In this episode we speak with James Purcell, Group Head of Sustainable Frameworks at Credit Suisse. He has co-authored a new book called 'Sustainable Investing in Practice'. We talk to James why he wrote the book, what he is trying to achieve, and why sustainable finance shouldn’t be a difficult concept. He explains the dangers of polarisation and the importance of taking an accessible and scale approach to impact. James also expands on ESG data and why he feels for business leaders who are overwhelmed.
