With more than 6,000 acres of habitat creation underway, Environment Bank is dedicated to nature recovery as the solution to tackle the critical issue of biodiversity loss and ecosystem collapse.

Working in close collaboration with Natural England and the Department for Environment, Food & Rural Affairs (Defra), the Environment Bank team have helped shape nature recovery policy and guidance in the UK – one of the most biodiversity-depleted countries on earth – leading to the successful implementation of biodiversity net gain (BNG), an essential piece of environmental legislation passed in the UK.

Our team has generated enough Biodiversity Units to ensure an effective legislation rollout in early 2024. The recovery sites created to generate these Biodiversity Units is providing many landowners and farmers across England with a welcome income diversification opportunity alongside enormous benefits to local communities and ecosystems.

Our ambition doesn't stop with BNG – working alongside leading biodiversity related organisations and policy makers such as Taskforce on Nature-related Financial Disclosures (TNFD), Science-Based Targets Network (SBTN), and UK Business and Biodiversity Forum (UKBBF), we are now excited to offer nature based solutions, enabling businesses to meet their nature positive goals through our Nature Shares product.

Our level of investment and expertise sets us apart from many other environmental organisations. Environment Bank is part of the Gresham House British Sustainable Infrastructure Fund (BSIF II) portfolio, which operates with an investment philosophy to provide real asset-based solutions to environmental and societal challenges. We have secured £240m to establish landscape-scale recovery sites managed with the highest levels of ecological integrity.

Gresham House is a specialist alternative asset management group, dedicated to sustainable investments across a range of strategies, with expertise covering forestry, housing, infrastructure, renewable energy and battery storage, public and private equity with assets under management in excess of £6bn as at December 2021.
