Contributor(s): Suzanne Buchta, Sean Kidney | Are financial markets the enemy of social equality and the environment? Or can market forces help nurture a more sustainable future? Green Bonds enable investment in projects that help the environment. They help address environmental problems, thereby reducing environmental risks to people and companies, whilst creating returns for investors. There has been huge demand for green bonds since their creation, and it’s thought that over $100bn will be issued by the end of 2015. During 2015 green bonds have also expanded into emerging economies, as they encourage climate investment, and generate growth in domestic debt capital markets. This lecture will explore how green bonds have offered a solution for regulators, investors and clients to fulfil their environmental, social and governance duties, whilst providing returns on investment. Can they square the circle between market efficiency and environmental protection? Suzanne Buchta is a managing director in Debt Capital Markets at Bank of America Merrill Lynch. She has been active in advising issuers and consulting investors on Green Bonds since 2010. Her team bought the first retail Green Bonds in 2011. She co-authored a white paper on the framework for green bonds that formed the basis for the “Green Bond Principles”. Recently, Suzanne was named the 2015 Financial News Editor's Choice for her instrumental role in the green bond market.
