The smart city has been a growing utopia, a brilliant image of a city of the future, in the past twenty years. Since its birth, at the end of the previous century, several changes have been seen in urban areas, both aligned and detached from this concept. On the one side, digital implementation seems to be growing in all the major cities, especially in the service sector, which are experiencing a proliferation of new solutions, tools and modalities of interactions. On the other side, new concepts are rising such as the “digital twin”, the “15-minute city”, and the “metaverse city”, evidencing both the necessity to continuously innovate and reach higher levels of digitalization but also the need to focus on people’s life. This paper aims to provide a contribution to the understanding of the concept’s evolution at the forefront of climate change with the aim to detect the elements of innovation, focusing on implementation roadmaps and trends but also searching for evolutions in research due to the COVID-19 pandemic. The hypothesis is that some changes of direction could have been triggered by the pandemic due to the urgency of finding concrete solutions. The conclusions will show that it is possible to detect some of them, especially in the technological domain.

Smart Cities have emerged as a promising approach for transforming urban living into more sustainable and resilient systems through technology-driven innovations and data-driven governance. Despite its growing implementation and diffusion around the globe, many questions surrounding this topic have emerged. Many critics have emerged since its first conceptualization in the first decade of the current century. Smart Cities have been criticized for their utopian objectives and the security, safety, people’s freedom, and privacy within these systems. There are also capitalistic and neoliberalism-related critiques. Other critiques also highlight the current climate cost of Smart City initiatives. In the context of those critiques, bioclimatic and passive strategies might provide an interesting evolution of the concept but seem to be left in the background. This paper aims to contribute to the understanding of the linkages between environmental design approaches and the Smart City discourse. The contribution will explore to which extent bioclimatic and environmental design principles are present in the Smart City discourse and what the patterns are inside the current literature. The methodology of the research included a quali-quantitative analysis of the body of literature in Scopus and a bibliometric analysis using the VOS Viewer tool.

Urban adaptation and resilience are essential aspects of climate change. The latest IPCC reports of 2022 recall the importance of taking concrete actions, especially through the implementation of actions able to make cities more resilient. However, the current scientific discourse predominantly revolves around policies, theoretical aspects and specific case studies. This study aims to provide an updated analysis of the existing scientific literature, with an additional focus on the role of assessment and monitoring frameworks in urban adaptation. By employing qualitative and quantitative methodologies, supported by VOSviewer for co-occurrence network analysis, this paper reveals novel clusters and thematic groupings within the ongoing debate. Results include the identification of new clusters and thematic grouping and the identification of potential future trends.

Renewable energy has a crucial role in facing climate change. One promising strategy is the creation of energy communities that require active involvement from a bottom-up perspective. Their implementation is difficult, as they currently rely on local policies, community readiness, and technological availability. The objective of this paper is to provide a qualitative overview of energy community concepts and strategies at the European level. The aim is to identify common approaches that are framing the development of energy communities, and to understand the most successful steps leading to their creation and growth. To achieve this objective, a threefold methodology is provided: (1) an updated review on policies dealing with energy communities at the European and Italian level; (2) a qualitative overview of European-funded projects under the Horizon 2020 work program; and (3) a qualitative overview of some of the most successful existing energy communities in Europe. The results outline a series of considerations and lessons learned that are useful for implementing this transition pathway in a real case, which is also presented in the paper. The conclusions will identify some future directions of this research, particularly in relation to the results coming from the implementation of actions in the real case.

Climate change and its challenges have long been incorporated into the policy-making process. Advocacy actions urge to strengthen the socio-ecological resilience through engagement with stakeholders, feedback recollection, and testing of solutions. Several initiatives have been born to boost cities’ actions toward climate change mitigation and adaptation. Institutional coordinated actions such as transnational municipal networks (TMNs) and non-institutional, grassroots movements for climate action, are among them. The study focuses on four TMNs and two grassroots movements, which have an impact on the European and/or worldwide contexts. They are investigated qualitatively, reflecting on the roles and contributions to climate change that they provide both alone and together. The research questions focus on the instruments/elements/factors that they put in place to support the transition, the key messages, and how these are conferred to their key targets. The initiatives have been investigated in both the grey and scientific literature. The main results show that grassroots movements for climate action and TMNs have the potential to better support cities in their climate transition. However, local governments are urged to take advantage of both initiatives’ ability to develop networks of support, innovation and a sense of belonging. In conclusion, the research states that the two initiatives should be effectively connected and integrated with a complementary role concerning planning actions.

