Efforts to create healthier and more environmentally sustainable communities are gaining momentum at both the local and global level. Worldwide, investors are increasingly applying Environmental, Social and Governance (ESG) screens to drive corporate practices that reduce harm to the environment and increase transparency in reporting environmental practices.

How are investors designing and executing these portfolios? What research and partners are involved? What are the costs?
