Circular Economy Narratives as Corporate Social Responsibility Strategies: Organisational Identity and Legitimacy Natália Teixeira Corporate Social Responsibility and Environmental Management, 2026 Organisations increasingly frame the circular economy as part of their corporate social responsibility (CSR) strategies, yet the meaning of circularity remains fluid and contested. While prior research has emphasised the technical and operational dimensions of circular economy practices, less is known about how organisations use circularity narratives to manage identity and legitimacy in sustainability transitions. This article develops a conceptual framework that theorises circular economy narratives as strategic CSR resources and explains how organisations mobilise authentic, strategic, and defensive narratives in response to stakeholder expectations and institutional pressures. Drawing on illustrative secondary material from the energy, fashion, and packaging sectors, the framework shows how different narrative approaches are associated with distinct legitimacy outcomes and greenwashing risks. By linking circular economy narratives to CSR strategy, organisational identity, and legitimacy management, this article contributes to research on CSR and environmental management and provides a foundation for future empirical research on CSR communication, legitimacy management, and environmental governance.
Beyond ESG Disclosure: Circular Economy Practices and Corporate Financial Performance Across Global Sectors Natália Teixeira Corporate Social Responsibility and Environmental Management, 2026 The growing prominence of environmental, social and governance (ESG) metrics has reshaped how corporate sustainability is assessed, yet these indicators often prioritise disclosure over operational transformation. This study examines whether circular economy practices, conceptualised as an operational dimension of corporate social responsibility, are associated with corporate financial performance beyond conventional ESG scores. Using a balanced panel of leading global firms across four sectors over the period 2015–2024, the analysis explores the relationship between the degree of circular economy adoption, market valuation and profitability indicators. The results indicate that firms with higher levels of circular economy adoption tend to have higher market capitalisation and superior financial returns (measured by ROA and ROE), while ESG scores display a weaker and, in some cases, negative association with valuation. These findings suggest that circular economy practices capture dimensions of sustainability performance not fully reflected in ESG ratings. By empirically distinguishing between sustainability disclosure and operational circularity, this study contributes to the corporate social responsibility and sustainability strategy literature and offers practical insights for managers, investors, and policymakers seeking to align sustainability initiatives with long‐term value creation.
Green digital finance and new quality productive forces: bridging technological innovation and sustainable productivity Natália Teixeira China Finance Review International, 2026 Purpose This study critically reviews the emerging literature on green digital finance, focusing on the interplay between digital technologies and sustainable financial transformation. This review examines four key domains (blockchain, artificial intelligence, big data and digital platforms) and analyses their potential contributions to green finance as well as associated risks. A conceptual framework is proposed to illustrate how digital innovations, supported by appropriate institutional contexts, can foster new quality productive forces. The study identifies major research gaps, particularly the lack of empirical assessments, the need for harmonised governance mechanisms and the limited engagement with behavioural dynamics. Policy and managerial implications are outlined, with strategic recommendations for regulators, financial institutions, platform providers and development agencies. The paper concludes by highlighting directions for future interdisciplinary research and practical frameworks to align green finance with technological transformation and sustainable productivity. Additionally, the work contributes to the ongoing debate on the emergence of new quality productive forces, analysing how green digital finance can act as a catalyst for sustainable economic transformation through technological innovation and institutional realignment. Design/methodology/approach The paper adopts a critical literature review methodology, systematically analysing peer-reviewed studies and policy documents on green digital finance across four technological domains. A conceptual framework is developed to structure the relationship between technological tools, institutional enablers and productive transformation. The review is complemented by a structured research agenda and a matrix of stakeholder-specific implications. Findings The review identifies four key technological drivers of green digital finance and highlights both their transformative potential and systemic risks. It finds that blockchain and AI can support traceability and automation, but face governance and bias concerns. Big data and platforms offer behavioural and analytical advantages, yet pose challenges in terms of privacy, data quality and accountability. The study concludes that green digital finance can catalyse new productive forces if supported by institutional innovation, inclusive design and standardised evaluation metrics. Originality/value This paper is among the first to systematically link green digital finance to the formation of new quality productive forces, providing both a conceptual framework and a policy-oriented synthesis of technological developments. Unlike prior reviews, it integrates critical reflections on governance, behavioural factors and empirical gaps, offering a structured research and policy agenda with relevance for China and other emerging economies.
