<abstract>
<p>This study explores the implementation of Urban Living Labs (ULLs) in Higher Education Institutions (HEIs) to promote Education for Sustainable Development (ESD). It adopts a methodology that integrates a mixed approach, combining literature review, validation with experts in the field and analysis of case studies. A structured evaluation tool is proposed based on three constructs: Synergy, Strategy and Pedagogy, which cover the essential characteristics of the three thematic axes: ULLs, ESD and HEIs, through seven indicators. This tool is applied to examine the effective-ness of ULLs in promoting sustainable practices within the university context. The results, vali-dated through experts, exploratory factor analysis and Cronbach&#x2019;s alpha coefficient, demonstrate the reliability and consistency of the evaluative indicators, highlighting the crucial role of ULLs in the integration of sustainability in the curriculum, experiential learning, and the impact social and community. This approach allowed the identification of successful practices and common challenges in the implementation of ULL, as well as the development of a framework of indicators adapted to the specific needs of HEIs. The study concludes by emphasizing the transformative potential of ULLs in HEIs to advance towards sustainable urban transitions, underscoring the need for robust evaluative tools to optimize the contribution of higher education to global sustainable development.</p>

<title>1 Introduction</title>
<p>In a constantly evolving world, humanity faces contemporary challenges such as economic, social and environmental sustainability. This underlines the pressing need for governments, private enterprise and professionals to attain new knowledge and skills towards sustainability. In this context, education becomes an essential tool to achieve the comprehensive sustainable development of society, so much so that UNESCO recognizes education as one of the Sustainable Development Goals (SDGs), focusing on ensuring inclusive and quality education (SDG 4). Specifically, target 4.4 emphasizes the importance of equipping students with skills for sustainable development. ESD is defined as an educational approach that seeks to integrate sustainable development principles, values and practices into all aspects of education and learning. This approach aims to empower students to actively contribute to a more sustainable, equitable and just world by promoting a shift in awareness and action towards sustainability (<xref ref-type="bibr" rid="B52">Organizaci&#x00F3;n de las Naciones Unidas para la Educaci&#x00F3;n [UNESCO], 2017</xref>; <xref ref-type="bibr" rid="B56">Rieckmann, 2017</xref>).</p>
<p>HEIs play a crucial role in promoting sustainability, not only because of their ability to influence future leaders and professionals, but also because of their role as models of sustainable practices within their own communities (<xref ref-type="bibr" rid="B16">Cortese and Hattan, 2010</xref>; <xref ref-type="bibr" rid="B55">Purcell et al., 2019</xref>; <xref ref-type="bibr" rid="B26">Hern&#x00E1;ndez-Diaz et al., 2021</xref>). HEIs become centers of knowledge creation and transfer to society through research and teaching (<xref ref-type="bibr" rid="B64">Segal&#x00E0;s, 2019</xref>). The transition towards sustainability in HEIs is complex, requiring profound reorganization and redefinition in order to be effective in their role as agents of change (<xref ref-type="bibr" rid="B71">Tilbury, 2011</xref>; <xref ref-type="bibr" rid="B39">Lozano et al., 2013</xref>; <xref ref-type="bibr" rid="B58">Rotondo et al., 2023</xref>). HEIs should focus on principles of responsibility and sustainability, seeing themselves as laboratories in which students learn to critically examine social conditions, develop ideas for a better future and implement sustainable solutions (<xref ref-type="bibr" rid="B6">Bauer et al., 2021</xref>). This involves not only integrating sustainability into the curriculum, but also into research, campus operations and community outreach (<xref ref-type="bibr" rid="B37">Leal Filho et al., 2019</xref>; <xref ref-type="bibr" rid="B50">Mori et al., 2019</xref>; <xref ref-type="bibr" rid="B67">Skanavis et al., 2020</xref>).</p>
