The ICT role in resource conservation and rebound effects

Abstract Information and Communication Technologies (ICT) sector takes a leading role in the new Economy experiencing an unprecedented growth rate. The author discusses environmental impacts focusing on resource consumption. In spite of increasing miniaturisation and resource efficiency of electronic products their consumption is growing threatening to give rise to rebound effects in material and energy consumption. The author addresses the problem and complexity of both direct and system-level effects from the ICT sector and discusses the role of government in coping with the potential environmental impacts

Foraging and mate-finding in the silver Y moth, Autographa gamma (Lepidoptera : Noctuidae) under the risk of predation

Animal foraging and reproductive behaviour is influenced by other simultaneous demands such as predator avoidance. The trade-offs between these demands may depend on sex or mating experience. This study demonstrates that the olfactory-mediated foraging and mate-seeking behaviours in the silver Y moths, Autographa gamma, are affected by auditory cues mimicking their bat predators. Both males and females changed their foraging behaviour under simulated predation risk. Fewer moths reached the odour source following sound stimulation and the time to find the odour source increased by up to 250%. However. there were no significant differences between male and female ability to reach the plant odour source or the duration of the flight towards the source when stimulated with ultrasound. Hence females are not more cautious than males when observed in the same behavioural context. Risk-taking in males was independent of whether they were flying toward a flower odour or sex pheromones having equal attractive value. This indicates that the trade-off between olfactory and acoustic cues is independent the type of odour. Mated females were not as strongly affected by sound as non-mated, indicating that flower odours have a higher adaptive value for mated females, suggesting that some processes following mating experience influence the trade-off between flower odours and simulated bat sounds

Product ban versus risk management by setting emission and technology requirements: The effect of different regulatory schemes taking the use of trichloroethylene in Sweden and Germany as an example

This report highlights the opportunities inherent in smart regulatory measures to effectively reduce risks related to hazardous substance emissions and exposure, and underscores the danger of simplistic and ineffective policy. The example of different regulatory approaches used in Germany and Sweden to regulate the use of trichloroethylene was taken as the basis for the study. During the 1990s, due to environmental, health and safety considerations, the use of trichloroethylene in Europe was a subject of broad concern. As a consequence, the use of trichloroethylene became regulated through multiple approaches, such as labelling, handling regulations and performance standards. Since that time the absolute emissions of trichloroethylene in Europe have been decreasing consistently in all member states. These results were achieved by various regulatory measures governing the use of trichloroethylene in industrial applications that have been introduced by individual Member States. However, given the implementation responsibility at Member State level not all member States have implemented the same set of regulatory measures. In Germany, for example, the use of trichloroethylene is regulated through strict technical standards for equipment and emissions that has required companies to replace existing old machines with the state-of-the-art equipment. In Sweden a general ban on trichloroethylene use was introduced in 1996, which however eventually evolved into an exemption permit system for companies that found no alternative to degreasing with trichloroethylene. --

Sustainable lifestyle choices in food and their rebound effects

The urgency of addressing the sustainability crisis requires a comprehensive approach encompassing both technological advancements and changes in human behavior. Food represents a crucial domain where everyday choices closely intertwine with environmental and social impacts. This study investigates the interplay between sustainable food strategies and rebound effects, which refer to the reduced effectiveness of measures due to economic and psychological responses following efficiency improvements. Drawing from the "EU 1.5-degree Lifestyles" project, we identified nine impactful strategies through a literature review and expert interviews. These strategies include minimising food waste, consuming tap water instead of bottled alternatives, reducing animal-based products, adopting vegan and vegetarian diets, and choosing organic, seasonal vegetables and fruits and food sharing. The findings from this study are valuable for policymakers seeking to develop effective and sustainable food policies while mitigating rebound effects. By understanding the rebound mechanisms associated with individual food strategies, policymakers can enhance the overall effectiveness of their measures and address the sustainability crisis more systematically

The importance of institutions and policy settings for car sharing – Evidence from the UK, Israel, Sweden and Finland

The rapid growth of cities requires effective management of transport demand and restructuring of transport systems to address the needs of growing urban populations in an environmentally, socially and economically sustainable way. In recent years, car sharing has emerged as an alternative to owning cars in cities, which has potential to bring environmental gains and address social considerations. There is a sizeable academic inquiry about the social and environmental benefits of car sharing and the barriers to its introduction and provision in different empirical contexts. However, most research on the determinants of its uptake and the ease of provision remains limited to investigating consumer demand and how to realise the benefits of car sharing. Drawing on cases from the UK, Israel, Sweden and Finland, this paper focuses on the institutional and policy settings to understand the systemic barriers for car sharing services in diverse urban contexts to expand knowledge on the challenges to and the challenges that emerge from car sharing schemes

Nordic Post-Graduate Sustainable Design and Engineering Research from a Supervisor Perspective

The multi- and interdisciplinary field of sustainable product innovation is rapidly expanding as an arena for scientific research. Universities in Nordic countries can be considered as an exponent of this type of research, with active research groups in, among others, Göteborg, Helsinki, Lund, Lyngby, Linköping and Trondheim. In the context of a Nordforsk funded project, seven second generation PhD supervisors from these universities, who have been active in this field for many years, discuss funding, publication, research traditions, education and supervision practices related to PhD research in this field. A number of recommendations to improve current practices are made, including the mapping currently existing differences in different academic institutions, studying the cross-over learning effects between academica and non-academic partners, and the development of ‘quality indicators’ of research in the SPI domain

Urban Sharing in Toronto

“Urban Sharing in Toronto” explores the landscape of the sharing economy in the city context. This research is a result of a Mobile Research Lab conducted by 8 researchers from Lund university in 2019. Specific focus is on three sectors: sharing of space, mobility and physical goods. For each sector, we discuss the drivers and barriers to the sharing economy, the associated sustainability impacts, the potential impacts on incumbent sectors, and the institutional context of sharing. Then, attention is turned to the role of the city council in engaging with the sharing economy and specific governance mechanisms employed by the city council are described. Since the sharing economy is not sustainable by default, urban sharing organisations, city governments and incumbents all have important roles to play in ensuring that the sharing economy positively impacts cities and their citizens. In the face of negative perceptions and possible impacts of the sharing economy, we may need to be more deliberate in thinking in terms of scaling the sharing economy to the size, needs, and capacities of cities. In this report we provide five recommendations to the City of Toronto and its citizens.Insights contained within this report may support the City of Toronto and other Sharing Cities, as well as urban sharing organisations and third-party actors in Toronto and beyond in their strategic work with the sharing economy for sustainability

Quantum Smoluchowski equation: Escape from a metastable state

We develop a quantum Smoluchowski equation in terms of a true probability distribution function to describe quantum Brownian motion in configuration space in large friction limit at arbitrary temperature and derive the rate of barrier crossing and tunneling within an unified scheme. The present treatment is independent of path integral formalism and is based on canonical quantization procedure.Comment: 10 pages, To appear in the Proceedings of Statphys - Kolkata I
