Key Barriers to Advancing Climate Change Adaptation through Nature-based Solutions: Challenges in Accessing Finance

The document identifies a significant funding gap for nature-based solutions (NbS), noting that current annual investments of USD 200 billion must increase to USD 542 billion by 2030 to meet global goals. Key barriers include a heavy reliance on public finance (over 80%), a lack of bankable models for ecosystem services, and a dearth of business cases for the private sector. To address these, the brief suggests blended finance to mitigate risk, innovative instruments like green and blue bonds, and the use of natural capital accounting to assign economic value to nature's benefits.

• To meet global climate adaptation and biodiversity ambitions, such as those in the Paris Agreement and the Kunming-Montreal Global Biodiversity Framework, an investment of approximately USD 11 trillion is needed by 2050. This requires annual investment in NbS to rise from the current USD 200 billion to USD 542 billion by 2030.
• NbS financing is currently dominated by the public sector, which provides more than 80% of investment. Private sector engagement is limited by the perception that NbS are high-risk and a lack of incentives beyond improving supply chain resilience.
• A primary obstacle to private investment is the lack of 'bankable' models and a compelling business case. NbS are frequently viewed as conservation projects rather than sustainable development investments, and there are few established methods to determine the financial value of ecosystem services.
• The lack of robust data and a chronic shortage of useful metrics hinder the ability of investors to evaluate and compare project outcomes. This data deficiency is exacerbated by insufficient funding for practitioners to monitor results, which in turn weakens the investment case for NbS.
• Blended finance models, which combine public and philanthropic development funding with private finance, are proposed to mitigate private sector risk by providing a financial cushion against uncertainty.
• The document identifies several innovative financing instruments and valuation methods to scale NbS, including green and blue bonds, debt for nature swaps, budget tagging, natural capital accounting, and ecosystem service valuation.
