3As cities strive for sustainable development, the concept of urban circularity is gaining increasing recognition as a framework for systemic transformation. Yet, tools used to assess circularity, such as questionnaires, are often limited to traditional measurement functions. This paper argues that adopting new methods for developing questionnaires can serve as both a mechanism for creating a circularity measurement tool and for initiating conversations with stakeholders. It details a co-creation process involving international stakeholders (architects, urban planners, local government representatives, and social scientists) in the development of a circularity questionnaire and argues that these should be context-driven, methodologically sound, and, more importantly, socially accountable tools that include all stakeholders. This paper emphasizes ensuring effective measurements of urban circularity through the participation of all perspectives, improving the development process and the quality of surveys, and increasing stakeholder participation and dialog to effect change and increase insights into circularity practices.

The rapid urbanisation of our societies calls for an urban renewal movement, including developing new areas to accommodate housing facilities and services and regenerating existing urban areas. Yet, urban renewal projects pose trade-offs impacting both environmental and socio-economic aspects. The renovation and new construction of buildings can escalate the use of energy and material resources as well as increasing greenhouse gas emissions. The European Union plays a leading role in promoting the transition towards sustainable and inclusive cities, whereas other regions such as North America, Australia and Asia follow suit via Circular Economy Action Plans or Frameworks, highlighting the need to enhance resource efficiency in buildings through the use of durable and circular materials. Current research on resource efficiency in buildings follows the Circular Economy concept, which aims to reduce the use of raw materials and the waste of existing materials while retaining their value for as long as possible. However, the role of the circular economy in sustainable transition and the adoption of its principles in urban contexts remain unclear while its practical implementation still faces significant challenges, including the lack of analytical instruments and assessment methods as well as co-creative approaches. This ‘Ten Questions contribution’ provides an overview of the pressing issues concerning circularity in the built environment, the state-of-the-art and best practices, challenges and benefits, policies and regulations, as well as numerous strategies applied on the building and neighbourhood level, assessment methodologies and future trends.

Organizations are currently facing substantial challenges regarding becoming circular by 2050 – also referred to as Circular Economy (CE). Subsequently, increasing complexity on all organizational levels creates uncertainty about respective organizational and technological capabilities and adequate strategies to develop these capabilities. Organizations are struggling in picking up the CE ambitions and answering the what’s in it for me question. Scholars are developing models and frameworks to enable organizations to measure CE performance. Over 125 assessment methods are available for micro level assessment – measuring up to 365 different metrics. Moreover, extant literature is available presenting barriers and opportunities for CE transformation focusing on industry, sector, region, etc. And, although a more holistic perspective is required to become circular mature, this is currently lacking. In this paper we present a multi-methodology view on approaches and how they are used (or not). Our main goal is to extend the existing body of knowledge with an eye on applicability and research directions to untie the Gordian knot of measuring circularity.

The urgency for developing a circular economy is growing, and more and more companies and organisations are concerned with the importance of adapting their business to fit a changing economy. However, many analyses on the circular economy are still rather abstract and there is a lack of understanding about what circularity would mean for specific industries. This insufficient insight especially seems to be apparent in the building and construction sector. Besides, the building and construction sector is responsible for a major part of energy use and emissions. To tackle the issue of insufficient insight into the business consequences of circular developments, further research is necessary. Therefore, we propose to collaborate on a research project that aims to provide a more detailed level of analysis. The goal is to identify drivers and barriers to make better use of materials in the building and construction sector. This further research would benefit from an international collaboration between universities of applied sciences and industry from different European countries. An additional benefit of the applied orientation would be the relevance for professional education programmes.

