I reviewed the GISD Alliance website (https://gisdalliance.org/), a United Nations–convened coalition of global business leaders representing roughly $16 trillion in assets, and confirmed its stated mission to catalyze finance through public–private collaboration, align finance and investment with the SDGs via improved measurement and reporting, promote long-termism, and develop instruments and platforms; recent outputs include guidance on sovereign SDG bonds and a Business Steering Committee for FfD4 (2025). This website is included in PART 2: The Purposeful Investment Landscape, Chapter 'Exploring the Landscape' because it concretely illustrates how large-scale private capital and corporate leadership can be mobilized and structured to advance the SDGs and highlights practical opportunities for long-term, sustainable investment.
