The shift from linear to circular production and consumption models is becoming a key policy in resource efficiency, emission reduction and supply chain resilience while the integration of disclosure frameworks (ISSB/IFRS, ESRS/ CSRD) and sustainable finance (SFDR, Taxonomy, EuGBS) makes ESG indicators the “currency” of information for capital markets. The objective of this thesis is to provide an answer to the following research question: In which ways and to what extent do Circular Economy practices improve ESG performance and through them affect the competitiveness of businesses and the attraction of sustainable investments? More specifically, it maps the circular interventions (life extension, reuse/remanufacture, secondary content, resource efficiency) with the ESRS E5 metrics and related indicators (MCI, Circulytics), through which mechanisms of circularity feed operational efficiency, product differentiation/branding and servitization, and analyzes the channels for transferring this performance to capital markets (Taxonomy alignment, articles 8/9 SFDR, green bonds/EuGBS) under conditions of materiality per sector and measurable in a reliable way. The synthetic review of institutional and academic sources demonstrates that disciplined circularity targeting is associated with reduced material/energy costs, lower equity costs and enhanced access to sustainable financing products, while the spatial distribution of flows (particularly in the Eurozone) highlights the role of institutional credibility, transparency and a pool of eligible projects. Meanwhile, barriers for SMEs (CAPEX, data/assurance, skills) and risks of misinformation are recognized, requiring digital product passports, public procurement with life-cycle criteria, financial instruments connected to circularity KPIs and interoperability of standards. In general, the circular economy appears as a measurable driver of ESG, competitiveness and investment attractiveness
