Corporate Knights is a Toronto-based media + research outfit with a heart for accountability, sustainability, and pushing business toward long-term value — not just instant profit. They didn’t show up yesterday. They’ve been working since 2002 to shift how people think about corporate success.


Who They Are, What Drives Them

  • The company was founded by Toby A. Heaps, Paul Fengler, and Peter Diplaros. Their idea: after the big accounting scandals of the early 2000s (Enron, WorldCom), there was a longing for business that actually did what it said — trust-worthy, transparent, socially conscious.
  • Their mission is clean capitalism: where business decisions account for environmental, social, and governance (ESG) consequences — not just the bottom line.

What They Do

  • Media / Magazine: They publish a quarterly magazine that digs deep into climate change, responsible investing, innovations in sustainability, etc. It’s not superficial — they try to shine light on what works, what fails.
  • Rankings & Reports: Probably what Corporate Knights is best known for. They produce things like:
    • Global 100 Most Sustainable Corporations in the World — a yearly list of big public companies doing sustainability well.
    • Best 50 Corporate Citizens in Canada.
    • Also other indices, like sustainable cities, future-50 fast growth companies aligned with clean economy, funds & ETFs rated by ESG metrics, etc.
  • Financial & Research Products: They track how companies are doing in things like “clean capex” (capital expenditures that drive sustainability), how R&D aligns with green goals, etc. So, not just narratives, but measurable stuff.
  • Advocacy & Policy Engagement: Their work is not just watch-dogs. They help shape public policy, partner with governments and companies, push for change. They believe systems-level work is necessary for bigger impact.

Why They Matter

  • They make “sustainability” something you have to measure. Many companies can make vague green claims, but Corporate Knights demands metrics, rankings, independent research. That creates pressure and accountability.
  • Their rankings & indices are widely cited. It gives them legitimacy, visibility. If you make the Global 100 list, people notice.
  • They bridge business AND ethics: encouraging companies to see ESG issues not as luxury or noise, but a core part of long-term risk, reputation, innovation & competitive advantage.

Some Tension Points & Realism

  • It’s not always easy for companies to align what they say with what they do. Rankings expose discrepancies, which leads to criticism (sometimes valid) for greenwashing or superficial sustainability gestures.
  • Measuring ESG is hard. Data quality, consistency, global comparability — these are ongoing hurdles. There’s risk of “apples vs oranges,” where companies look good on some metrics, bad on others. The devil is in the details.

Big Moving Pieces

  • Their Global 100 ranking is released every year during the World Economic Forum in Davos — that gives it global visibility.
  • They expanded into measuring sustainable revenue, clean R&D, clean acquisitions — meaning they’re not just asking, “Is the company trying?” but “How much of what you do is clean / sustainable?”
  • Also, notable is that Corporate Knights pushes for public policy: they believe systemic infrastructures (regulation, incentives, standards) matter just as much as voluntary corporate efforts.

If I were telling someone why Corporate Knights is one to watch, I’d say this: they’re like the keeper of the scoreboard in the ESG game. Without a scoreboard, companies tend to overpromise and underdeliver. They give people (investors, consumers, governments) the metrics to see who’s really playing fair — and who’s using “sustainability” as PR.
