There’s so much more to finance than just returns, says alternative finance expert Tiara Letourneau (Cambridge Judge Business School MFin 2014). She believes that, used wisely, financial systems can make the world a better place, on both an individual and a global level. Letourneau is now based in Seoul, South Korea, in a new role – strategist at the Green Climate Fund. It’s a global platform, accountable to the United Nations, set up by 194 governments to respond to climate change by investing in low-emission and climate-resilient development. The private sector is needed to invest in projects that will enable the switch to low-emissions technologies, says Letourneau. It’s a big challenge – one of the biggest. And to Letourneau, it’s yet another opportunity to use financial systems to make the world a better place.
