  abstract     = {{Um die international und national beschlossenen Klimaziele zu erreichen, müssen die verkehrsbedingten Emissionen in der Bundesrepublik Deutschland drastisch reduziert werden. Hierzu bedarf es einer umfassenden Mobilitätswende, welche die Etablierung emissionsärmerer und effizienterer Mobilitätsformen umfasst. Ein Lösungsansatz können on-demand Dienste bieten, die den öffentlichen Personennahverkehr bedarfsgerecht gestalten und so dessen Akzeptanz steigern. Zahlreiche bisher eingeführte on-demand Dienste mussten jedoch nach Beendigung des Projekt- bzw. Förderzeitraums wieder eingestellt werden. Maßgebliche Herausforderungen waren die Integration der Dienste in die bestehenden ÖPNV- und Mobilitäts-Strukturen sowie teilweise damit einhergehende ökonomische Aspekte. In diesem Beitrag wird eine Methode vorgestellt, welche neben der Einführung neuartiger Mobilitätsdienste auch die Entwicklung eines nachhaltigen Mobilitäts-Ökosystems anstrebt. Der Fokus liegt dabei auf ländlich geprägten Regionen und ihren besonderen Herausforderungen im Bereich des öffentlichen Nahverkehrs. Die Methode beschreibt ein fünf-phasiges Handlungsschema, in welchem Potenziale bestehender Strukturen genutzt, Mobilitäts-Stakeholder eingebunden und verhärtete Mobilitätsverhalten allmählich positiv verändert werden. Anhand der Initiative Neue Mobilität Paderborn wird aufgezeigt, dass mithilfe der Methode erste Schritte hin zu einem Mobilitäts-Ökosystem absolviert werden können. Darüber hinaus werden Einführungsszenarien für die neuartige, sich noch in der Entwicklung befindliche Mobilitätslösung NeMo.bil in einer Beispielregion erarbeitet.}},

  abstract     = {{To reduce transport-related environmental impacts, innovative mobility system approaches such as on-demand services are being developed. These can include operating vehicles that differ regarding their characteristics and application profile from privately owned cars in motorized individual transport. Studies on life cycle assessment and life cycle engineering of vehicle lightweight structures are mainly limited to these privately owned cars and the impact category of climate change. In this paper, a method for life cycle assessment-based engineering of lightweight structures in vehicles for various mobility system applications, including on-demand mobility services, is developed. The method enables the holistic life cycle assessment of lightweight structures in different mobility system applications considering parameter changes at the upstream products, component, subsystem, vehicle and mobility system levels, as well as the integration of results into engineering activities. A case study is used to show that the vehicle and mobility system application of lightweight structures can significantly influence their environmental impacts and the selection of ecologically preferable product designs. The application in vehicles for on-demand mobility services can lead to an increase in absolute use stage energy demand and environmental impacts compared to applications in privately owned vehicles for motorized individual transport. However, normalized to the transport performance provided, the lifecycle environmental impacts of structural components in vehicles for on-demand mobility services can be lower than in vehicles for motorized individual transport. The paper contributes methodically and with quantitative results to improved decision making in life cycle engineering activities for lightweight structures in mobility system applications.}},

  abstract     = {{In order to follow the 1.5 degree path of the Paris Climate Agreement, drastic greenhouse gas reduction measures are needed in the transport sector. The potential of public transport and new mobility services to reduce transport-related greenhouse gas emissions cannot yet be fully exploited, especially in rural regions. This paper presents the concept of an innovative mobility system, called NeMo.bil, that intends to fill the gap between individual and public transport to create a demand-oriented and sustainable mobility offer. The concept is based on convoy formation of autonomously driving lightweight vehicles serving the first and last mile and a larger towing vehicle carrying enough power and energy to move the convoy over longer distances at higher speeds. This combination of two different vehicles, intelligently controlled by a digital ecosystem, aims to significantly increasing energy, resource and cost efficiency. Based on an analysis of previous approaches for innovative mobility solutions, the concept is derived from a technical and sociological perspective and its potential for reducing energy demand is calculated.}},

  abstract     = {{<jats:p>Lightweight design is a common approach to reduce energy demand in the use stage of vehicles. The production of lightweight materials is usually associated with an increase in energy demand, so the environmental impacts of lightweight structures need to be assessed holistically using a life cycle assessment. To estimate the life cycle environmental impacts of a product in its developmental stage, for example, by life cycle engineering, future changes in relevant influencing factors must be considered. Prospective life cycle assessment provides methods for integrating future scenarios into life cycle assessment studies. However, approaches for integrating prospective life cycle assessment into product development are limited. The objective of this work is to provide the methodological foundation for integrating future scenarios of relevant influencing factors in the development of lightweight structures. The applicability of the novel methodology is demonstrated by a case study of a structural component in a steel, aluminium, and hybrid design. The results show that appropriate decarbonisation measures can reduce the life cycle greenhouse gas emissions by up to 95 percent until 2050. We also found that shifts in the environmentally optimal design are possible in future scenarios. Therefore, the methodology and data provided contribute to improved decision-making in product development.</jats:p>}},

  abstract     = {{<jats:p>The development of automotive components with reduced greenhouse gas (GHG) emissions is needed to reduce overall vehicle emissions. Life Cycle Engineering (LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic information and improvement potentials regarding eco-efficient products. Key factors influencing LCAs of automotive components, such as material production, will change in the future. First approaches for integrating future scenarios for these key factors into LCE already exist, but they only consider a limited number of parameters and scenarios. This work aims to develop a method that can be practically applied in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive components, considering relevant parameters and consistent scenarios. Therefore, pLCA methods are further developed to investigate the influence of future scenarios on the GHG emissions of automotive components. The practical application is demonstrated for a vehicle component with different design options. This paper shows that different development paths of the foreground and background system can shift the ecological optimum of design alternatives. Therefore, future pathways of relevant parameters must be considered comprehensively to reduce GHG emissions of future vehicles. This work contributes to the methodological and practical integration of pLCA into automotive development processes and provides quantitative results.</jats:p>}},
