Over the past few years, energy communities initiatives have gained traction in Europe as a means to achieve energy transition goals, allowing citizen involvement in energy production, consumption, and distribution. Following the 2018 European directive RED II, these projects have rapidly increased across the continent, showcasing their potential for creating sustainable local energy systems. While studies highlight economic, environmental, and social benefits, barriers such as regulatory challenges, finance access, and low public awareness remain. This paper presents the results of a systematic literature review that explores the state-of-the-art of the academic research on energy communities. The study adopts a systematic approach to examine the body of literature on the topic to provide a comprehensive analysis of the phenomenon on the basis of rigorous and replicable research criteria. The reviewed material consists of 140 articles collected through the Scopus database, evaluated using specific structural dimensions to group the literature into analytical categories. The analysis of scientific papers published between 2018 and 2022 shows a growing attention towards Renewable Energy Communities, particularly those based on solar energy for electricity production, often combined with storage systems and heat pumps, whereas attention towards energy communities based on thermal energy production is still limited. Furthermore, most scholars focused on analysing specific territorial contexts; comparisons between different regions allows to highlight common features and elements characterizing each model. It emerged that the development of energy communities depends mainly on regulatory, financial, and managerial barriers that require an adequate institutional and legal framework capable of promoting their diffusion. Most studies address the topic from an economic perspective, often in association with incentivizing community models. However, a social perspective should be included by introducing the concept of energy sharing and methodologies for its distribution among all members of the community. The scientific community is called upon to continue investigating and supporting the development of community energy initiatives by providing evidence-based recommendations to policymakers, industry stakeholders, and local communities. This can help to overcome existing barriers and facilitate the diffusion of energy communities models, contributing to the achievement of sustainable and inclusive energy transition goals. • Systematic literature review exploring academic research on energy communities in Europe. • Structural dimensions and related analytical categories as framework to review 140 journal articles. • Most studies concern ECs based on renewable energy sources, with solar power being the predominant source. • Most employed technologies are related to the production of electricity from photovoltaic with batteries and heat pumps. • Most studied focus on Renewable Energy Community, while Citizens Energy Community are less considered in academic studies.

Recent technological developments make perovskite solar cells (PSCs) particularly suitable for building integrated photovoltaic (BIPV) applications on vertical building envelopes, but the relatively short lifespan of PSCs requires frequent replacement, thereby generating substantial waste. Careful consideration of circularity credentials of this novel technology is therefore essential prior to the extensive implementation of vertical PSCs in building envelopes. This paper provides a circular economy approach for the implementation of PSCs in vertical envelopes and assesses its economic feasibility by life cycle cost analysis in Europe. The process of recycling PSC is developed. The economic performance of PSC envelopes is provided and compared to that of the conventional rigid BIPV system. Uncertainty analysis and sensitivity analysis of economic indicators are then performed to identify the influential parameters. The findings indicate that the PSC envelope has a significant potential for circular BIPV components and that PSCs applied on vertical envelope are economically viable. • LCCA of vertical PSC envelopes with recycling strategy is analyzed in Europe. • Recycling strategy of PSC is explored before diffusion to overcome PSC's short lifespan. • PSC price is the most influential factor for the deviation of LCOE. • PSC envelope has potential to achieve profitability in most regions of Europe.

