Department of Energy and Environment, Chalmers University of Technology




The two divisions of Physical Resource Theory and Environmental Systems Analysis within the Department of Energy and Environment at Chalmers University of Technology carry out interdisciplinary research in several fields related to sustainable development. Central to this work are analysis and modeling of the flows of resources (energy, food and materials) in society, with the aim of finding sustainable ways to meet the needs of a growing population. This work includes the development and adaptation of methods for environmental assessment of technological solutions, including life cycle assessment (LCA), ecological risk assessment and sustainability indicators. The research also includes assessment of policy options, for example in changes to the structure of consumption and production of food.


Rickard Arvidsson is an Assistant Professor at the Division of Environmental Systems Analysis at Chalmers. He works mainly with environmental and sustainability assessments, such as LCA, social life cycle assessment (SLCA), environmental risk assessment (ERA), and material and substance flow analysis (MFA/SFA). His main objects of study have been nanomaterials, and his current research is mainly focused on environmental and sustainability aspects of the new material graphene.

Professor Christel Cederberg of the Division of Physical Resource Theory has long experience of agricultural and food systems, from her early work as a crop consultant and later on from her research on the environmental effects of agriculture. She has conducted several studies on greenhouse gas emissions from livestock production and worked in depth with methods and data for carbon footprinting of food products. At present, her research has a focus on methods for assessing impacts of land use. She has had several commissions as an expert on livestock production, environment and carbon accounting, including for the FAO and for the Swedish Board of Agriculture.

Martin Persson is an Associate Professor at the Division of Physical Resource Theory. His research focuses on the distant drivers of tropical deforestation and he has developed methods for estimating deforestation footprints for land-based products and for analyzing how trade links consumers across the world to forest destruction in the tropics. Martin has been a visiting scholar at the Tropical Agricultural Research and Higher Education Center (CATIE), Costa Rica and Stanford University, USA, and is an appreciated lecturer at both undergraduate and graduate level in the topics of energy, climate change and climate policy. Martin also regularly holds lectures for policy-makers, business leaders, environmental organizations and the general public on land use, sustainability and climate change.
