We outline the different layers and highlight major tasks and dependencies with regard to energy consumption and energy efficiency. With this view, we can outwork challenges and questions a future system architect must answer to provide a more sustainable, green, resource friendly, and energy efficient application or system. Therefore, all system layers must be considered individually but also altogether for future IoT solutions. This requires, in particular, novel sustainability metrics in addition to current Quality of Service and Quality of Experience metrics to provide a high power, user satisfying, and sustainable network.

T1 - COVID-19 and lockdown schooling: how digital learning environments influence semantic structures and sustainability knowledge JF - Discover Sustainability N2 - Promoting sustainable lifestyles through Education for Sustainable Development (ESD) is part of the UN’s Agenda 2030. Earlier empirical studies proved direct interactions with and in natural environments to be effective ESD methods. Pandemic-related lockdowns rendered such courses nearly impossible, which raised concerns about achieving the Sustainable Development Goals (SDGs) in general. To evaluate what young learners know about the concept sustainability so far and how it can be taught effectively online, we designed an online learning module tackling sustainability issues and compared it with data from an on-site intervention module for Bavarian 5th graders (~ 10 years old). Cognitive learning as well as attitudinal preferences of 288 learners were monitored in a pretest–posttest design. The learning module comprised two sections: One about botany, plant characteristics, and plant families; the other about the advantages and disadvantages of traditional as well as sustainable farming methods. The customized cognitive test and semantic differentials for sustainability and environmental protection produced three major findings: (1) A digital learning environment successfully and significantly increased sustainability knowledge (2) Learners clearly distinguished the concepts Sustainability and Environmental Protection (3) There is no direct correlation between semantic differential scores and learning outcome.

Three political perspectives on the sustainability of the German healthcare system JF - International Journal of Environmental Research and Public Health N2 - This review article deals with the topic of sustainability in the German healthcare system and presents an overview of how the six articles of our research relate to one another. After introducing to the context of the research, its internal principles, and the methods applied, three perspectives are presented, each also discussed in terms of the respective literature in sustainability science and political science. The review concludes by presenting a circular model and by discussing the general limitations as well as the practical implications of our research.

This article explores the integrative approach of carsharing into the overall transport system from an individual sustainable mobility perspective. The authors argue that for Singapore, taxi services are the strongest competitor for the establishment of free-floating carsharing systems. Low taxi fares and a high distribution rate provide easy access for consumers and show great advantages in correspondence with the prevalent transport measures. Furthermore, the Singaporean government considers taxi services as part of public transport that helps bridging public transportation gaps in door-to-door travel. The article draws on literature review and expert interviews to evaluate the current market conditions and analyse the pros and cons of carsharing systems and taxi services as integrated part of the public transport system. The authors conclude by stating that from a sustainable perspective, the goal is to replace private car ownership. Provision of multi modal choices and therefore co-existence of different individual transport opportunities is indispensable.
