Solution Structure long-term Resilience Purchase Agreements (RPAs) between nature restoration projects and corporate buyers to generate stable contracted cashflows from ecosystem services, making catchment-scale nature restoration investable for institutional asset owners such as pension funds. Key challenge Degraded natural landscapes (rivers, wetlands, peatlands) increase flood and drought risk for businesses and communities, but nature restoration has lacked the contracted revenue streams and institutional-grade structures needed to attract private capital at scale. Context UK flooding, drought, and degraded water quality compound into a significant annual economic cost for businesses and communities. Rebalance Earth was established to make nature an investable asset class by structuring nature restoration projects as productive natural capital assets generating long-term contracted income. The fund targets UK urban and rural catchments where degraded landscapes compound water risk for infrastructure operators, utilities, food and beverage companies, and local authorities. West Yorkshire Pension Fund (LGPS) provided £25m in cornerstone seed capital for the RE(DARWIN) fund, recognizing nature-based resilience as a long-term institutional investment aligned with the UK Mansion House agenda. Solution in practice Rebalance Earth structures Resilience Purchase Agreements (RPAs) — long-term Nature-as-a-Service contracts — under which corporates pay for catchment-scale nature restoration (rivers, wetlands, peatlands) to reduce their operational exposure to flooding and water stress. The RPAs generate stable cashflows that service institutional investor returns. The platform uses AI, remote sensing, and geospatial mapping to identify and underwrite restoration projects, and applies independent measurement frameworks to translate ecological performance (e.g. flood peak attenuation, water retention) into contracted payment triggers. Rebalance Earth targets mobilizing over £10 billion in nature restoration capital across the UK over the next decade, with a live pipeline of catchment, coastal, and upland projects structured for institutional investment. Impact / outcome GBP 25m cornerstone from West Yorkshire Pension Fund; targets GBP 10bn+ of nature restoration capital over a decade. Next steps A coalition could work with Rebalance Earth and institutional asset owners to standardize RPA contract terms and ecological performance metrics across catchments, enabling replication in additional geographies and asset classes.
