ESG Lawsuits in 2023: What’s Heating Up

In 2023, the world of ESG isn’t just about pledges, press releases, or fancy reports anymore. It’s getting litigious. Companies are facing lawsuits, regulators are sharpening their knives, and claims of “green” behaviour are being scrutinized like never before. This story maps the legal landscape—not to scare companies, but to push everyone into being more honest, more transparent, and more prepared.


What’s Going On Under the Hood

  • Greenwashing & Misrepresentation
    Many lawsuits are popping up because companies made sustainability or environmental claims that weren’t backed up. Things like calling products “eco-friendly,” “recyclable,” or “sustainable” when the reality is fuzzy. Regulators and courts are saying: if you’re going claim it, be ready to prove it.
  • Legal Tools Being Used
    • Consumer protection laws, competition acts, or securities regulation are starting to bite.
    • Class actions are becoming more common, especially where misrepresentation is alleged.
    • Investors aren’t safe either — they can (and are) suing over omissions or misleading statements.
    • In Canada, there are also climate-change cases, Charter rights claims, and judicial reviews tied to ESG commitments.
  • Not Just Canada—Watching the U.S. Too
    The U.S. landscape shows similar trends: suits alleging false sustainability claims; lawsuits threatening big brands for vague or unsupported “green” language. These act as signals—what happens there tends to ripple elsewhere, legally and in public expectations.

Risk Warning: It’s Real, It’s Growing

If you’re running a company (or advising one), these are not theoretical risks anymore. Public statements, marketing materials, even packaging—all of that can trigger litigation if promises don’t match performance.


What Companies Should Be Doing

To stay safe and credible:

  1. Audit every ESG claim — Are they realistic? Verifiable? Backed by data or third-party assessments?
  2. Tighten up disclosures — Don’t leave room for misunderstanding. Be clear about what you mean, how you measured, what trade-offs there are.
  3. Check the supply chain — Your ESG promises aren’t just about what you do, but what your suppliers do too. Gaps there can expose you.
  4. Avoid vague aspirational language unless it’s supported and you truly believe you can meet those aspirations.
  5. Governance & oversight matters — leadership, D&Os, boards need to know what’s being said in public and make sure it aligns with action.

Why This Matters

ESG used to be something nice companies did if they could. Now it’s something they must do carefully — because legal risk + public trust + investor scrutiny all make vague claims dangerous. The companies that will avoid trouble are not necessarily the biggest or richest, but those who embed honesty, clarity, and accountability into their ESG story.
