The Investment Bank for Earth
A not-for-profit organisation powered by investment bankers. We use financial advisory, investment banking, and principal investing expertise to accelerate positive change for people and the planet.
About BwB
Founded in London in 2013, BwB is a not-for-profit financial innovator powered by investment banking expertise. Our mission is to facilitate high-impact projects that benefit the environment and promote social good.
Governments do not have balance sheets big enough to address the world's environmental and social problems. Mobilising capital — a core competency for investment bankers — is a key part of the solution. Repurposing financial expertise to maximise impact rather than income is embedded in our DNA. An FCA Appointed Representative with offices in the UK, Ireland, Singapore, and UAE.
Designing innovative financial instruments that unlock capital for sustainability projects.
Connecting high-impact projects with institutional investors, DFIs, and sovereign wealth funds.
Tracking measurable environmental and social outcomes across 110+ cities in 30+ countries.
The Scale of the Challenge
Less than $102 billion flows today. BwB exists to close that gap — mobilising the private capital that public finance cannot provide alone.
We are not waiting for governments to act. We bring finance expertise to where it matters most.
Our Focus
Spanning the breadth of environmental and social finance — from blue economy to sovereign debt restructuring.
Impact in Action
BwB worked with RARE Conservation to design a blended finance structure enabling coastal communities across the Pacific Islands to access blue carbon markets. The model combined grant funding with revenue-linked bonds, enabling sustainable fishing practices while generating measurable carbon credits.
“The BwB team provided us with valuable input and structuring to help refine the initial concept to attract institutional and private capital.”
