Dyson publishes no emissions data despite $8.3B revenue and 14,000+ employees, refuses Scope 1, 2, and 3 disclosure, and makes an unvalidated 2030 carbon-neutral claim. A major electronics manufacturer outsourcing most production to contract makers while hiding its footprint. No sustainability report, no SBTi alignment, no biodiversity policy.