<p>Adopting a holistic and collaborative approach is fundamental to the successful implementation of ESD. This means addressing sustainability through an interdisciplinary and transdisciplinary perspective that engages multiple stakeholders and disciplines, recognizing the interconnectedness between economics, ecology and human/social well-being (<xref ref-type="bibr" rid="B81">Wals, 2014</xref>; <xref ref-type="bibr" rid="B82">Withycombe Keeler et al., 2016</xref>; <xref ref-type="bibr" rid="B42">Masseck, 2017</xref>; <xref ref-type="bibr" rid="B24">Greve et al., 2020</xref>; <xref ref-type="bibr" rid="B22">Finnveden et al., 2022</xref>). Reframing knowledge in multiple contexts and dimensions requires innovative teaching and learning strategies (<xref ref-type="bibr" rid="B7">Bindal, 2022</xref>). The Quintuple Helix model is an example of how HEIs can foster effective collaboration between academia, industry, government, society and the environment, thus promoting innovation and knowledge for sustainable development (<xref ref-type="bibr" rid="B12">Carayannis and Campbell, 2021</xref>, <xref ref-type="bibr" rid="B11">2010</xref>).</p>
<p>Furthermore, ESD in HEIs must transcend the traditional paradigm of knowledge transmission, promoting a pedagogical shift towards more interactive learning, where educators and students are co-learners in a process of joint exploration (<xref ref-type="bibr" rid="B69">Sterling and Orr, 2001</xref>; <xref ref-type="bibr" rid="B66">Sinakou et al., 2022</xref>). This involves creating spaces for critical dialogue and reflection on values, ethics and social responsibility, essential elements for fostering sustainable awareness and action. By embracing ESD, HEIs not only prepare students to face the challenges of the future, but also position themselves as leaders in the transformation towards a more sustainable society (<xref ref-type="bibr" rid="B49">Moreno et al., 2015</xref>; <xref ref-type="bibr" rid="B25">Henr&#x00ED;quez Guajardo, 2018</xref>).</p>
<p>In this context Urban Living Labs (ULLs) represent an innovative paradigm in urban research and development, serving as experimental platforms to design, test and learn about sustainable urban solutions in real-life contexts (<xref ref-type="bibr" rid="B9">Bylund et al., 2022</xref>). These living labs are defined by their participatory approach, where actors from diverse sectors collaborate to co-create innovations that address complex urban challenges, embedding sustainability into the fabric of everyday life (<xref ref-type="bibr" rid="B8">Bulkeley et al., 2016</xref>). By situating experimentation in real urban environments, ULLs provide fertile ground for applied research, collaborative learning and citizen engagement in sustainable innovation processes (<xref ref-type="bibr" rid="B65">Sengers et al., 2019</xref>; <xref ref-type="bibr" rid="B33">Korzer et al., 2020</xref>; <xref ref-type="bibr" rid="B77">Von Wirth et al., 2020</xref>; <xref ref-type="bibr" rid="B57">Rizzo et al., 2021</xref>; <xref ref-type="bibr" rid="B63">Scholl and de Kraker, 2021</xref>; <xref ref-type="bibr" rid="B53">Pa&#x00E7;o and Azeiteiro, 2022</xref>). These living laboratories have become catalysts for sustainable change, facing real dilemmas in delineated geographical settings (<xref ref-type="bibr" rid="B41">Marvin et al., 2018</xref>; <xref ref-type="bibr" rid="B61">Sch&#x00E4;pke et al., 2018</xref>; <xref ref-type="bibr" rid="B78">Von Wirth et al., 2019</xref>).</p>
<p>The incorporation of ULLs in HEIs presents a unique opportunity to move towards ESD. ULLs can serve as experiential teaching-learning strategies, providing students and academics with a real laboratory in which to apply sustainability theories, evaluate innovative solutions and reflect on their socio-ecological impact (<xref ref-type="bibr" rid="B20">Evans et al., 2016</xref>; <xref ref-type="bibr" rid="B76">Verhoef et al., 2020</xref>). This practical and contextualized approach fosters the development of key competences for sustainable development, such as critical thinking, complex problem solving and interdisciplinary collaboration skills (<xref ref-type="bibr" rid="B51">O&#x2019;Brien et al., 2021</xref>).</p>
<p>Furthermore, ULLs facilitate a deeper connection between HEIs and their communities, aligning education and research with local needs and challenges. By engaging students, academics, industry, government and citizens in the co-design of sustainable solutions, ULLs promote meaningful learning that transcends the boundaries of the classroom, encouraging social responsibility and civic engagement (<xref ref-type="bibr" rid="B45">McCormick and Hartmann, 2017</xref>; <xref ref-type="bibr" rid="B1">Amorim et al., 2020</xref>). This multidimensional collaboration not only enriches the educational experience, but also contributes to the creation of innovative and contextualized solutions, increasing the relevance and impact of ESD.</p>
