The smart sustainable city (SSC) is a concept created in response to problems and challenges arising from rapid urbanization. This is a relatively new term that is developing dynamically, which is confirmed by the growing number of publications over recent years. For this reason, this article presented an up-to-date comprehensive bibliometric analysis to describe and assess the scientific landscape of smart and sustainable cities literature. The analysis was based on two bibliographic sources—the Web of Science Core Collection and the Scopus database. It covers publications on the SSC, as well as documents describing the smart city (SC) and the sustainable city (SuC) concepts separately. VOSviewer and Biblioshiny were selected as software tools for the bibliometric analysis. Based on the descriptive bibliometric analysis, quantity and quality indicators were determined separately for the SC, SuC, and SSC concepts, while the network analysis mapped and covered the level of multi-faceted scientific cooperation in the field of the SSC research. The analysis results were intended to familiarize scholars and practitioners with the most prolific authors, sources, institutions, and countries in the analyzed scientific field, to identify the most influential research channels and impact from authors, sources, countries, and research topics, to determine major clusters of the SSC research and also to provide valuable information for further investigation.

Nowadays, scholars exploring the relationship between proactive environmental strategy and firm competitiveness do not focus on the question of whether it pays to be green but rather investigate when, for whom or how it does so. This paper analyzes the links between proactive environmental strategy, technological eco-innovation and firm performance. In particular, it examines the influence of proactive environmental strategy on firm performance and explores this relationship through technological eco-innovation. A research model has been developed and tested using a sample of 292 firms operating in Poland. In order to test the proposed research model and hypotheses, structural equation modeling using partial least squares has been employed. The findings do not confirm that proactive environmental strategy directly affects firm performance. However, the results show the significant mediating role of technological eco-innovation in this relationship. Since the technological eco-innovation reduces environmental impact and improves business performance, this research proves that it simultaneously contributes to environmental and economic pillars of sustainable development.

The achievement of climate neutrality and eco-economic decoupling requires explicit measures to reduce greenhouse gases (GHG) emissions and to implement circular economy (CE) principles in practice. The energy sector is of particular importance in meeting these challenges because it exerts a substantial environmental impact. Therefore, it is extremely important to determine how essential GHG and CE issues are for companies operating in the energy sector. This can be reflected in corporate strategies, but it can also be disclosed to the public in sustainability reports. For this reason, this article presents a comprehensive analysis of sustainability reports based on the latest GRI Standards published by companies representing the energy sector in the European Union to determine the existence, quality, and specificity of reporting GHG and CE issues. The research results demonstrate that sustainability reports from the energy sector companies tend to focus more on GHG issues. They rarely point to actions related to CE, including actions enabling a reduction in GHG emissions, as those with high priority. In addition, declarations from the analyzed companies regarding intentions related to GHG and CE issues at the strategic level find a rather poor reflection in the description of specific actions in this area or in demonstrating appropriate indicators at the operational level. Considering the indicators included in the reports, the analyzed companies insufficiently describe the methods they use to gather, compile, and analyze information on the effectiveness of actions taken to address GHG and CE issues. As for the identification of potential determinants of the quality of reporting GHG and CE issues, the research results indicate that it is mostly influenced by external assurance and the report option. Sustainability reports submitted for external assurance and reports with the comprehensive option are significantly more developed than other types of reports. However, the clarity of reports with the core option is higher compared to the comprehensive group. In addition, it was indicated that the clarity of stand-alone reports is higher compared to other types of reports.

Although previous research has suggested that interorganizational cooperation and knowledge sharing may affect technological eco-innovation or proactive environmental strategy, there is little understanding of the interconnectedness of these variables. This paper investigates the links between interorganizational cooperation, knowledge sharing, proactive environmental strategy, and technological eco-innovation. In particular, it examines the infl uence of interorganizational cooperation and knowledge sharing on technological eco-innovation and explores these relationships through proactive environmental strategy. A research model has been developed and tested on a sample of 292 fi rms operating in Poland. In order to test the proposed research model and hypotheses, structural equation modeling using partial least squares has been applied. The fi ndings indicate direct effects of interorganizational cooperation and knowledge sharing on proactive environmental strategy. However, the obtained results do not prove that interorganizational cooperation directly affects technological eco-innovation. Nevertheless, the study has shown the signifi cant mediating role of proactive environmental strategy in relationships between interorganizational cooperation, knowledge sharing, and technological eco-innovation. Since proactive environmental strategy powerfully fuels technological eco-innovation and signifi cantly mediates links between interorganizational cooperation, knowledge sharing, and technological eco-innovation, this research proves that it constitutes a unique organizational capability that may improve transformation of knowledge into better environmental and economic performance.

Due to the growing academic interest in social innovation, there is a need for a comprehensive bibliometric analysis of the structure and evolution of this research field. So far, there have been very few in-depth studies in this area. In addition, the number of publications in this domain grows dynamically year by year. For this reason, it was assumed that the existing research needs expansion and updating. Therefore, this study presents a comprehensive bibliometric analysis aiming to identify research patterns and trends in the scientific literature on social innovation. Descriptive and performance analyses as well as research field mapping based on network analyses were performed. The most productive authors, sources, academic organizations, and countries in the social innovation literature were indicated. Moreover, the most influential authors and publications in the analyzed research field were determined. Furthermore, the evolution of social innovation research and the scientific collaboration in this area were shown and characterized. The analysis results were intended to show academics and practitioners an up-to-date, comprehensive picture of the multidisciplinary and multifaceted phenomenon of the research on social innovation.

This paper presents a systematic literature review (SLR) of research on strategic positioning of companies and the measurement of greenwashing in sustainability reporting. Its main aim is to synthesize and organize the existing literature, identify key research gaps, and outline directions for future studies. Drawing on a rigorous content analysis of 88 studies, we delineate strategic typologies of greenwashing in sustainability reporting and examine content-analysis-based measurement approaches used to detect it. Our SLR shows that most strategic typologies draw on theories such as legitimacy theory, impression management theory, signaling theory, and stakeholder theory. Several studies adopt a four-quadrant matrix with varying conceptual dimensions, while others classify strategic responses to institutional pressures along a passive–active continuum. However, the evidence suggests that to assume that companies uniformly pursue sustainability reporting strategies is a major oversimplification. The findings also indicate that the literature proposes a variety of innovative, content-analysis-based approaches aimed at capturing divergences between communicative claims and organizational realities—most notably, discrepancies between disclosure and measurable performance, and between symbolic and substantive sustainability actions, as well as the identification of selective or manipulative communication practices that may signal greenwashing. Analytical techniques commonly focus on linguistic and visual cues in sustainability reports, including tone (sentiment and narrative framing), readability (both traditional readability indices and machine learning–based textual complexity measures), and visual content (selective emphasis, imagery framing, and graphic distortions). We also synthesize studies that document empirically verified instances of greenwashing and contrast them with research that, in our view, relies on overly simplified or untested assumptions. Based on this SLR, we identify central theoretical and methodological priorities for advancing the study of greenwashing in sustainability reporting and propose a research agenda to guide future research.
