Faglig innhold

Bioenergy systems are an important component of policies aiming at mitigating climate change and enhance energy security. Life Cycle Assessment (LCA) is one of the most common methodologies used to quantify the environmental impacts of energy systems. Given the peculiar and variety of features that characterize biomass and bioenergy systems, it is extremely important to follow rigorous and informed procedures while undertaking LCA of bioenergy systems, especially regarding their global climate impact. The aim of this PhD course is to provide attendants with the most up-to-date and accurate practices to undertake thorough and comprehensive analyses of the physical effects of bioenergy on climate. The course will cover human-induced land perturbations caused by biomass harvest, impacts from temporary changes in atmospheric CO2 concentration caused by biogenic CO2 fluxes, changes in surface reflectivity (i.e., albedo), emissions through the value chains of various technological options for biofuels and other energy services. Attention is also given to other impact categories affected by bioenergy production, including impacts on biodiversity.


Attendants will learn how to assess the climate impact of biomass and bioenergy systems. They will acquire a flexible and dynamic approach to the topic, and will be able to gather data on CO2 fluxes both for direct emissions and from sites after harvest (reproducing CO2 sequestration fluxes and oxidations of dead organic materials and soil), collect albedo data from satellite observations, compare the different climate forcings into common units (radiative forcing), and elaborate normalized metrics like the Global Warming Potential (GWP). Participants will also become familiar with the modeling of specific Impulse Response Functions (IRF) to characterize different emission profiles, will be able to compute various climate metrics and understand they role in the interpretation of final results. Attendants will also learn approaches to estimate the impact of different land use changes on biodiversity, and will be able to identify and quantify key issues surrounding the effects of biomass and bioenergy systems on other impact categories.
