  text: <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>

  text: <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>