Anthropogenic climate change demands innovative educational approaches that effectively bridge sustainability concepts with practical learning. Particularly this applies to the broad context of sustainable energy education. The CIRCLE project (Creative Impulses for Recycling, Crafting and Learning) conducted by the Sustainable Technologies Laboratory at Bochum University of Applied Sciences offers a novel, problem-based learning environment which is initially designed to integrate analytical and practical applications of circular design principles into higher education sustainability courses. This paper illustrates how CIRCLE can furthermore successfully contribute to sustainable energy education. Referring to the example of a proton exchange membrane fuel cell it is shown in detail to what extent participating students not only assess and enhance product circularity but dealing with energy-related products simultaneously acquire theoretical knowledge of key facts, central concepts and relevant energy-related technologies as well as practical competencies. Future work will empirically assess CIRCLE’s educational outcomes and explore scalable curriculum integration, contributing to innovation in sustainability teaching and learning."

This study evaluates the effectiveness of the European Union's Corporate Sustainability Reporting Directive (CSRD) in quantitatively measuring the transition of companies to a circular economy. First, using the most recent literature review on circularity metrics, a complete overview of the currently available circularity metrics is developed. Subsequently, it is determined which circularity metrics can be generated with the available quantitative datapoints of CSRD. The metrics that can be generated were analyzed on their ability to cover all circular strategies, to represent different Product-as-a-Service systems and to acknowledge the key role of Critical Raw Materials in a circular economy. The study finds that, with data disclosed under CSRD, metrics can be generated to cover all circular strategies. However, gaps remain in representing pay-per-use and pay-perperformance systems and the use of Critical Raw Materials. Recommendations are to include ‘Product utilization’ and ‘Mass of Critical Raw Materials used’ in the data disclosed under CSRD and to have an independent institution report data to enable benchmarking of performances. Finally, this study concludes with an overview of the metrics which enable to measure circular transitions using data disclosed by CSRD

What are the opportunities and complications of a match between city challenges and game designers? How can policy officers or ‘problem owners’ cooperate with game designers to put a specific issue, problem or contribution to a public good ‘on the map’, and in turn how can game designers best pick up these kind of requests? These were the questions on the agenda for the Games for Cities Circularity Talk Show held on October the 11th 2016 at Pakhuis de Zwijger in Amsterdam

This paper explores the relationship between Circular Economy (CE) and Environmental, Social, and Governance (ESG) frameworks—a connection that remains ambiguous in both academic literature and practical application. This lack of clarity hinders corporate accountability and progress toward sustainability goals. To address this, we examine how CE and ESG intersect by integrating relevant theories and practical approaches. We identify key strategic overlaps across diverse CE and ESG indicators and frameworks, demonstrating how each can inform and strengthen the other. We begin by outlining foundational theories and current practices in both CE and ESG, then explore how their integration can enhance organisational alignment and accountability, particularly in the environmental dimension of ESG. To support this synergy, we propose an updated 10-R framework for qualitative reporting, incorporating new dimensions such as Regeneration (e.g., Rewilding and Restoration) to reflect biodiversity considerations. Additionally, we introduce the Circularity Scoring Model (CSM) to assess organisational CE performance concerning ESG objectives quantitatively. Our findings suggest that embedding CE principles into accounting and investment practices can highlight opportunities for improvement, such as transitioning to renewable energy, sourcing alternative materials, extending product lifespans, enhancing repairability, minimising waste, and increasing use of recycled or regenerative resources.

This research addresses the importance of sustainability in shipping beyond fuel selection, stressing the need for responsible material usage in vessel construction and maintenance. Transitioning to a circular economy is crucial for sustainable waste management in the industry, yet current ship design neglects circularity considerations, prioritising functionality and cost. The research evaluates frameworks such as the butterfly diagram, Cradle-to-Cradle, 10R, and ReSOLVE to integrate circularity into ship design. Combining the 10R framework with the Material Circularity Indicator method, this study offers practical insights for circularity in ship design. Challenges include integrating these methods into standard design processes, which are mitigated by fusing 10R strategies with systems engineering. A case study on wheelhouse redesign demonstrates the effects of this approach, highlighting the importance of supplier collaboration for circularity enhancement.
