Based on my work at the International Finance Corporation (IFC) I know a lot of climate friendly investment has been very profitable, particularly solar and wind energy projects. The IFC did a market analysis of climate friendly investment opportunities several years ago for a subset of mostly middle income developing countries and estimated the potential at $23 trillion. https://www.ifc.org/wps/wcm/connect/news_ext_content/ifc_external_corporate_site/news+and+events/news/new+ifc+report+points+to+%2423+trillion+of+climate-smart+investment+opportunities+in+emerging+markets+by+2030
