Impact investing aims to generate both financial returns and positive social/environmental impacts. It has grown significantly since 2008 to around $250 billion globally across sectors like energy, housing, food and agriculture. A results-based approach ties payments to outcomes or impacts achieved, with commissioners defining desired outcomes, investors providing funding, and service providers developing solutions. Social, environmental, and development impact bonds are examples where private capital funds preventative services, with investors recouping funds and earning returns based on results. Defining and measuring outcomes allows money to be used proactively and data-driven to support well-being in a collaborative, results-focused way.
