即生物燃料和新动力总成技术的使用）进行示范应用和测试。这项具有挑战性且复杂的应用测试旨在证明该方法的实际可行性和科学稳健性。与目前的技术水平相比，解决了两个主要差距：首先，通过添加补充指标拓宽了LCA方法涵盖的影响范围，这进一步提高了其对于真正全面的环境评估和技术比较的适用性和科学稳健性。各种利益相关者可以将开发的解决方案和由此产生的方法改进应用于不同的用例，例如产品替代品之间的选择、创新技术的评估或现有生产流程的改进。根据预期的方法改进，涵盖了其他环境影响，这些影响可直接适用于更全面的可持续性评估。其次，扩展的 LCA 方法将应用于未来的移动概念，以测试实际适用性并得出有关技术的更可靠的结论。通过比较移动选项，可以识别与相应技术解决方案相关的机会和风险，从而为可持续移动的战略决策提供决策支持。同时，验证如此复杂的测试用例的适用性旨在证明扩展的 LCA 评估会产生有意义且实际相关的结果。
