- Globally, wind power is growing fast and in Sweden alone more than 3000 turbines have been installed since the mid-1990s. Although the number of decommissioned turbines so far is few, the high installation rate suggests that a similarly high decommissioning rate can be expected at some point in the future. If the waste material from these turbines is not handled sustainably the whole concept of wind power as a clean energy alternative is challenged. This study presents a generally applicable method and quantification based on statistics of the waste amounts from wind turbines in Sweden. The expected annual mean growth is 12% until 2026, followed by a mean increase of 41% until 2034. By then, annual waste amounts are estimated to 240,000 tonnes steel and iron (16% of currently recycled materials), 2300 tonnes aluminium (4%), 3300 tonnes copper (5%), 340 tonnes electronics (<1%) and 28,000 tonnes blade materials (barely recycled today). Three studied scenarios suggest that a well-functioning market for re-use may postpone the effects of these waste amounts until improved recycling systems are in place.

Tidskriftsartikel (refereegranskat)abstract
- The way by which various sources of external information interact in their effects on judgment is rarely investigated. Here, we report two experiments that examine how two sources of external information—an anchor (a reference price) and an eco-label—influence judgments of an objective fact (product price) and a subjective preference (willingness-to-pay for the product). Participants’ price judgments were drawn in the direction of the anchor point, whereas the eco-label resulted in higher judgments of objective fact (Experiment 1) but did not influence subjective preference (Experiment 2). Interestingly, the eco-label seemed to strengthen the effect of the high anchor in judgments of objective fact. Further, participants with higher environmental concern answered a higher price on the subjective preference questions when they received a high anchor, as well as a lower price when they received a low anchor in comparison to the low environmental concern group. This study demonstrates that various external information sources can strengthen each other’s effects on consumer belief about products, while the effects are weaker for consumers’ preferences. The implications of the results for decision making are discussed.

Tradeoffs between self and environment in environmental judgment and decision making
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- One of the greatest challenges of today is to change our behavior to act more pro-environmentally to reduce global warming. We need to make sacrifices for the environment, e.g., use a means of transportation that take a longer time but causes less CO2 emission. The present thesis aims to study different factors (intrinsic, extrinsic motivational, and extrinsic motivational-neutral information) that influence us when making tradeoffs between self and environment. Paper I examined how an anchor (a reference price) and an ecolabel influence price judgments. It was found that both a judgment of an objective fact (product price) and a subjective preference (willingness to pay for the product) were affected by an anchor. An eco-label resulted in higher judgments of objective facts. People with higher environmental concern were more affected by an anchor when stating their willingness to pay than their low concern counterparts. In Paper II and Paper III, an interaction between a high anchor and a normative message that put the emissions into context was found when making a tradeoff between CO2 emissions and travel time for a flight (Paper II) or a car journey (Paper III). People with higher concern for the environment gave a longer travel time when they received a high anchor (Paper II and Paper III) or no anchor (Paper III). Paper IV investigated how a survey measuring environmental concern can be divided to different indices and how they predict answers in a tradeoff task. The result suggests that a two-factor structure divided into ecocentric and anthropocentric concern is a possible alternative and that people scoring higher on any of the environmental concern indices were willing to travel for a longer time. Taken together, the results show that normative messages, anchors, and concern for the environment are factors that can influence and interact when people make tradeoffs between self and environment in environmental judgment and decision making.

What Influences People’s Tradeoff Decisions Between CO2 Emissions and Travel Time? An Experiment With Anchors and Normative Messages
- 2021
-
Ingår i: Frontiers in Psychology. - : Frontiers Media S.A.. - 1664-1078. ; 12
-
Tidskriftsartikel (refereegranskat)abstract
- One of the today’s greatest challenges is to adjust our behavior so that we can avoid a major climate disaster. To do so, we must make sacrifices for the sake of the environment. The study reported here investigates how anchors (extrinsic motivational-free information) and normative messages (extrinsic motivational information) influence people’s tradeoffs between travel time and carbon dioxide (CO2) emissions in the context of car travel and whether any interactions with environmental concern (an intrinsic motivational factor) can be observed. In this study, people received either a CO2, health or no normative message together with either a high anchor, a low anchor, or no anchor. People that received both a high anchor and a CO2 emission normative message were willing to travel for a longer time than those that only received a high anchor. If a low anchor was presented, no differences in willingness to travel for a longer time were found between the three different conditions of normative message groups, i.e., CO2 normative message, health normative message, or no normative message. People with higher concern for the environment were found to be willing to travel for a longer time than those with lower concern for the environment. Further, this effect was strongest when a high anchor was presented. These results suggest that anchors and normative messages are among the many factors that can influence people’s tradeoffs between CO2 emission and travel time, and that various factors may have to be combined to increase their influence over pro-environmental behavior and decisions.

