Assets in sustainable, responsible and impact investment assets reached almost $31 trillion by the start of 2018, up 34% from 2016, and they grew at even faster rate in the U.S., according to the Global Sustainable Investment Alliance (GSIA). Sustainable investments in the U.S., including assets chosen based on their environmental, social and governance ratings, increased at an even faster rate, rising 38% to $12 trillion and accounting for 26% of all professionally managed assets. In the past year, many asset managers including Vanguard, Fidelity, BlackRock and Nuveen have introduced sustainable and/or mutual funds or ETFs that choose investments based on their ratings for ESG criteria. In addition, about 200 funds not previously focused on ESG ratings have added ESG considerations to their investment process. BNP Paribas has taken an even more favorable stance toward sustainability, adopting an ESG overlay for all its investment strategies.
