Since its establishment more than 34 years ago, the Global Environment Facility (GEF) has played a critical role in addressing global environmental challenges. Co-founded by the World Bank Group, the United Nations Environment Programme (UNEP), and the United Nations Development Programme (UNDP), the GEF has supported developing countries in adopting integrated approaches to sustainable development.
In collaboration with the GEF, the World Bank Group has facilitated transformative investments and financing strategies across sectors such as renewable energy, energy efficiency, sustainable transportation, biodiversity conservation, waste management, sustainable land management, and the blue economy. GEF financing enables the Bank to offer blended and flexible funding options that often act as a catalyst for larger projects by attracting private investment and mitigating risks. This has supported the piloting of innovative solutions and the mobilization of private capital for environmental and climate-related efforts.
GEF financing also contributes to clean, resilient, and low-carbon growth, while generating co-benefits such as employment and livelihood improvement. The partnership between the World Bank and the GEF has alleviated economic pressures and strengthened resilience in vulnerable communities and ecosystems worldwide.
Beginning with GEF-6, the Facility has emphasized integrated programming designed to drive systemic transformations in global economic sectors. As a lead agency for Integrated Programs, the World Bank has expanded its work on nature-related issues by building strategic partnerships, enhancing policy engagement, involving key economic stakeholders, and mobilizing financial resources to scale environmental impact.
Since its inception, the GEF has approved over 870 projects in 146 countries, allocating nearly US$5.6 billion in funding. These investments have attracted approximately US$44 billion in co-financing from other sources, achieving a leveraging ratio of 1:8. The GEF’s financial support has helped countries improve natural resource management and transition toward environmentally sustainable economic growth.
GEF-supported initiatives have led to groundbreaking investments in areas such as renewable energy and sustainable transport, including foundational support for China’s renewable energy expansion. The GEF has also facilitated the creation of new financial mechanisms for biodiversity protection and sustainable land use, such as the Sahel and West Africa Program, which mobilized more than US$1 billion to enhance food security and climate resilience across 12 countries, benefiting over 19 million people. The International Finance Corporation (IFC) has used GEF grants to blend with commercial capital, enabling the development of private markets with strong developmental impacts.
GEF funding has also supported innovation in conservation finance. The Wildlife Conservation Bond represents a pioneering, outcome-based financial instrument that channels investment into conservation projects, with success measured by growth in black rhino populations. If conservation targets are achieved, investors receive a success payment funded by a GEF-backed performance grant, along with the return of their initial capital.
This approach introduces a novel model of conservation financing that transfers risk to capital market investors while enabling donors to fund tangible conservation outcomes. The proceeds from the bond allow South Africa to further strengthen its long-standing and effective rhino conservation efforts.