The transfer of knowledge between universities and civil society is crucial in addressing the challenges of climate transition. This paper explores how municipalities and universities can act as co-producers of innovation, engaging in collaborative research and decision-making processes that directly support policy decisions and ensure continuous coordination of territorial actions. Given the increasing urgency of the climate crisis, a systemic, multi-level, and collaborative approach to urban governance is essential. The paper presents findings and reflections from the European project Let’s GOv, which supports nine Italian municipalities participating in the 100 Climate Neutral and Smart Cities Mission in accelerating their transition to climate neutrality.

Analyzing data from the Energy Poverty Observatory in Europe, it emerges that more than 50 million households in the EU live in energy poverty (people that cannot heat their homes during winter; cannot make their homes comfortable during the summer; pay their energy bills late). Research studies realized in the last 20 years highlight that making energy demand efficient and effective is the more significant and socially important the more it is able to involve users who are unable to sustain energy demand. The evolution of the research sees a narrowing of the field of investigation by focusing on the user dimension of energy poverty, stressing the role of citizens not only as consumer but also as producers of solutions to tackle energy poverty, real energy communities of agents. The paper aims to provide a systematic literature review highlighting the major findings of the topic, investigating the relationship between spatial and social issues, and looking at the state of energy poverty by addressing the profiling of users and consequently of services useful to overcome their current vulnerable condition. The paper is structured in two core sections. The first one gives the results of a systematic literature review on the energy/fuel poverty topic, the second one deepens the role of communities and individuals need, crucial in defining new design approaches for supportive solutions to tackle energy poverty.

The European energy transition is currently emphasizing advancements in regulations and technologies, with a focus also on social justice. Citizens are perceived as key players in the energy systems, as their direct involvement can contribute to the wide spread of improved behaviours and clean energy production. This paper explores Community Transition Pathways (CTPs), an innovative instrument to support energy citizenship effectively. CTPs guide citizens through structured paths, addressing diverse communities. Grounded in energy citizenship theories, the concept integrates insights from literature and policy developments. CTPs have been created within the H2020 project GRETA and verified in six case studies across Italy, Spain, Germany, the Netherlands, and Portugal. This paper aims to present the instrument as a project result, embedding its creation in the current debate about energy citizenship and transition pathways and presenting the results on three GRETA case studies. The research’s originality lies in its empirical approach, emphasizing citizens’ active roles in transition processes. Successful development and testing of CTPs demonstrate their value in fostering collaboration in clean energy production and facilitating participatory transition paths. However, ongoing refinement and replicability are essential for sustained success. By positioning citizens as active participants and reshaping public decision-making, CTPs advance a more inclusive and impactful approach to energy transition.

Responses to the current energy crisis and to action against climate change have produced a wide variety of experimentations. Positive Energy Districts (PEDs) and Energy Communities (EC) are spreading as aggregators of enabling technologies, but the knowledge and skills required to plan, implement and monitor them still need to be developed. Technology alone is not enough to facilitate knowledge sharing and the experimentation and co-creation of solutions. The paper focuses on methods and tools that allow to support the creation of “energy citizens” through considerations developed in project H2020 GRETA (Green Energy Transition Actions) and in COST Action ‘PED-EU-NET’.

The promotion of participatory processes in initiatives such as Energy Communities (ECs) can prompt behavioural change in ecological transition. The paper presents the experience of the Municipality of Cesena and the University in the EN-ACTION project aimed at increasing awareness among students and citizens about energy transition through initiatives involving various stakeholders. The first section outlines the state of the art on energy citizenship and universities in ecological transition. The methodological section illustrates the participatory approach of EN-ACTION. The third section describes the results. The conclusions emphasise the central role of active citizenship in the transition, and the role of the public in shared management of energy.
