To reach our Paris Agreement commitments and build back better from the COVID19 crisis, trillions of investments will be needed. Mobilising international private capital and scale up cross-border green investments will be crucial. The International Platform on Sustainable Finance was created as a response to this urgent need. The IPSF promotes integrated market for environmentally sustainable finance, which will facilitate cross-border capital flows into green projects and reduce transaction costs. The work of the IPSF will be central to the development of global sustainable finance standards.
