Making blended finance work for nature-based solutions

The document argues that the global biodiversity finance gap—estimated at an annual need of USD 536 billion by 2050—cannot be closed by grants alone. It proposes a blended finance approach that integrates information, regulatory, economic, institutional, and financial instruments to de-risk investments and catalyze private capital. Using the Green Climate Fund's (GCF) portfolio as a basis, the paper demonstrates how combining instruments (e.g., pairing carbon credits with parametric insurance), sequencing them along a maturity-concessionality gradient (e.g., the Amazon Bioeconomy Fund), and establishing long-term partnerships (e.g., Project Finance for Permanence) can create sustainable financial models for nature-based solutions.

• There is a significant global financing gap for nature; by 2050, annual investment needs for nature are projected to reach USD 536 billion, which is more than four times the current annual flows of USD 133 billion.
• Nature-negative expenditures currently far exceed investments in nature-based solutions, with government spending on environmentally harmful subsidies for fisheries, agriculture, and fossil fuels estimated between USD 500 billion and USD 1.8 trillion per year.
• The Green Climate Fund (GCF) has integrated nature-based solutions into a substantial portion of its work; as of January 2023, 45 per cent of its portfolio contributes to these solutions, with 114 approved projects focusing at least partly on nature conservation, sustainable management, or restoration.
• The document categorizes instruments to catalyze finance into five types: information instruments (e.g., risk disclosures), control and regulatory instruments (e.g., protected areas), economic and market instruments (e.g., biodiversity-positive carbon credits), institutional instruments (e.g., green banks), and financial instruments (e.g., equity and guarantees).
• Blended finance is most effective when instruments are combined to offset individual weaknesses; for example, combining carbon credits with upfront grants, concessional debt, or parametric insurance can address price volatility and the risk of asset destruction.
• Financial instruments should be sequenced along a "maturity-concessionality" gradient, where early-stage businesses rely on highly concessional finance like grants and gradually transition to commercial loans and capital markets as they mature.
• The Amazon Bioeconomy Fund, supported by GCF with USD 279 million, exemplifies sequencing by providing a grant window for small/indigenous businesses, equity for early-stage innovative companies, and sovereign/corporate loans for mature businesses.
• Project Finance for Permanence (PFP) is a partnership approach used to secure long-term funding for conservation goals in perpetuity, as seen in the Heritage Colombia (HECO) programme, which combines GCF grants (USD 43 million) with Colombian government funds (USD 69 million).
• Debt-for-nature swaps, such as the blue bond agreement in Belize, allow countries to reduce external debt while generating funds for marine conservation; in Belize's case, this is expected to generate USD 180 million to increase marine protection from 16 per cent to 30 per cent by 2026.
