"At Barclays we see green and sustainable finance as the future." Luke Davies, Vice President in the Group CEO Office of Barclays and One Young World Ambassador, tells Edie Lush about how and why the company built its green banking initiative. He stresses the importance of renewables, green tech and low carbon businesses, but adds that the bank saw a commercial opportunity and that has helped the business sell the concept to shareholders and clients. Thanks to @OneYoungWorld for helping us arrange these interviews with these inspiring young leaders.