Circular economy perspectives: challenges, innovations, and sustainable futures Natália Teixeira Discover Sustainability, 2025 Purpose This study presents a systematic review of the literature on Circular Economy (CE), examining its theoretical foundations, governance mechanisms, enabling technologies, and implementation challenges in various contexts. Design/methodology/approach Following the PRISMA guidelines, the review covers peer-reviewed articles published between 2017 and 2025. The Scopus and Web of Science databases were searched using a defined chain strategy. After applying the inclusion and exclusion criteria, 111 articles were selected and analysed thematically. Results The results highlight the fragmented and evolving nature of the debate on CE. Four main dimensions emerged: (i) conceptual foundations, with competing paradigms between economic and ecological schools; (ii) policies and governance, where regulatory gaps and incompatibilities between scales remain fundamental constraints; (iii) technological enablers, particularly digital tools and renewable solutions, with varying levels of maturity; and (iv) barriers to implementation, including financial, institutional, and cultural constraints. The literature reveals regional asymmetries, sectoral fragmentation, and limited integration of CE into broader sustainability strategies. Originality This study contributes by offering a structured synthesis of the field of CE, identifying dominant patterns and critical gaps. It also proposes a future research agenda focused on governance innovation, technological integration, and coordination between scales to promote circular transitions.
Green Innovation and National Competitiveness: Rethinking Economic Resilience in the Sustainability Transition Natália Teixeira Sustainability Switzerland, 2025 With environmental and economic disruptions occurring faster than ever before, the link between green innovation and national competitiveness deserves further analysis. This article investigates how sustainability-oriented strategies (particularly investments in research and development (R&D), renewable energy, and innovation capacity) affect the performance of environmental goods exports and national economic resilience. An exploratory cross-sectional analysis is conducted using multiple linear regression models applied to a sample of 14 countries, including the seven most sustainability-oriented economies and seven countries whose economic growth relies predominantly on fossil fuels. The results suggest a strong positive relationship between R&D expenditure and green trade competitiveness, while renewable energy consumption indicators produce mixed or even negative short-term effects. Adjusted net savings emerge as a robust indicator of both growth and competitiveness. However, no significant associations were found between renewable energy indicators and economic resilience, highlighting transitional trade-offs and institutional barriers inherent in ecological transformation. The study contributes to the growing literature on green transitions by combining macroeconomic indicators of innovation and sustainability with export performance. Policy implications include aligning innovation strategies with trade objectives, improving the measurement of green competitiveness, and supporting institutional preparedness for the transition.
Macroeconomic Determinants of Subjective Well-Being in Portugal: Pathways to Social Sustainability Natália Teixeira, Leandro Pereira, Rui Vinhas da Silva Sustainability Switzerland, 2025 The measurement of national well-being has become central to both academic and policy debates, particularly within the framework of sustainable development. In this context, this study investigates the relationship between macroeconomic conditions and subjective well-being in Portugal. Using annual data from 2004 to 2022, we explore the effects of GDP per capita, unemployment, and inflation on the Global Well-Being Index (GWBI). Employing ordinary least squares (OLS) regression, the results indicate a significant positive relationship between GDP per capita and subjective well-being, while inflation is negatively associated. Contrary to expectations, the unemployment rate showed a positive and significant association with the GWBI. This counterintuitive result may reflect institutional buffering effects, such as social safety nets, strong family structures, or lagged responses in perceptions of well-being. Similar patterns were observed in other southern European countries with strong informal social support systems. These findings contribute to a deeper understanding of how economic indicators relate to perceived well-being, particularly in the context of a southern European country. The study offers relevant insights for public policy, including the alignment of macroeconomic management with the Sustainable Development Goals (SDGs), especially SDG 3 (Good Health and Well-being) and SDG 8 (Decent Work and Economic Growth).
Developing Theoretical and Methodological Provisions for Improving the Mechanism of Labour Efficiency Tetiana Kornieieva, Miguel Varela, Ana Lúcia Luís, Natália Teixeira Administrative Sciences, 2024 The article presents a theoretical generalisation and solution of a current scientific and applied problem which develops theoretical principles, methodological approaches and scientific and practical recommendations for improving the mechanism of labour efficiency management in terms of innovation-oriented development of enterprises. It is substantiated that in the conditions of innovation-oriented development of ecosystems, including enterprises, the disclosure of the essence of labour efficiency requires introduction of a dual quantitative–qualitative approach: on the one hand, labour efficiency reflects the ratio of the manufactured products (tangible and intangible benefits) and corresponding living labour costs (quantitative aspect) and, on the other hand, it is the result of using productive abilities of people, characterised by manufactured products of a particular consumer quality with the creation of added value (qualitative aspect). Conceptual bases of improvement of the mechanism of labour efficiency management at enterprises were developed. They are based on certain tasks, functions, principles, methods of labour efficiency management and the formed system of factors of influence and the revealed factors and reserves of an increase in labour efficiency. They presuppose development and realisation of the corresponding programme, which aims to: optimise total labour costs; improve quality of products at a constant mass and satisfaction with the work process of all its participants; ensure positive changes in material well-being and quality of life on the basis of the formation of modern innovation infrastructure of the enterprise.