The 2018 European bioeconomy strategy sets a new vision for Europe's sustainable development: a transition to regenerative resource usage that embraces circular principles. Similarly, various member states have developed national bioeconomy strategies. To be effective, such strategies require methodologically sound monitoring tools that support the alignment of national and urban policies. Indeed, cities are central to the bioeconomy, mobilizing ever increasing amounts of biogenic materials. To better understand the suitability of national bioeconomy strategies for guiding urban circular bioeconomy transitions, this paper examines the composition, features, and topical coverage of national bioeconomy indicator sets with a threefold analysis: (1) assessment of the integration of circularity principles in the sets and their alignment with existing policy frameworks; (2) appraisal of quality and the fulfillment of the sets' functional purposes; (3) evaluation of the breadth and depth of tackled issues. Of the 27 EU member states, only nine have a dedicated bioeconomy strategy, of which four propose an indicator set. While there is a general lack of sophisticated monitoring, the tools proposed after the publication of the 2018 bioeconomy strategy (Germany and Italy) follow indicator development standards rigorously. They include circularity in their notion of bioeconomy and combine indicators for a comprehensive, substantial, informative and politically relevant analysis. These characteristics strongly improve the potential for alignment and coherence with urban-level bioeconomy monitoring efforts. Although national measuring tools are not intended to cover all urban needs, the findings of this paper give insight into their remaining gaps and highlight improvement pathways for an efficient EU-wide circular bioeconomy transition. [Display omitted] • Most EU national bioeconomy strategies lack sophisticated indicator sets. • National bioeconomy strategies should favor alignment with other policy levels. • Thoroughly developed indicator sets allow targeted answers to environmental change. • Recent strategies follow indicator development standards more rigorously. • Recent indicator sets enable monitoring of urban circular bioeconomy transitions.

This paper describes a systematic literature review of how market-based instruments can influence the development of sustainable innovation. Our analysis of empirical papers published in selected peer-reviewed journals from 1992 to 2021 shows that contextual factors such as geography and industrial sector impact whether market-based instruments successfully stimulate firms to adopt sustainable innovation. Interestingly, while most of our selected papers on East Asia report positive effects of market-based instruments, about half of the papers on Europe report negative or non-significant effects. Moreover, we appear to uncover a link between the research method they use for analysis and the observed effectiveness of market-based instruments. We reflect on the limitations and bias in current methodological approaches and discuss explanations for our findings, implications for policymakers, and avenues for future research. • We review the effect of market-based instruments on sustainable innovation. • Results from 76 empirical papers show mixed effects. • The observed effect appears to depend on geography and the research method applied. • Instruments appear more effective in East Asia than in Europe. • Reported effectiveness is higher in studies using patent data versus surveys.

Due to the immense pressure of environmental pollution, economic growth and energy usage, green growth is recognized as the fundamental development strategy in Europe. This paper assesses environmental efficiency (ENE) of 54 industries from 28 European countries across the three sectors of an economy over the 2000–2014 period using a non-radial directional distance function (DDF). The aim of this study is to shed light and provide a deeper understanding of the different levels of technological heterogeneity that exist among industries by incorporating the metafrontier approach under distinct sector and country-specific production frontiers. The results reveal that industries present higher levels of environmental efficiency within their sectors while manufacturing industries achieve the lowest progress in environmental efficiency. Thus, it is critical to introduce and implement sector-oriented policies rather than common guidelines for all European countries. [ABSTRACT FROM AUTHOR]

Climate change impacts in one country can lead to impacts in distant locations, for example, via internationally traded crops. Previous work has highlighted a need to include cross-border climate change impacts in climate risk assessments, to describe the exposure and transmission of cross-border climate risk across actors, and understand options for managing this risk. In a case study of the Brazil-Europe soy supply chain, this paper aims to explore how stakeholders perceive past and future shocks, how climate change impacts affect stakeholders differently, and how they might respond. Soy is a key internationally traded commodity and Europe relies on imports for the majority of its soy consumption, used widely in livestock feed. Via 96 semi-structured expert interviews, we found different stakeholder groups are vulnerable to different types of weather shocks, experience different price and supply consequences, and have different capacities to respond. While some responses can reduce risk of impacts across the supply chain (e.g. new soy cultivars, improving transport infrastructure), we also identified examples where responses exacerbate risk for other stakeholders (e.g. export bans, changing demand). A holistic cross-border approach to analysing risk in the soy supply chain can help avoid maladaptation and offer opportunities for more collaborative adaptation. [ABSTRACT FROM AUTHOR]

