Petra Sieber
Doctoral candidate in Technology


I am a  doctoral candidate at the Department of Energy and Technology,
Swedish University of Agricultural Sciences (SLU). My research concerns the
development of LCA methodology for assessing the climate impact of land use and renewable energy systems, with particular focus on surface albedo change.


Master courses on Life Cycle Assessment, Bioenergy and Sustainable Food Systems.


My research aims to improve the understanding of how land use change affects the climate via surface albedo, and how this effect compares to other climate impacts in renewable energy systems. Besides greenhouse gas radiative forcing, changing reflectance is the only other mechanism through which humans directly impact the Earth's radiation balance. Nevertheless, albedo receives little attention in project evaluation and decision making.

Biomass is an important source of renewable energy. Bioenergy has the potential to substitute fossil fuels and thereby abate carbon dioxide emissions. However, expanding biomass production gives rise to new environmental impacts from land use and land conversion. As a scenario of growing bioenergy supply, my research looks into the introduction of short rotation coppice on fallow land in Sweden. 

I work with field measurements, satellite imaginary, GIS and computer modelling to determine impacts on climate. My work combines a life cycle approach with temporal dynamics in a bioenergy system. I am interested in experimenting with different metrics to better display the timing and spatial scope of climate relevant processes.


My PhD project is is part of STandUP for Energy, a collaboration initiative between Uppsala University (UU), The Royal Institute of Technology (KTH), The Swedish University of Agricultural Sciences (SLU) and Luleå University of Technology (LTU).
