HSBC publishes its “sustainability risk policies” (a public version of them anyway). They are fairly general, but what I find interesting is that they follow various international conventions from the UN, World Bank, and others in making lending decisions. Examples include the Paris convention and the Ramsar wetland convention. So even if politicians in certain countries deride these international bodies and conventions as being a lot of hot air, they can in fact have a large impact when adopted widely by public and private actors around the world.
