- Harnessing solar energy by using photovoltaic cells has the potential to become a major CO2-free energy source. Materials requirements for the solar cells based on four types of thin-film photovoltaics have been estimated and compared with global reserves, resources and annual refining. The use of solar cells based on Cd, Ga, Ge, In, Ru, Se and Te as a major energy-supply technology has severe resource constraints. Other systems such as a-Si without Ge and crystalline silicon do not involve such constraints. For some of these metals, there is the risk of enhanced, environmentally deleterious concentrations in the ecosphere due to leakage from manufacturing, use or waste handling.

Greenhouse gas emissions and subjective well-being: An analysis of Swedish households

Tidskriftsartikel (refereegranskat)abstract
- In the contemporary discussion on society's transformation towards long-termclimate targets, it is often implicitly assumed that behavioral changes, unlike technological changes, would lead to reductions in human wellbeing.However, this assumption has been questioned by researchers, who instead argue that people may live better lives by consuming less and reduce their environmental impact in the process. In this study we explore the relationship between greenhouse gas emissions and subjective well-being, using a sample of 1000 Swedish respondents.Our results show that there is no strong link between an individual's emissions and subjectivewellbeing. We also analyze the relationship between specific emission-intensive activities and subjective well-being and find thatnone of the activities examined correlates with subjective well-being. Finally, we explore a hypothesis put forward in the literature, suggesting that a poor work-life balance, long commuting distances, and materialistic values may decrease individuals' subjective well-being and increase greenhouse gas emissions. Our results indicate that materialistic values do correlate with lower levels of well-being and to some extent also with highergreenhouse gas emissions.

Reflections on evaluating Challenge Lab by applying a proposed scheme for Sustainability Transition Experiments
- 2016

Ingår i: IST 2016 Book of Conference Papers.

Konferensbidrag (refereegranskat)abstract
- The Challenge Lab (CLab) is a neutral arena for triple helix stakeholders and an educational platform for master students to addresses complex challenges and system lockins. By the end of its third year, the CLab will have hosted nearly 100 students, producing 23 master thesis projects and 13 course projects. We present an evaluative case using the scheme proposed by Luederitz et al. (2016) for sustainability transition experiments which includes four main questions and a set of indicators for each question. We end with some general reflections on the evaluation method.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Rationale: Adolescents today use social media applications extensively and research demonstrates that peers in social media settings can influence adolescents regarding their food intake. These newly emerged channels also offer unique possibilities to observe adolescents’ dietary communication. Objective: This study aimed to explore how adolescents communicate food images in a widely used social media image-sharing application, Instagram. Methods: To find adolescent Instagram users we searched for images appended with the hashtag #14år (Swedish for “14 years”). The hashtag had been applied to 3479 images as of March 2014. However, as users change their privacy settings, delete their accounts, or change their user names, 1358 images were not retrievable. Users sometimes also applied the hashtag to several images, and we excluded accounts that we judged did not belong to adolescents (based on written and visual profile information); 1001 unique Instagram users’ photo streams were thus eligible for analysis. Content analysis was used to identify food items and categorize these based on types of food and how the food items were presented. Results: Most of the adolescent users (85 %) shared images containing food items. A majority of the images (67.7%) depicted foods high in calories but low in nutrients. Almost half of these images were arranged as a still life with food brand names clearly exposed. Many of these images were influenced by major food marketing campaigns. Fruits and vegetables only occurred in 21.8% of all images. This food group was frequently portrayed zoomed in with focus solely on the food, with a hashtag or caption expressing palatability. These images were often presented in the style of a cook book. Conclusions: Food was presented in varied ways. Adolescents themselves produced images copying food advertisements. This has clear health promotion implications since it becomes more challenging to monitor and tackle exposure to marketing of unhealthy foods to young people in these popular online networks because images are part of a lifestyle that the young people want to promote. Shared images contain personal recommendations, which mean that they may have a more powerful effect than commercial food advertising. Acknowledgements: This study was supported by grants from Formas - The Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (grant number 259-2012-38). We would also like to affirm our respect for Instagram users and their publically shared images which made it possible for us to conduct this research.