[Display omitted] Energy transitions are at the top of global agendas in response to the growing challenges of climate change and international conflict, with the EU positioning itself as playing a pivotal role in addressing climate risks and sustainability imperatives. European energy transition policies identify 'smart consumption' as a key element of these efforts, which have previously been explored from a predominantly technical perspective thus often failing to identify or address fundamental interlinkages with social systems and consequences. This paper aims to contribute to interdisciplinary energy research by analysing a forward looking 'Horizon Scan' research agenda for smart consumption, driven by the Social Sciences and Humanities (SSH). Reflecting on an extensive systematic Delphi Method exercise surveying over 70 SSH scholars from various institutional settings across Europe, we highlight what SSH scholars see as future directions for smart consumption research. Building from seven thematic areas (under which are grouped 100 SSH research questions), the study identifies three key 'shifts' this new smart research agenda represents, when compared to previous agendas: (1) From technological inevitability to political choice , highlighting the need for a wider political critique, with the potential to open up discussions of the instrumentalisation of smart research; (2) From narrow representation to diverse inclusion , moving beyond the shortcomings of current discourses for engaging marginalised communities; and (3) From individual consumers to interconnected citizens , reframing smart consumption to offer a broader model of social change and governance. Social Sciences and Humanities scholarship is essential to address these shifts in meaningful (rather than tokenistic) ways. This agenda and the shifts it embodies represent key tools to enable better interdisciplinary working between SSH and teams from the technical and natural sciences. • Smart agenda deliberatively produced by 70+ Social Sciences and Humanities scholars. • 100 questions organised under seven SSH themes, which cut across technologies. • Prior smart research agendas focus on technical goals and traditional institutions. • We propose three shifts: political choice, diverse inclusion, connected citizens. • Questions support non-tokenistic inclusion of social aspects in technology projects.

While firms' investment in Industry 4.0 and adoption of circular economy practices are seen as indispensable to a sustainable economy, synergies from the interaction of these two received less systematic empirical treatment. These synergies are particularly important in Europe, given that both the digital and the green transitions are Europe's strategic political priorities, and the "twin" transitions are expected to reinforce each other. By investigating the link between Industry 4.0 technologies and circular economy practices for European SMEs, which have an important place in the European economy and are responsible for a significant amount of waste, this study aims to uncover the potential of digital transition in supporting green transition. Using the ReSOLVE framework as the conceptual background, this paper examines the effect of Industry 4.0 technologies on SMEs' circular economy applications among EU countries using firm-level data from SMEs, Start-ups, Scale-ups, and Entrepreneurship (Flash Eurobarometer 486) Survey in 2020. The results of econometric analyses provide evidence of a statistically significant positive effect of Industry 4.0 technologies on circular economy practices. These findings imply that a key policy priority should be to plan to spread Industry 4.0 components to improve and enhance SMEs' circular economy practices. Overall, the results indicate that Industry 4.0 technologies serve not only Europe's digital and industrial strategies but also its environmental strategies. [ABSTRACT FROM AUTHOR]

Two trends have shaped the European car market over the past decade: electrification and SUVisation. Recently, they have merged in a new product: the electric sport utility vehicle. This paper contrasts the view that regards this innovation as a technological solution to mitigate road transport emissions with a broader view that takes into account the battery requirement and profitability of such type of electric car. This broad view is formalised in a system dynamics model that captures the potential effects of supply side constraints. Four scenarios are simulated. The results show that the levels of CO 2 emissions of new cars are substantially reduced only in the one that assumes lower motorisation. Based on these simulations, the conclusion that the diffusion of electric sport utility vehicles does not necessarily contribute to mitigating car emissions in Europe is drawn. Less reliance on technology fixes, downsizing and reduced motorisation are identified as solutions worth investigating to meet ambitious climate goals. Further research on how vehicle manufacturers distribute batteries is needed. [Display omitted] • A novel system dynamics model of the new electric SUV market was developed. • Battery supply constraints considered as natural boundaries of road transport. • Four scenarios explored to simulate CO 2 emissions from cars in Europe. • Electric SUVs do not necessarily contribute to emissions mitigation. • Downsizing and lower motorisation are worth pursuing.

