Why your ESG rating score is probably lower than your actual performance

Most unexpectedly low ESG scores trace back to disclosure gaps, not performance gaps. MSCI models a conservative estimate for anything you don't disclose, and its models are deliberately cautious. Sustainalytics assumes a risk is unmanaged if no management evidence is disclosed for it, even where a robust programme genuinely exists. CDP scores a blank question zero, full stop. None of these agencies phone to ask why the field was left empty.

Five causes explain most of the gap between a company's real performance and its score: inconsistency between the rating submission and the assured sustainability report (different Scope 1 figures in two places gets flagged or conservatively adjusted); high-weight questions answered vaguely because the team preparing the submission doesn't know which questions actually carry the most weight in that agency's methodology; policies referenced but not made publicly available, which several agencies simply won't credit; Scope 3 emissions under-disclosed even though climate-focused methodologies weight them heavily; and verified or certified data that exists but was never explicitly referenced in the submission, so the credit it should earn goes unclaimed.

The fix in almost every one of these cases isn't better sustainability performance, it's a pre-submission review that checks completeness, cross-references every figure against other public disclosures, and confirms that every verification or certification you've actually earned is claimed in the submission rather than sitting unmentioned in a filing cabinet.
