Abstract—Abstract: The global climate crisis demands urgent and transformative financial mechanisms to support mitigation and adaptation efforts. Traditional climate finance models face significant challenges, including inefficiency, limited transparency, and inequitable access, particularly for marginalized communities. Decentralized Finance (DeFi), based on blockchain technology, offers a promising solution by enhancing transparency, utilizing smart contracts, and enabling decentralized governance. This study explores the role of DeFi in revolutionizing climate finance through a mixed-methods approach. It combines quantitative analysis of blockchain-based climate finance transactions with qualitative insights from industry experts, policymakers, and developers. The findings reveal that DeFi can reduce transaction costs, improve transparency, and democratize access to climate funds, with case studies such as KlimaDAO and the Toucan Protocol illustrating its potential in carbon credit systems and renewable energy projects. However, challenges such as regulatory uncertainty, technical vulnerabilities, and scalability issues persist. This research contributes to the growing discourse on integrating DeFi into climate finance by proposing a conceptual framework for its application and outlining future research directions. The results have significant implications for academics, practitioners, and policymakers striving to create effective, scalable solutions for financing climate action.

Keywords—blockchain, carbon credits, climate finance, Decentralized Finance (DeFi), sustainability
