Simply put there are 3 dimensions which corporates have to consider:
1. Their contribution to greenhouse gas emissions and other environmental pollutants. 2. Their own exposure to physical climate risk (can they quantify it?) 3. Their compliance to reporting standards and regulations regarding climate change and other environmental issues.
Large investors increasingly want to know (a) how they contribute to climate change via their investments and (b) their risk exposure to climate change risk, via the businesses they are invested in.
Corporations have to realize that their large, institutional, investors are way beyond debating climate change and are taking action. Like it or not.