Towards benchmarking of urban air quality based on homogenous surface emission
- 2023
-
Ingår i: Results in Engineering (RINENG). - : Elsevier. - 2590-1230. ; 20
-
Tidskriftsartikel (refereegranskat)abstract
- Here, it is presented a possible methodology and experimental model for benchmarking of air quality in cities. The concept behind the methodology is that a city’s inherent structure affects the potential for contaminant removal due to the resistance it poses to inflow. The approach is based on homogenous emission across the street surface network, representing a worst-case situation. Different levels of complexity can be used for benchmarking, making it valuable for evaluating different layouts. Additionally, an urban ventilation index suitable for these kinds of experimental studies has been suggested.

Applying a Systems Perspective on the Notion of the Smart City
- 2020
-
Ingår i: Smart Cities. - : MDPI AG. - 2624-6511. ; 3:2
-
Tidskriftsartikel (refereegranskat)abstract
- This paper focuses on the need for a widened definition of the notion of technology within the smart city discourse, with a particular focus on the “built environment”. The first part of the paper describes how current tendencies in urban design and architecture are inclined to prioritize high tech-solutions at the expense of low-tech functionalities and omits that information and communication technology (ICT) contrasts the art of building cities as an adaptable and habitually smart technology in itself. It continues with an elaboration on the need for expanding the limits of system boundaries for a better understanding of the energy and material telecouplings that are linked to ICT solutions and account for some perils inherent in smart technologies, such as rebound effects and the difficulty of measuring the environmental impacts of ICT solutions on a city level. The second part of the paper highlights how low-tech technologies and nature-based solutions can make cities smarter, representing a new technology portfolio in national and international policies for safeguarding biodiversity and the delivery of a range of ecosystem services, promoting the necessary climate-change adaption that cities need to prioritize to confer resilience.

Enabling Relationships with Nature in Cities
- 2020
-
Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 12:11
-
Tidskriftsartikel (refereegranskat)abstract
- Limited exposure to direct nature experiences is a worrying sign of urbanization, particularly for children. Experiencing nature during childhood shapes aspects of a personal relationship with nature, crucial for sustainable decision-making processes in adulthood. Scholars often stress the need to 'reconnect' urban dwellers with nature; however, few elaborate on how this can be achieved. Here, we argue that nature reconnection requires urban ecosystems, with a capacity to enable environmental learning in the cognitive, affective and psychomotor domains, i.e., learning that occurs in the head, heart and hands of individuals. Drawing on environmental psychology, urban ecology, institutional analysis and urban planning, we present a theoretical framework for Human-Nature Connection (HNC), discuss the importance of nurturing HNC for children, elaborate on the role of property-rights and the importance of creating collective action arenas in cities for the promotion of urban resilience building. As values and environmental preconceptions underly environmental behavior, there are limits to achieving HNC in cities, as presumptive sentiments toward nature not always are positive. We end by discussing the role of new digital technologies in relation to HNC, and conclude by summarizing the major points brought forward herein, offering policy recommendations for HNC as a resilience strategy that can be adopted in cities throughout the world.

First-Line Managers’ Leadership Behavior Profiles and Use of Gardens in Residential Care Facilities: An Interview Study
- 2023
-
Ingår i: Journal of Aging and Environment. - : Taylor & Francis. - 2689-2618 .- 2689-2626. ; 37:1, s. 65-84
-
Tidskriftsartikel (refereegranskat)abstract
- This study explored first-line managers’ leadership behavior profiles regarding their goals for utilizing the garden at residential care facilities for older people. Semi-structured interviews were conducted with a convenience sample of first-line managers (n = 12) in Sweden. Data were analyzed using deductive content analysis theoretically guided by the Three-dimensional Leadership Model. The results showed that the main leadership behavior profiles were related to the dimensions structure, relation and change. The managers emphasized workplace regulations and goals. They allowed staff to make decisions and encouraged them to see problems and opportunities.
