Seasalt's footprint was 42,620 tCO2e in its 2024/25 year, more than 99% of it from its supply chain, and Which? reports that its total rose again in 2024 even though its own operations' emissions are 88% lower. It says its near-term targets are SBTi-validated, but its supply-chain target is intensity-based and is being revalidated. Its cotton, wool, viscose and leather are all certified and it runs take-back and resale, but it publishes no water data.
