Green finance and sustainable investment strategies have become central to global efforts in addressing climate change and fostering inclusive economic growth. These mechanisms aim to direct capital flows toward environmentally sustainable, socially inclusive, and economically viable ventures. This paper explores the concept of green finance and evaluates various financial instruments such as green bonds, sustainability-linked loans (SLLs), carbon markets, and ESG (Environmental, Social, and Governance) investment models. It also assesses their role in promoting sustainable development through performance indicators such as return on investment (ROI), risk mitigation, long-term value creation, and investor sentiment. The research adopts a secondary data methodology, drawing insights from academic literature, government policies, financial databases, and international case studies. A comparative analysis of global best practices in the European Union, United States, and China highlights effective regulatory frameworks, market innovations, and policy-driven initiatives that can be adapted to strengthen India’s green finance ecosystem. Findings reveal that green financial instruments offer competitive returns and enhance risk resilience while promoting transparency and accountability. However, challenges such as inconsistent ESG disclosure, lack of a unified taxonomy, limited retail awareness, and underdeveloped carbon market infrastructure continue to hinder progress. This paper concludes with strategic policy recommendations, including the development of a national green taxonomy, mandating ESG disclosures, incentivizing green investments, and enhancing access to green finance for SMEs. Overall, green finance presents a transformative opportunity to align capital markets with sustainable development goals and accelerate India's transition to a low-carbon, climate-resilient economy
