For a long time entrepreneurs, investors and advocates of sustainable investing have spoken longingly about the $2 trillion of institutional investor dollars that have been reputed to be sitting skeptically on the sidelines, teasing everyone with the prospect of finally putting their sizeable investment muscle to work to scale the sector. Throughout this period, institutional investors have argued that they have withheld their dollars over sound investment concerns with the sector. For a number of years, innovative entrepreneurs in growth sectors like food, energy, water and waster have been doing the heavy lifting to demonstrate that some of these smaller-scale projects can provide attractive investment returns for those investors willing to step in and pioneer these structures. Institutional investors are taking notice. Now a new investor survey and report issued by Bright Harbor Advisors, a private fund advisor, provides some compelling evidence that institutional investors are warming to sustainable investing. 81% now have some type of sustainability, impact, or ESG [Environment, Social, and Governance] mandate as part of their formal investment policy. And an increasing number are allocating internal resources to implement these policies. About a third of respondents have someone on their team dedicated to the space and nearly 20% have sustainable private fund managers in a dedicated investment bucket.