Extracting pieces of concrete from obsolete buildings and reusing them, as is, in new assemblies is today rarely considered a strategy for improving the sustainability of the construction sector. By delaying the crushing of concrete into aggregates and avoiding the need for fresh cement in new buildings, the circular strategy is however expected to reduce greenhouse gas emissions and threats to natural ecosystems. In reaction, the authors postulate that (1) built precedents of Piecewise Reuse of Extracted Concrete in new Structures (PRECS) have existed for several decades, (2) a large diversity of proven implementation techniques is readily available but knowledge is fragmented, (3) barriers to a broader adoption can be inferred from the existing documentation and are largely transitional. To support these postulates, this study first builds an original collection of 77 PRECS projects designed between 1967 and 2022 in Europe and the U.S.A. Next, a diachronic analysis determines seven historical trends and three periods since 1967, shedding new light on the development of PRECS and its design possibilities. Supporting and limiting forces for a broader adoption of PRECS are then identified through a synchronic analysis. Recommendations for future research directions are also given. In conclusion, this paper demonstrates that the reuse of concrete components is a practice with already a long history and several successful operations in terms of environmental impact and cost, which hence supports the potential of PRECS to become a more widespread strategy of cleaner construction. • Reusing concrete pieces in new structures is a rarely considered sustainability strategy. • An original database of 77 concrete reuse case studies is built and analyzed. • Ecological benefits are confirmed for a wide range of built cases. • Circumstances leading to economic benefits are identified. • Industrial and scientific developments can accelerate the strategy implementation.

This paper examines the risk transmissions across the green economy indices of three major regions which include US, Europe and Asia. The econometric analyses are conducted using DCC-GARCH and TVP-VAR connectedness approach to evaluate potential spillover effects within the context of oil and gold. Results indicate that green economy indices of US-Europe exhibit the greatest time-varying correlations among the three pairs during much of 2010–2022 consistent with that of the general equity market. However, co-movements during the COVID-19 pandemic period seem to display a change in pattern for green economy indices. The strength of the co-movements between the US and Europe displayed a declining trend, while that between US and Asia was strengthened, suggesting greater interdependence between these two markets. TVP-VAR connectedness analysis revealed that US and Europe dominate the transmission of the shocks across the years in the green economy, similar to that of the equity markets. However, during the pandemic a pronounced shift occurred in green economies when considering the risk transmissions within the context of commodities: oil and gold. While Asian green economy index was persistently a receiver of risk transmission from oil unlike the other two regions, since pandemic, oil displayed an asymmetric effect and has become the net transmitter of risk in negative returns of the green economies of US and Europe. This may reflect the diversion in environmental policies of the two regions in the recent past, and point to the dominance of energy sector in the green economy. These findings have substantial implications for the development of green economy policies and from an investment perspective. [ABSTRACT FROM AUTHOR]

