Measuring progress in packaging waste prevention : trends and gaps in communicated indicators from national policy and the food retail sector
Full text linkEffective packaging waste prevention requires appropriate indicators to monitor progress and design measures. This paper addresses the lack of research and standardization of packaging waste prevention indicators at the national and company levels. A two-part methodology is employed. First, a framework for inventorying indicators is established; then, the framework is applied to national waste prevention programs of European Environment Agency member and cooperating countries, as well as to published reports and communications of the German food retail sector. The analysis reveals that 23 out of 30 countries and 17 out of 32 companies use and communicate packaging waste prevention indicators. However, there are gaps in indicators addressing qualitative prevention as well as regulatory and economic instruments at the national level. At the company level, recycled content and the reduction of packaging are specifically addressed. The term “reduction” may involve various approaches, including replacing materials such as plastic with alternatives or simply reducing usage. Specific monitoring of secondary and transport packaging is lacking in both sectors. In terms of plastics, indicators lack consistency and clarity, potentially facilitating greenwashing at the corporate level. Monitoring and reporting practices vary, and few indicators have specific targets and monitoring schemes. Recommendations for improvement include establishing a common understanding of waste prevention, adopting a holistic approach to monitoring various packaging materials, enhancing indicator measurability, and harmonizing indicators through categorization and inventory frameworks. These improvements are crucial for effectively monitoring and addressing packaging waste prevention at both the national and industry levels
Ein frommer Antikapitalist : das sozial-ökologische Erbe von Papst Franziskus - zwischen Tradition und Gesellschaftskritik
No full textPapst Franziskus war ein besonderer Papst. Aus dem Globalen Süden kommend, rückte er die Armen und Machtlosen, also die Hälfte der Weltbevölkerung, ins Zentrum seiner kirchlichen Verkündigung. Mit der Enzyklika Laudato si' setzte er Maßstäbe für eine sozialökologische Kirche und wurde zu einer moralischen Stimme der globalen Klimabewegung. Zugleich blieb er in Fragen der Familienmoral auf traditionelle Positionen festgelegt, hielt jedoch Distanz zu christdemokratischen Parteien, denen es an glaubwürdigen Leitlinien für Gerechtigkeit und Erdpolitik mangelte.
Dieses Buch beleuchtet das sozialökologische Erbe von Franziskus aus umweltsoziologischer Perspektive und richtet den Blick auf seinen Nachfolger Leo XIV. Wird er den Weg fortsetzen und sich als Anwalt der Mittellosen und der Natur erweisen? Oder lässt sein Pontifikat zu, dass ein kultureller Rechtsruck die Stimmen der Armen und die Sorge um die Erde übertönt? Unter all den Streitfragen, mit denen er konfrontiert ist, wird auch diese darüber bestimmen, wie die Geschichtsschreibung dereinst seine Amtsführung beurteilen wird
Toward agentic AI : user acceptance of a deeply personalized AI super assistant (AISA)
Full text linkRecent scholarship underscores the transformative potential of generative AI in shaping consumer decision-making, preferences, and overall brand satisfaction. Among these technologies, chatbots and AI voice assistants are increasingly deployed in marketing to influence consumer behavior. A critical question, however, is whether consumers are willing to accept a new generation of such technologies. In July 2025, OpenAI introduced the agent mode of ChatGPT, which represents a shift toward highly personalized, multimodal, and autonomous systems. This study defines these systems as AI super assistants (AISA). Informed by the broader literature on AI adoption and consumer behavior, an adapted AIDUA model with perceived risk is proposed. Survey data from the Philippines (N = 407) was analyzed using combined PLS-SEM and NCA methods. The results show that users appear increasingly confident in their ability to engage with new AI technologies, indicating that they do not feel overwhelmed but instead perceive AISA's new features as manageable. Hedonic motivation, novelty value, performance expectancy, and effort expectancy were identified as necessary conditions for user acceptance, while perceived risk is a necessary condition for objection. These findings offer new insights into user perception toward AISA, with implications for responsible AI design and deployment

No full textDesigning social behaviour change in households : sustainable mobility intervention and follow-up study
Full text linkLimiting global warming to 1.5 degrees requires consistent action by people to change their lifestyles in order to limit annual household-related carbon emissions to 2.5 tonnes per person by 2030. As the required mobility reduction measures have already been identified, the challenge remains in scaling up the changes into a mainstream practice. Our study explored whether the involvement of close social communities, especially households, in the change process could be effective in achieving the required measures. Through a Climate Puzzle game intervention and a six-month follow-up study with 12 households in Espoo, Finland, we investigated the role of close social communities in implementing the planned sustainable mobility behaviour change. The findings are presented through 12 household narratives. These narratives show that the adoption of new sustainable mobility behaviours is influenced by both (infra)structural and social relationship factors and that close social communities can hinder or facilitate the shift of everyday mobility behaviours towards being more sustainable in diverse ways. The findings suggest that design interventions should target larger social communities rather than just individuals in order to achieve the 2.5 tonne target. The study also indicates that socially tailored interventions and low-carbon solutions should be developed and targeted at city districts to help households create and maintain lifestyle changes
Rapid assessment of the Clean Industrial Deal : an initial assessment of the EU Commission's industrial policy work programme for 2025-2029
Full text linkAt the end of February 2025, the EU Commission published the Clean Industrial Deal (CID). The paper describes how the decarbonization of European industry, the strengthening of competitiveness and innovation and the improvement of security of supply can be achieved together. To this end, the CID outlines a series of planned legislative initiatives and thus sets the guidelines for European industrial policy in the coming years. In an initial assessment, 14 researchers from the Wuppertal Institute analyze what the CID means for European - and thus indirectly for German - industrial policy
