Just Good Business: An Investor’s Guide to B Corps

Whatever your interest in Certified B Corps—supporting the triple-bottom line, their strength as investments that bring a more comprehensive set of risks into focus—this guide delivers what investors need to know about Certified B Corps and Benefit Corporations.


There is a profound shift underway in how capital markets value companies. So if you’re an investor, what do you need to know?

In partnership with Patagonia and wealth advisory firm Caprock, the Yale Center for Business and the Environment has released a new publication to answer this question. Entitled “Just Good Business: An Investor’s Guide to B Corps,” this report explores the distinct financial value offered by Certified B Corporations and Benefit Corporations.

"B" designations, created and overseen by the nonprofit B Lab, offer a certification program and legal framework by which companies can fold social and environmental impacts into their bottom line.

The B Corp movement is, to me, a product of a general improvement in our understanding of economic behavior. Through greater appreciation of the real motives that drive and excite people, B Corporations provide a significant new opportunity for investors. I think they could make more profits than any other types of companies, and this guide helps investors understand why.

—Robert Shiller, Sterling Professor of Economics, Yale University and Nobel Laureate
