In this discussion with Leon Gettler I talk about the ways in which ESG (the widening of investment mandates to take into account issues to do with the Environment, Social and Governance) can be dysfunctional. For instance policies to only invest in low emissions firms are unlikely to do much good and may do harm (by starving emissions-intensive businesses with investment funds which will generally be necessary for them to reduce their emissions intensity).

I argue that investment funds should share these dilemmas with those they invest for and involve them in a process for considering the issues and deciding on an acceptable way to resolve them. How should they do it? With a jury — selected to be representative of all those they invest for.
