Dyson refuses to disclose any emissions data despite $8.3B revenue and 14,000+ employees across global manufacturing. No Scope 1, 2, or 3 reporting; no science-based targets; no sustainability report. The company claims 2030 carbon neutrality without methodology. Renewable energy covers only owned operations, not contract manufacturers.
