Abstract

Sociotechnical system studies of the reduction of greenhouse gas emissions from energy and transport systems Linda Olsson, 2015 Cover design: Per Lagman/LiU-Tryck Printed in Sweden by LiU-Tryck, Linköping, Sweden, 2015 ISBN: 978-91-7519-082-2 ISSN: 0345-7524 AbstractIt is agreed that greenhouse gas (GHG) emissions from energy and transport systems must be reduced. Technical means exist to reduce GHG emissions from these sources. However, these emission-reduction measures are not implemented to a high enough degree. In this thesis, it is assumed that this is because the reduction of GHG emissions from energy and transport systems is a wicked problem. Unlike a tame problem, which has an unambiguous definition and a finite number of welldefined solutions, a wicked problem is difficult to define, and its solutions are often intertwined with the problem. The "wickedness" of a wicked problem lies in the extreme difficulty of solving the problem, rather than in the problem itself.In this thesis, the wicked problem of reducing GHG emissions from energy and transport systems is studied by applying a sociotechnical systems approach to the introduction of renewable vehicle fuels, the production and use of biogas, the introduction of electric vehicles, and the sustainability of district heating. In addition, this thesis discusses how energy issues are approached in different contexts, and what implications different actions can have on GHG emissions.The analysis shows that a sociotechnical approach to energy systems analysis can offer insights with regard to how system boundaries are handled within GHGemission assessments and energy and transport policy. By problematising the use of system boundaries in GHG-emission assessments, this thesis explains how attempts to reduce GHG emissions could add to the wicked problem of GHG-emission reductions from energy and transport systems. GHG-emission assessments can give very different results depending on system boundaries. While these results can be used in attempts to solve this wicked problem, they can also contribute to complicating it. As solutions to wicked problems are mainly found in policy, the use of system boundaries in policy is studied. Results show that narrow system boundaries in energy and transport policy can hamper sustainable development of energy and transport systems. The use of wider system boundaries could facilitate approaches to solve the wicked problem of reducing GHG emissions from energy and transport systems by making the consequences and effects of policy actions more clearly visible.i ii SammanfattningDet är välkänt att energi-och transportsystemens utsläpp av växthusgaser måste minska. Tekniska förutsättningar för att minska utsläppen av växthusgaser från användning av energi och transporter existerar. Ändå genomförs inte åtgärder för att minska utsläpp av växthusgaser i tillräcklig utsträckning. I föreliggande avhandling antas detta bero på att minskandet av utsläpp av växthusgaser från energi-och transportsystem är ett 'wicked problem'. ...

Simulation Modelling of a Shift to Service-Based Offerings : Resource efficiency and operational implications in the context of the circular economy

“…In widening the scope, sustainable business models include not only products and services but also aspects of the organisation and its eco-system (Bocken et al, 2019). Subsequently, for evaluating the resource efficiency of entire societal systems, the concept STS lends itself as a unit of analysis (Olsson, 2015;Kanda et al, 2016). For a large-scale transition like that to a CE, systems thinking helps in being able to link system elements across domains (Webster, 2013;Pieroni et al, 2019).…”

The Role of Electric Vehicles in Reducing Climate Impact: Swedish Public Debate 2010–2018

“…are used in a study is also important, to ensure that results may be correctly interpreted. In environmental assessments, greenhouse gas emissions have been shown to vary to a great extent, depending on the choice of system boundaries (Börjesson 2009;Ma et al 2012;Olsson 2015;Wetterlund, Pettersson and Magnusson 2010).…”

Sustainability of the Biowaste Utilization for Energy Production

“…The magnitude of the environmental impact of the biomass anaerobic digestion and CHP unit depends on numerous factors, such as fermentation conditions (mesophilic, thermophilic), kinds of substrates (cow manure, bioethanol residue, algae, food wastes), biogas yield, energy demand for the own process of digestion and sanitation, transportation, digestate storage and method of utilization and climate condition. The scientific results related to influence of the renewable energy production and transportation processes to global problem, especially greenhouse effect, sometimes differ a lot [31][32][33]. Nevertheless, there are some common features, which allow determining the main tendency of the abovementioned processes and products contribution towards sustained environment.…”