<p>The implementation of ULLs as a teaching-learning strategy in HEIs towards ESD requires an integrated institutional approach that promotes interdisciplinarity, collaboration and project-based learning. The creation of physical and virtual spaces dedicated to sustainable experimentation enables students and academic staff to actively participate in applied research and the development of sustainable solutions, preparing them to face the challenges of sustainable development in their future professional careers and personal lives (<xref ref-type="bibr" rid="B83">Wolff, 2020</xref>).</p>
<p>However, despite their rising importance and potential impact on promoting ESD, a gap has been revealed in the scientific literature. Surprisingly, there is a lack of attention to the systematic and effective evaluation of ULL as a strategy for ESD in HEIs (<xref ref-type="bibr" rid="B48">Morales et al., 2023</xref>). Studies of Living Labs (LL) such as LOW3 (<xref ref-type="bibr" rid="B42">Masseck, 2017</xref>) at the Polytechnic University of Catalonia (UPC), a prototype solar house that functions as a platform for teaching, research and innovation, or Carleton University&#x2019;s case of a building as LL (<xref ref-type="bibr" rid="B51">O&#x2019;Brien et al., 2021</xref>), describe experiences and findings, but do not present a project evaluation methodology with respect to ESD. The same is true for ULLs at the University of Manchester (<xref ref-type="bibr" rid="B19">Evans et al., 2015</xref>), Massachusetts Institute of Technology (MIT) (<xref ref-type="bibr" rid="B83">Wolff, 2020</xref>), University of Southern Santa Catarina (<xref ref-type="bibr" rid="B1">Amorim et al., 2020</xref>). This gap translates into an opportunity to improve our understanding of how ULLs can be designed and operated as effective tools for promoting sustainability.</p>
<p>Several studies, such as (<xref ref-type="bibr" rid="B79">Voytenko et al., 2016</xref>), underline the need to develop standardized tools to compare urban laboratories in different contexts, facilitating shared learning among ULLs (<xref ref-type="bibr" rid="B68">Steen and Bueren, 2017</xref>) emphasize the importance of common methodologies to maintain consistency in the assessment of these labs. (<xref ref-type="bibr" rid="B8">Bulkeley et al., 2016</xref>) highlight how a unified methodological framework can significantly improve efficiency in the implementation and assessment of these labs. According to (<xref ref-type="bibr" rid="B4">Baccarne et al., 2014</xref>), a standardized methodology gives transparency and credibility to ULLs, while (<xref ref-type="bibr" rid="B41">Marvin et al., 2018</xref>) emphasizes the importance of a common framework to ensure the strategic relevance of ULLs in the context of sustainable cities. This underlines the fundamental importance of having a standardized methodology for assessing ULLs as tools for ESD in HEIs, as it allows for effective comparison of ULLs in different contexts and geographies, facilitating analysis and identification of successful practices that can be replicated. It also provides a common framework for assessing all ULLs in a consistent way, resulting in reliable data and objective assessments, which are essential for measuring progress, identifying weaknesses and improving strategies. It also promotes the sharing of findings and results among HEIs and other stakeholders, fostering collective learning and contributing to continuous improvement. Finally, it facilitates the implementation of ULLs, saving time and resources, allowing HEIs to focus on the impact they want to achieve, and providing transparency and credibility to ULLs, which increases their strategic relevance and contributes significantly to HEIs&#x2019; sustainability goals.</p>
<p>This lack of attention to the systematic and effective evaluation of ULL as a strategy for ESD in HEIs translates into an opportunity to improve our understanding of how ULLs can be designed and operated as effective tools to promote sustainability. This research therefore focuses on addressing this gap by developing a specific assessment tool to reveal and measure the role of ULLs in promoting ESD in HEIs. Measuring and understanding the role of ULLs in transforming our societies towards a more sustainable future is of paramount importance, and this tool aims to provide a solid basis for its evaluation and continuous improvement.</p>

<label>&#x2022;</label>
<p>Phase 1: Identification of dimensions and approach to indicators</p>
</list-item>
</list>
