The Bank of Italy has published a new paper in its “Markets, infrastructures, payment systems” series examining how “Fintech for Good” (F4G) can support sustainable financial development and arguing for safeguards to ensure such initiatives are credible. The paper proposes an operational definition of F4G, setting out its core characteristics and areas of application, and frames F4G as technology-driven innovation aimed at specific environmental and social goals and at promoting financial inclusion in line with the United Nations Sustainable Development Goals. It also makes the case for introducing a regulatory framework to mitigate the risk of false claims about the adoption of environmentally sustainable measures and to ensure F4G initiatives align with measurable and verifiable sustainability objectives, alongside promoting public-private collaboration and strengthening financial education programmes.
