Purpose: This research aims to investigate the role of project-based-learning within graduate sustainability curricula through the lens of key competence development. Project-based learning has become a widely recommended pedagogy for sustainability education. It is hypothesized that through collaboration, student autonomy and real-world application, students develop key competencies for sustainability. This paper also aims to examine the connection between project-based learning and competence development on a program level from the student perspective. Design/methodology/approach: This two-year comparative case study follows the project-based-learning journeys of nine graduate sustainability students from three programs: the Master's of Sustainability at Arizona State University, the Master's of Sustainability Science at Leuphana University of Lüneburg and the Global Sustainability Science Master's, an ASU and Leuphana collaboration. Over four semesters, the students each took part in four competence-oriented self-assessments and interviews to map their perceived learning throughout their programs. Additional contextual information was gathered from program and course materials and descriptions, instructor interviews and "in vivo" observations. Findings: The defining aspects of project-based learning including collaboration, student autonomy and real-world connection do contribute to students' self-perceived competence development. Student-driven and program-driven project-based learning experiences equally foster this result, as long as the pedagogical challenges of balancing support and student independence associated with each are mitigated through instructor actions, program design or individual student coping skills. Originality/value: The results of this research can support higher education institutions in designing sustainability programs aimed at competence development through project-based learning. The focus on the curricular and program level combined with repeated overtime student-reported attribution to specific courses and activities bridges the gap between individual course case studies and theoretical recommendations for curriculum design. In addition to length and depth, this study also forefronts student experience of curricula as delivered.

Purpose: For professional sustainability work, graduates need to be able to work in teams and collaborate with stakeholders; in other words, they need to have developed interpersonal competence. There is growing evidence that project-based sustainability courses facilitate interpersonal competence development. However, research so far has focused on single case studies and on assessing learning outcomes. The purpose of this study is to deepen the understanding of how graduate students learn interpersonal competence in project-based sustainability courses. Design/methodology/approach: This study adopts a multi-case study approach triangulating observations, semi-structured interviews and focus groups supported by Photovoice method. A comparison of three project-based sustainability courses in graduate programs at universities in the USA, Germany, Switzerland and Spain is conducted to gain generalizable insights on how interpersonal competence can be developed through project-based sustainability courses. Findings: Receiving inputs, experiencing, reflecting and experimenting are four learning processes supportive of interpersonal competence development. Interpersonal attitudes seem to be mostly learned through a combination of experiencing and reflecting, followed by experimenting; not surprisingly, interpersonal knowledge is mostly developed through a combination of receiving inputs, experiencing and (collective) reflection; and interpersonal skills seem to be mostly learned through a combination of receiving inputs and experimenting, or, more directly, experiencing and experimenting. Practical implications: These findings support the unique learning opportunities offered through project-based sustainability courses and can help instructors to better facilitate students' development of interpersonal competence. Originality/value: The value of this study is three-fold--(i) it provides a comprehensive picture of interpersonal competence, including attitudes, knowledge, and skills; (ii) it spells out specific teaching and learning processes; and (iii) it links these to specific interpersonal competence facets and components.

Creating connections between consumers and producers (relational proximity) seems a promising approach to foster sustainable consumption behaviour in international food supply. In this intervention study, we tested three experiential marketing interventions to connect consumers to producers of an international community-supported agriculture (CSA) partnership for coffee (Teikei Coffee). Consumers (N = 136), recruited at a fair for sustainable products and lifestyles in Germany, (a) watched a promotional video about the coffee CSA, (b) attended a presentation of the coffee CSA, or (c) participated in a mindful tasting experience of the CSA coffee. Findings indicate that experiential marketing tools, to varying degrees, indeed create connections from consumers to producers, thereby fostering sustainable consumption behaviour. The findings can inform international food supply marketing efforts aimed at stimulating sustainable consumption. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to present an experience-based learning framework that provides a bottom-up, student-centered entrance point for the development of systems thinking, normative and collaborative competencies in sustainability. Design/methodology/approach: The framework combines mental mapping with exploratory walking. It interweaves mapping and walking activities with methodological and theoretical inputs as well as with reflections and discussions. The framework aligns experiential activities, i.e. mental mapping and walking, with learning objectives, i.e. novice-level sustainability competencies. The authors applied the framework for student activities in Phoenix/Tempe and Hamburg/Lüneburg as part of The Global Classroom, a project between Arizona State University in the USA and Leuphana University of Lüneburg in Germany. Findings: The application of the experience-based learning framework demonstrates how students started developing systems thinking (e.g. understanding urban systems as functional entities and across different domains), normative (e.g. using different sustainability principles) and collaborative (e.g. learning across disciplinary, social and cultural differences) competencies in sustainability. Originality/value: The experience-based learning framework contributes to the development of curricular activities for the initial development of sustainability competencies in introductory-level courses. It enables students from different disciplinary, social and cultural backgrounds, e.g. in international education, to collaboratively start developing such competencies. The framework can be adapted to different educational contexts.

To advance holistic corporate sustainability in small and medium‐sized enterprises (SMEs) requires employees to fully engage in sustainability efforts, which, in return, means to develop employees' action competence for sustainability. Little empirical evidence, however, exists on how to do this considering well‐known constraints SMEs face (time, expertise, resources). We present a transdisciplinary project that developed, delivered, and evaluated a sustainability training for the workforce of the Bohlsener Mühle, an SME that has pioneered corporate sustainability in Germany. The training was piloted for the business' apprentices and combined different learning modes to build participants' sustainable action competence. The pre‐post evaluation, supported by observations and qualitative interviews, revealed that employees' action competence for sustainability can be fostered through such trainings and is most effective if organizational factors that enable a corporate culture of sustainability are aligned. We conclude that a human‐centered and action‐oriented approach to training is needed to unleash the full potential of the workforce to advance corporate sustainability. [ABSTRACT FROM AUTHOR]

Engineered nanomaterials pose many new questions on risk assessment that are notyet completely answered. Thus, voluntary industrial risk assessment initiatives can be considered vital to the environmental health and safety issues associated with engineered nanomaterials. We present an overview of the general properties of nanomaterial products in the market, and how industry, in general, approaches issues of nanomaterial risk and safety based on a written survey of 40 companies working with nanomaterials in Germany and Switzerland. It was found that the nanomaterials in this sample exhibited such a diversity of properties that a categorization according to risk and material issues could not be made. Twenty-six companies (65%) indicated that they did not perform any risk assessment of their nanomaterials and 13 companies (32.5%) performed risk assessments sometimes or always. Fate of nanomaterials in the use and disposal stage received little attention by industry and the majority of companies did notforesee unintentional release of nanomaterials throughout the life cycle. The development of risk and safety decision frameworks in industry seems therefore necessary to ensure that the potential risks of engineered nanomaterials are taken into consideration.