<p>In this phase, through an exhaustive literature review using the SALSA (Search, Appraisal, Synthesis and Analysis) methodology (<xref ref-type="bibr" rid="B23">Grant and Booth, 2009</xref>), the key dimensions to be considered in the evaluation of ULL concerning ESD in HEIs were identified. The approach was based on the main characteristics of the three thematic axes ULL, ESD and HEIs and their relationship to each other. For each dimension an indicator was developed including description, assessment method and interpretation of results. <xref ref-type="supplementary-material" rid="DS1">Supplementary Appendix 1</xref> shows an outline of the literature review based on the SALSA methodology.</p>
<list list-type="simple">
<list-item>
<label>&#x2022;</label>
<p>Phase 2: Validation through experts</p>
</list-item>
</list>
<p>The dimensions and indicators from phase 1 were analyzed with a panel of seven experts for validation. The panel consisted of professionals with expertise in the areas of education and sustainable development, research methodology, ULL and academics from HEIs. These experts assessed each of the dimensions and indicators in terms of relevance, clarity and applicability using a three-point Likert scale. In the case of the indicators that were not scored with the maximum value, the reasons for this were discussed. The expert validation format is shown in <xref ref-type="supplementary-material" rid="DS1">Supplementary Appendix 2</xref>. Adjustments were made according to the comments and suggestions of the experts, and the dimensions and indicators were changed or refined. The process of exchanging information with the experts was carried out via email and video calls. All stages of the process were socialized with the experts in order to receive the respective feedback.</p>
<list list-type="simple">
<list-item>
<label>&#x2022;</label>
<p>Phase 3: Validation through statistical methods</p>
</list-item>
</list>
<p>Using the SALSA methodology (<xref ref-type="bibr" rid="B23">Grant and Booth, 2009</xref>), a representative sample of ULL projects involving HEIs was selected. Projects of various geographical regions and sizes was included, ensuring a variety reflecting different contexts and approaches of ULLs. Data were collected through the projects&#x2019; records on their websites and published scientific articles. This information was used to assess each of the indicators validated in Phase 2.</p>
<p>To confirm the structural validity of the dimensions and indicators, Exploratory Factor Analysis (EFA), (<xref ref-type="bibr" rid="B44">Mavrou, 2015</xref>) was used, considering factor loadings greater than 0.722 for sample sizes <italic>n</italic> = 50 as significant. This analysis helped to confirm whether the proposed dimensions were adequately reflected in the indicators. To assess the reliability of the indicators, Cronbach&#x2019;s alpha coefficient was calculated (<xref ref-type="bibr" rid="B3">Avecillas and Lozano, 2016</xref>). A value above 0.7 is considered indicative of high internal consistency. All analyses were conducted using the freely licensed software R, (<xref ref-type="bibr" rid="B34">Kronthaler and Z&#x00F6;llner, 2021</xref>). Correlations between indicators were examined to validate their relevance and effectiveness in measuring aspects of ESD in ULLs. The results allowed us to adjust or reaffirm the validity of the proposed indicators. In those cases, where the results indicated the need for revision, adjustments were made by redefining or eliminating them to ensure that they accurately reflect the interaction between ULLs and ESD in HEIs.</p>
<list list-type="simple">
<list-item>
<label>&#x2022;</label>
<p>Phase 4: Interpretation and representation of results</p>
</list-item>
</list>
<p>Considering the criteria of uniformity and reduction of bias, it was assumed that all validated indicators are of equal importance for the promotion of ESD in HEIs, therefore the sum of the indicators was taken as the total project rating. If there are n projects in a ULL, the average of the n projects corresponds to their total rating. In a scale of interpretation of the results, the aim was to explain the situation of the ULL project about the ESD in a simple way, for which the Likert methodology was used (<xref ref-type="bibr" rid="B43">Matas, 2018</xref>).</p>
<p>For the representation, data visualization tools were used to create graphical representations of the results. This included graphs and diagrams that helped to interpret the data in an intuitive and accessible way.</p>

This analysis is enriched by the work of Steen and Bueren, who, after studying ninety projects, identify nine essential characteristics of ULLs in four dimensions: objectives, activities, participants and context (<xref ref-type="bibr" rid="B68">Steen and Bueren, 2017</xref>) and by <xref ref-type="bibr" rid="B79">Voytenko et al.

