It’s tough to get on Barron’s 100 Most Sustainable Companies list.

We should know. We created it.

Barron's + Calvert

Lots of companies say they’re contributing to a better tomorrow. We put those claims to the test with a unique, rigorous approach to research.

Our Partnership

Barron’s relied on us to identify which companies are showing leadership in addressing the environmental, social, and governance (ESG) risks that are relevant to their operations.

Creating the List

To create the list, we rated the 1,000 largest (by market capitalization) publicly held companies headquartered and incorporated in the United States on their responsibility in five key stakeholder categories:

  • Shareholders (e.g., accounting policy, board structure)
  • Employees (e.g., workplace diversity, labor relations)
  • Customers (e.g., business ethics, product safety)
  • Community (e.g., human rights along the supply chain)
  • Planet (e.g., greenhouse gas emissions)

Research Team

To help enhance shareholder value and improve societal outcomes, we examine companies’ environmental and social exposures, as well as their governance structures. Our goal is to help investors manage risks while influencing outcomes that create positive change.

Our Approach

Our research team has a sophisticated and rigorous methodology that’s paired with decades of leadership in responsible investing — it’s at the heart of everything we do.

We parse thousands of ever-evolving data points from external data vendors to differentiate companies’ management teams on financially material ESG issues, informing our security selection and corporate engagement. Rely on us for insights into the current state as well as future trends and opportunities.
