Sonos publishes detailed emissions data, with third-party verification of Scope 1 and 2 but none for Scope 3. Emissions rose 5% year-on-year despite a lower long-term level. Water use is not reported, nature impact is unquantified, and recycled content in products remains modest. Targets lack SBTi validation.