<p>In all cases the factor loadings are significant, values greater than 0.722 for sample sizes <italic>n</italic> = 50. The SDPI, IDI, and COII indicators have high factor loadings on the ML1 factor, suggesting that they represent a common construct. The indicators COI and RSI have high factor loadings on the ML2 factor, indicating that they are closely related and represent another distinct construct. The indicators CIIU and LRII have high factor loadings on ML3, suggesting that these indicators represent a third construct. The proportion of variance explained by each factor (ML1, ML2, and ML3) is 30.4, 23.9 and 23.3%, respectively, for a cumulative total of 77.6%.

<p>Based on the results of the EFA and Cronbach&#x2019;s alpha coefficient, the distribution of indicators is made under three identifiable constructs in the analysis: Synergy, Strategy and Pedagogy. The following describes each of them.</p>
<list list-type="simple">
<list-item>
<label>&#x2022;</label>
<p>Synergy: It covers how interaction and cooperation between different sectors (SDPI) and disciplines (IDI) can have an effective impact on the community (COII), achieving results that go beyond what each could achieve individually.</p>
</list-item>
<list-item>
<label>&#x2022;</label>
<p>Strategy: It encompasses both clarity and precision in defining objectives (crucial aspect of COI) and the ability to achieve sustainable and far-reaching results (core of RSI).</p>
</list-item>
<list-item>
<label>&#x2022;</label>
<p>Pedagogy: Covers both the integration of new knowledge and approaches into the curriculum (CIIU) and the impact on learning and research (LRII).</p>
</list-item>
</list>
<p>These constructs are fundamental to understanding how interaction and cooperation between different sectors and disciplines can effectively impact the community, the importance of having clear and precise objectives to achieve sustainable and long-range results, and how the integration of new knowledge and approaches in the curriculum affects learning and research.</p>
</sec>
<sec id="S3.SS4.SSS6">
<title>3.4.6 Interpretation and representation</title>
<p>The overall evaluation of the project is obtained through the sum of the seven indicators; therefore, the maximum possible evaluation is 14 points. The mechanism for interpreting the results corresponds to a four-point Likert scale. It should be stressed that an accurate interpretation will depend on the specific results of each indicator, thus allowing for a more comprehensive analysis of the strengths and weaknesses of the project.</p>
<p>(0&#x2013;5): In this range, the project shows very low performance on most or all of the indicators assessed.</p>
<p>(5&#x2013;8): In this range, the project demonstrates low to moderate performance on most indicators. Although there may be areas for improvement, some dimensions of the project may be performing acceptably.</p>
<p>(8&#x2013;11): In this range, the project shows moderate to high performance on most indicators. This suggests that the project is achieving satisfactory results in most of the areas assessed.</p>
<p>(11&#x2013;14): In this range, the project demonstrates high performance on all or most indicators. This indicates that the project is performing excellently in promoting sustainability in HEIs.</p>
<p>The graphical representation in the form of a stacked bar chart allows visualizing the results of the individual indicators and the total project rating, which facilitates comparison between projects. An example is presented in <xref ref-type="fig" rid="F2">Figure 2A</xref>.</p>

<title>4 Discussion</title>
<p>In the field of ESD in HEIs, ULLs present themselves as innovative tools that seek to effectively integrate sustainability principles into university education. Several ULL projects in university contexts have demonstrated their potential to foster pedagogical innovation, active student participation and interdisciplinary collaboration. Despite their growing adoption, the scientific literature reveals a significant gap: the lack of a standardized methodology to assess the impact and effectiveness of ULLs as strategic tools in the educational context (<xref ref-type="bibr" rid="B48">Morales et al., 2023</xref>). Several studies such as (<xref ref-type="bibr" rid="B79">Voytenko et al., 2016</xref>; <xref ref-type="bibr" rid="B68">Steen and Bueren, 2017</xref>; <xref ref-type="bibr" rid="B41">Marvin et al., 2018</xref>) and others highlight the importance of developing standardized methodologies to evaluate and compare ULLs, which would improve their efficiency, credibility and strategic relevance, fostering shared learning and their impact on sustainable development.</p>
