Life Cycle Assessment courses of study

Master’s Degree Course
Module Advanced Life Cycle Assessment and Ecodesign

The module «Advanced Life Cycle Assessment and Ecodesign» deals with methods used to quantify and reduce ecological footprints. In addition to the life cycle assessment basics, the module deals with Environmentally Extended Input-Output Analysis, Planetary Boundaries, Green Procurement, Supply Chain Management as well as Ecodesign and Eco-Innovation.
Furthermore, methodological concepts of regionalisation and the resulting LCA are covered. The module enables participants to transfer findings from applied science to industry and society through life cycle management and eco-innovation.
Module Life Cycle Sustainability Assessment

Environmental sustainability is the practice of using natural resources like water, soil, or air responsibly so they can support both present and future generations. Scientifically valid lifecyclebased information is crucial in order to implement sustainability strategies successfully. Life cycle assessment (LCA) is a helpful tool for aligning decisions with ecological criteria and reducing environmental impacts. This module covers LCA and related topics, including life cycle thinking, life cycle inventory modeling, and life cycle impact assessment from an environmental perspective. Other topics include the social and economic lifecycle perspective with social LCA and life cycle costing (LCC).
In groups, you will apply life cycle thinking and LCA methods to specific problems. The module enables you transfer insights from applied science to industry and society through life cycle thinking and life cycle management. You learn how to identify and develop effective sustainability measures that contribute to the global Sustainable Development Goals.
Master’s thesis topics
The following topics can be selected for master’s theses in the LCA Research Group.
Life cycle assessment of fish from aquaculture: where, how and which fish are produced?

The quantity of fish produced worldwide in aquaculture has almost doubled in the last 10 years, while the quantity of wild-caught fish has remained almost constant. But how sustainable is fish from aquaculture compared to wild caught fish?
From a sustainability point of view, it is crucial which fish species are produced, how the fish are produced (feed, production system, emissions and others), where they are produced and which imported products can be replaced by locally-produced fish.
In this master's thesis and in cooperation with the research groups Aquaculture Systems and Geography of Food, a comprehensive life cycle assessment of fish production from different aquaculture systems will be carried out and used for comparison with wild-caught fish. What is the ecological footprint, greenhouse gas emissions and water consumption of these products?
From traditional to postmodern: influence of lifestyle on individuals’ life cycle assessment

Traditional-bourgeois, achievement-oriented and modern, materialistic and consumption-oriented, creative and spontaneous - these are examples of qualities that characterise typical lifestyles. Classification of people into specific target groups is common in market and social research (for example sinus milieus or limbic segmentation). But how does lifestyle affect the environment? What optimisation measures are available for individual lifestyles?
Previous studies that have investigated the environmental impacts of private households generally start from the «average citizen». However, in order to reduce the environmental impacts of private consumption, messages specific to target groups are important. The aim of this master's thesis is to typify lifestyles and analyse the environmental impacts of individual lifestyles. Additionally, lifestyle-dependent optimisation measures can then be defined.
Environmental impact of next generation photovoltaic technologies

As part of the energy turnaround, the use of photovoltaics in Switzerland is expected to be expanded. Photovoltaics is an up-and-coming technology with significant potential. This potential is greatest for third-generation photovoltaic technologies, such as perovskite or organic photovoltaic cells, as well as various combinations of different cell technologies such as tandem cells.
But what are the environmental impacts of these new photovoltaic technologies and tandem cells?
In this master’s thesis, third generation photovoltaic technologies will be systematically evaluated and their environmental impact quantified. This will allow a comparison between different alternatives and the identification of options for optimisation. The specific technology to be investigated will be determined by the research group together with interested students.
Resource consumption of novel nutritional habits and food trends

In terms of consumption area of Swiss households, nutrition is responsible for the greatest consumption of resources.
In this master thesis, current changes in consumer behaviour and the extent to which food trends such as superfoods, insects, laboratory meat, low carb and more influence resource consumption are addressed.
Resource consumption of different food patterns will be quantified and ecological sustainability potentials identified.

Bachelor’s Degree Course
Minor in Sustainability Assessment

Life cycle assessments and labels are central instruments for designing sustainable processes and are used to communicate about and increase the visibility of sustainability.
This minor provides an excellent introduction to these instruments for aspiring sustainability experts. The following topics are covered:
- Identifying sustainability potentials in value chains
- Evaluation of labels with regard to sustainability
- Preparation and evaluation of life cycle assessments
Module Life Cycle Assessment

As a sustainability expert, you are often confronted with controversial questions about the environmental impact of decisions in your job. In this module, you will gain in-depth insight into the comprehensive assessment of environmental impacts over the entire life cycle of a product or service.
By applying life cycle thinking to a specific case study, you will learn to systematically analyse environmental impacts and promote sustainable, science-based decision-making in various sectors of the economy. In the end, you will be able to quantitatively assess the environmental sustainability of products and design innovative solutions for a sustainable future.
Module Systems and Models I

The world is complex, and we want to understand and improve it. To develop sustainable solutions for current problems, we must recognize systematic interconnections. You will learn fundamental system concepts and work with concrete examples that are relevant to your future professional fields. Models will help you understand complexity and identify influencing factors and impacts.
You will learn to analyze systems and present them clearly. An appropriate delimitation is an important factor in this process. Presenting systems fosters a shared understanding, which is crucial for successful collaboration in projects.