This paper aims to explore whether the female share on the boards of directors of companies influences CO2 emissions in both developed and emerging markets. Furthermore, the influence of cultural diversity on the board of directors on CO2 emissions is analysed. A sample of companies belonging to the MSCI and MSCI Emerging Market indices in Europe over ten years (2010–2019) was analysed using regression models with panel data. The results demonstrate that in both developed and developing markets, the ratio of women to men on the board of directors is inversely related to the company's CO2 emissions, which support legitimacy theory in two aspects: it fulfils the right to equality and non-discrimination for women, and it also reduces CO2 emissions. In general, cultural diversity had a negative influence on CO2 emissions. This research is relevant for policymakers and managers seeking to improve sustainability and equality policies in companies. If gender equality in corporate monitoring roles is environmentally beneficial for the planet, legislators will support quota policies. In addition, shareholders will have an incentive to implement gender equality policies, as they will legitimise the company in the eyes of society, which has economic benefits. On a practical level, this work will contribute to achieving gender equality in corporate governance and improve the understanding of factors influencing CO2 emissions to the environment. This study contributes to previous research since it is the first time that developed and emerging countries have been analysed with the same methodology in relation to gender and CO2 emissions. Moreover, this research differentiates between emission-sensitive and insensitive sectors, and it is the only study to carry out a sector-by-sector and a country-by-country analysis. Furthermore, cultural diversity on corporate boards has been scarcely studied so far in relation to CO2 emissions. • Gender diversity on boards of directors is associated to lower CO2 emissions. • Cultural diversity on boards of directors is positively related to CO2 emissions. • Improving gender balances on board of directors is a sustainable strategy. • Gender equality policies on corporate boards favor climate action and life on land. • Legal gender quotas on corporate boards contribute to good health and well-being.

With the move to a hydrogen-based primary steel production envisioned for the near future in Europe, existing regional industrial clusters loose major assets. Such a restructuring of industries may result in a new geographical distribution of the steel industry and also to another quality of vertical integration at sites. Both implications could turn out as drivers or barriers to invest in new technologies and are thus important in respect to vertical integration of sites and to regional policy. This paper describes an approach to model production stock invest for the steel industries in North-Western Europe. Current spatial structures are reproduced with capacity, technical and energy efficiency data on the level of single facilities like blast furnaces. With the model developed both investments in specific technologies and at specific production sites can be modelled. The model is used to simulate different possible future scenarios. The case with a clear move to hydrogen-based production is compared to a reference scenario without technological shift. The scenarios show that existing trends like movement of production to the coast may be accelerated by the new technology but that sites in the hinterland can also adapt to a hydrogen economy. Possible effects of business cycles or a circular economy on regional value chains are explored with a Monte-Carlo analysis. • Differing starting positions for steel sites to adopt hydrogen based steel making. • Model to identify competitiveness of steel sites in an evolving hydrogen economy. • Scenarios on spatial structure of steel industry in various steel market developments. • Not only coastal but also inland sites are able to adopt green steel technologies. • Input to the recent discussion to build hydrogen pipelines for the steel industry.

The building sector brings the main responsibility for energy consumption and GHG emissions in European countries. Although many policies have been placed across the EU to increase building energy performance, the current home energy renovation rate remains too low to achieve the EU's decarbonization targets. The One-stop-shop (OSS) concept is emerging as an innovative solution to boost energy home renovation and overcome barriers hindering the renovation process. The OSS is a physical or virtual place where customers obtain multiple products and services at one single point. Through literature review and desk research, 29 OSS initiatives have been analysed in the EU looking at their Business Models (BM). The paper aims to categorize and compare OSS BMs to increase knowledge about OSS functioning and capacity to affect and bring innovation to home renovation process. Three BM archetypes emerge, Facilitation model, Coordination model, and Development model. Within OSS archetypes, seven BM sub-categories have been identified and described. To provide insights for implementing new businesses and revitalizing the home renovation sector, OSS archetypes and sub-categories are compared and assessed, first considering four analytical frameworks and then looking at their capacity to overcome home renovation barriers. Results can be useful to foster energy home renovation by supporting the development of effective and targeted OSS initiatives across the EU. • One-Stop-Shops play a key role in fostering the energy home renovation process. • Several One-Stop-Shops exist in Europe and strongly differ in terms of business model. • Three One-Stop-Shop archetypes and seven sub-categories emerged from the analysis. • 5 factors shape the models: value proposition, services, revenue, partnership, social value. • One-Stop-Shop models lead to different impacts and benefits on the renovation process.