<p>LL and ULLs exhibit a rich methodological diversity. Projects such as LOW3 at the Universitat Polit&#x00E8;cnica de Catalunya (<xref ref-type="bibr" rid="B42">Masseck, 2017</xref>), focused on the co-creation of sustainable solutions in architecture, and the Malm&#x00F6; Innovation Platform (MIP) at Lund University (<xref ref-type="bibr" rid="B46">McCormick and Kiss, 2015</xref>), which offers both virtual and physical participatory learning environments in building renovation, demonstrate this varied approach. Carleton University (<xref ref-type="bibr" rid="B51">O&#x2019;Brien et al., 2021</xref>) uses Experiential Learning Theory for teaching in building engineering, while ULL at the University of Manchester (<xref ref-type="bibr" rid="B19">Evans et al., 2015</xref>) and MIT (<xref ref-type="bibr" rid="B83">Wolff, 2020</xref>) are notable for transforming the academic environment into a dynamic space for hands-on learning in sustainability. However, they reflect a plethora of approaches and objectives that, while valuable, make benchmarking difficult. The lack of unified criteria limits the ability of HEIs to measure ULL&#x2019;s impact on ESD. Although a general evaluation framework is proposed based on key aspects such as impact on teaching and sustainable learning, its practical application is challenging due to the uniqueness of each project.</p>
<p>The current status of ULLs in ESD shows great potential, but a standardized evaluation methodology is needed to accommodate the diversity of contexts and approaches, providing clear and consistent criteria for measuring their impact on ESD. This will enable HEIs to demonstrate the value of ULLs and harness their potential, effectively integrating sustainability into higher education.</p>
<p>This study addresses this gap by proposing a structured assessment tool to understand and quantify the role of ULLs in promoting ESD in HEIs. The standardized methodology aims to ensure consistency, comparability, shared learning and efficiency, providing a structured framework to facilitate implementation and evaluation, bringing transparency and credibility to the results obtained. This tool is not proposed as the only solution for developing ULLs, but as a framework to expand knowledge and guide the development of ULLs towards ESD in HEIs.</p>
<p>The design of the tool started from the theoretical analysis of the close relationship between the characteristics of ULLs, ESD and HEIs to identify the relevant dimensions towards sustainability. Initially, the literature review identified ten relevant dimensions which, through analysis and input from a panel of experts, were synthesized into seven. Subsequently, the results of the Exploratory Factor Analysis (EFA) suggested a more refined grouping of these indicators into three constructs: Synergy, Strategy and Pedagogy. This process of conceptual clarification and refinement is essential to ensure that the study accurately addresses the most influential and manageable elements in promoting ESD through ULLs.</p>
<p>This reorganization of the indicators into the three constructs reflects a more integrated and holistic view of ESD promotion in HEIs. It recognizes that: Clear and well-defined goals are the basis for long-term sustainable practices (Strategy). Participation and collaboration among various disciplines and actors, including the targeted community, are crucial for the successful and sustainable implementation of ESD initiatives (Synergy). Curricular integration and impact on learning and research are key elements of ULL effectiveness in academia (Pedagogy).</p>
