“Climate finance was a major focus at the recent COP28 summit, but one set of game-changing institutions remains largely missing in such conversations: central banks,” writes Jennie Stephens, professor of sustainability science and policy, with Martin Sokol, of Trinity College Dublin. “Long-term stability cannot be achieved without first disrupting and transforming the existing financial system,” they argue, citing new research. “One way to do this would be for central banks to use tools already available to them to trigger a short-term intentional disruption in order to redirect financial flows and create greater stability in the long-term.”
