text: 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.

text: 'New technologies and materials carry significant potential for sustainable
production and use of products. As an example, Additive Manufacturing technologies
and materials promise lightweight design and energy efficient use of parts. Exhausting
the full potential requires: a) consideration of uncertainties with respect to
future capabilities, and b) upgradeable design guidelines to cover advancements
consistently. The proposed approach merges concepts of Design-for-X with foresight
algorithms of Scenario-Technique to derive actionable knowledge. It is validated
by an application in the field of Additive Manufacturing, namely Metal Fused Deposition
Modelling. Engineers benefit from the intuitive access to heterogeneous types
of sustainability related information.'

text: 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.

text: 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.
