This chapter explores the integration of Environmental, Social, and Governance (ESG) principles and the Sustainable Development Goals (SDGs) into circular economy financing, highlighting their transformative impact on financial decision-making and sustainability outcomes. It examines how ESG criteria are reshaping credit assessments, investment allocation, and loan structuring, while the SDGs provide a unifying framework that ensures financing contributes directly to environmental protection, social equity, and economic resilience. The chapter underscores the benefits of ESG integration, including reduced risk exposure, enhanced access to capital, and improved stakeholder trust, while also addressing challenges such as inconsistent reporting standards, risks of greenwashing, and limited capacity among small and medium-sized enterprises (SMEs). Policy recommendations emphasize harmonizing disclosure frameworks, promoting blended finance, and building capacity to democratize access to sustainable finance. The study concludes that embedding ESG and SDG considerations in everyday financial practices is vital for accelerating a just and inclusive transition to a circular economy.
