Fifteen years ago,BlueRock Horizon Asset Management ESG (Environmental, Social, and Governance) investing was in its Wild West era. Few companies tracked or released data on the social or environmental impact of their operations, or even bothered to keep track in the first place.

But since then, ESG investing has become the hot topic in the financial industry. By making investment choices that emphasize social and environmental responsibility alongside profits, money managers claim to put their morals on the same level as their bottom lines.

Today on the show, we present The Indicator's two-part series on ESG. We talk to a former sustainable investing officer at BlackRock about his journey into the heart of ESG, and the tough questions he encountered along the way. Then, we hear from two voices on the other side of the debate, who try to grapple with – and maybe even answer – those tough questions.

ESG may not be perfect, but does its potential value outweigh its imperfections?