<p>Each of the seven proposed dimensions has significant implications for sustainable development in HEIs, focusing on key aspects such as the alignment of objectives with ESD principles and the inclusion of diverse actors to address asymmetries of power and knowledge in sustainability projects. The integration of perspectives, knowledge and methodologies is essential for a holistic approach, while curriculum integration and experiential learning foster real-world problem solving, applied research and critical skills development, as well as understanding of sustainability challenges. In addition, strengthening the decision-making power of communities and ensuring that initiatives do not reproduce existing inequalities, along with assessing resource management and promoting sustainable practices, are essential.</p>
<p>The methodology is validated through reliability analysis, showing internal consistency in all indicators used. Although it involves a certain degree of subjectivity, the process of involving ESD and ULL experts, together with the use of robust statistical methods, ensures the relevance and pertinence of the assessment framework.</p>
<p>The evaluation of various types of projects in different contexts has validated the applicability of the tool, demonstrating the flexibility of the model. However, it faces practical challenges in terms of applicability and usefulness, as its effectiveness depends on access to accurate information and user training in ESD. In addition, the implementation of the model requires considerable time and analytical resources from institutions. Although it is designed to benefit ULL project leaders in their quest for continuous improvement, its ultimate usefulness lies with the entire educational community.</p>
<p>The tool provides a uniform framework for measuring the impact of ULLs, facilitating meaningful comparisons between labs with different approaches and context. This framework allows comparison of their impact in key areas, such as curriculum integration, resource use and community impact, among others. Some of the observations found in the evaluations are described below.</p>

<title>5 Conclusion</title>
<p>The study addresses a gap in the scientific literature on the systematic evaluation of ULLs as tools to promote ESD in HEIs. It provides a structured evaluative tool to understand and quantify the role of ULLs in this context, emphasizing their relevance given the growing importance of sustainability.</p>
<p>The research successfully validated seven key dimensions and their respective indicators for assessing ULL in the framework of ESD in HEIs. These dimensions cover crucial aspects such as objectives and scope, stakeholder participation, interdisciplinarity, curricular integration, experiential learning and research, community impact, and resources and sustainability.</p>
<p>Through Exploratory Factor Analysis (EFA) and Cronbach&#x2019;s alpha coefficient test, the study demonstrated a refined grouping of indicators into three constructs (Synergy, Strategy and Pedagogy) and confirmed a high reliability and internal consistency of the indicators.</p>
<p>The proposed methodology, which includes literature reviews, expert validation and statistical methods, provides a robust and structured guide for the assessment of ULLs. Despite some practical challenges, the model demonstrates flexibility and potential to adapt to various project contexts.</p>
<p>The evaluation results highlight the great potential of ULLs to drive innovation and sustainability in HEIs. However, their success depends on effective management of multi-stakeholder collaboration, integration into curricula and adequate assessment of community impact. Challenges include overcoming institutional barriers, securing sustainable funding and effectively managing power differentials between stakeholders.</p>
<p>Overall, this study provides a significant advance in the understanding and evaluation of ULLs in the framework of ESD in HEIs, offering a solid foundation for future research and practice in this evolving field.</p>
<p>The proposed model offers significant opportunities for further expansion. Its validation and application in a diverse range of educational, cultural and business settings in different geographical regions would not only deepen the understanding of ULLs in promoting ESD, but could also highlight the need to adapt and refine the model, thus enhancing its relevance and applicability in a global context.</p>
<p>Ultimately, such an expanded approach would allow for a more inclusive and representative assessment of ULLs, paving the way for a more meaningful impact on educational sustainability globally.</p>
