Adaptation Finance: 10 Key Questions, Answered

This fact sheet from the World Resources Institute explains the definition, scale, and challenges of adaptation finance, which funds projects to build resilience against climate change impacts. It highlights a significant funding gap in developing countries and the difficulties in tracking these investments compared to climate mitigation.

• Adaptation finance is defined as funding explicitly intended to enhance resilience to actual or expected climate risks, such as strengthening infrastructure, developing drought-tolerant crops, and creating social safety nets. It differs from general development finance in that it must be deliberately designed with climate impacts and the needs of vulnerable populations in mind.
• There is a substantial gap between the adaptation finance needed by developing countries and the amount available. The UNEP Adaptation Finance GAP Report estimates annual needs between $215 billion and $387 billion by 2030, while the estimated annual gap is between $187 billion and $359 billion.
• Adaptation finance is significantly underfunded compared to climate mitigation, representing less than 10% of global climate investments. Mitigation attracts more funding because it often provides more immediate and certain financial returns, such as through solar panels or electric vehicles, whereas adaptation focuses on long-term resilience to future events.
• Finance is not reaching the most vulnerable populations; low-income countries received less than 10% of all climate finance provided and mobilized by developed countries from 2016 to 2022. Barriers to access include a lack of institutional capacity to structure bankable initiatives and high costs of capital due to political and currency risks.
• Tracking adaptation finance is difficult because it is highly context-specific and lacks centralized accounting for private sector investments. While the OECD DAC Rio Markers and MDB Joint Methodology provide guidance, many countries use modified national approaches, making data difficult to compare.
• The vast majority of adaptation finance is public; approximately 90% of tracked finance comes from public actors. Private investment is limited by perceived risks in vulnerable areas, uncertainty regarding adaptation options, and a lack of clear financial returns.
• Under the New Collective Quantified Goal (NCQG) agreed at COP29, parties committed to delivering $300 billion—with efforts to reach $1.3 trillion—for climate action in developing countries by 2035, with a focus on balancing mitigation and adaptation and increasing grant-based, concessional finance.
• Adaptation finance is distinct from 'loss and damage' finance: adaptation helps communities prepare for and reduce potential impacts, while loss and damage finance pays for losses that occur despite resilience investments.
