The Nexus Between Green Finance, Biodiversity Conservation, and Sustainable Development: A Review

Abstract

The accelerating loss of biodiversity has become one of the most critical sustainability challenges of the twenty-first century, with profound ecological, social, and economic implications. Ecosystem degradation threatens essential services such as food security, water availability, climate regulation, and overall economic stability, thereby undermining the foundation of sustainable development. Despite increasing global awareness, conventional public financing mechanisms remain insufficient to address the scale and urgency of biodiversity loss, highlighting the need for alternative and complementary funding approaches. In this context, green finance has emerged as a promising mechanism for mobilizing private capital and integrating environmental considerations into financial decision-making. This paper, titled “The Nexus Between Green Finance, Biodiversity Conservation, and Sustainable Development: A Review,” adopts a narrative synthesis approach to examine the evolving relationship between financial systems and biodiversity conservation. Drawing on peer-reviewed literature, policy reports, and global sustainability frameworks, the study provides a comprehensive assessment of how green finance instruments are being expanded beyond their traditional climate focus to incorporate biodiversity-related objectives. The review explores key financial instruments, including green bonds, blended finance, and innovative nature-based mechanisms, and evaluates their potential to support ecosystem conservation, restoration, and sustainable resource management. It further highlights critical challenges, such as the absence of standardized biodiversity metrics, valuation difficulties, weak governance structures, and the risk of greenwashing, which continue to limit the effectiveness of biodiversity finance. The findings underscore the importance of understanding the nexus between green finance, biodiversity conservation, and sustainable development, emphasizing the need for stronger institutional frameworks, improved data systems, and policy alignment. The paper concludes by identifying key research and policy directions, including the development of robust biodiversity indicators and enhanced collaboration among stakeholders. Ultimately, advancing biodiversity-inclusive green finance is essential for achieving long-term ecological sustainability and resilient economic development.
