In August 2018 Ethical Consumer received a questionnaire response from Amberoot.
Amberoot was an online marketplace for clothing. It stated that brands on its website must abide to these non-negotiable minimum social standards: no forced labour, no child labour and an ability to work in safe and healthy working conditions earning a living wage.
It said, "Additionally, all brands we work with uphold high social welfare standards. Most of the products we sell have FairWear, Fairtrade, BCorp Certifications which ensure that workers throughout the supply chain are treated fairly."
Amberoot provided consumers with transperant information regarding a products supply chain.
It said "We are a first retailer worldwide providing supply chain information for all multi-brand products that we sell. Publicly visible supply chain information shows that our brands have nothing to hide. You can trace back in which locations and institutions (farms, factories) the work was undertaken for each and every product. This enables us to see how environmental and social standards are upheld throughout whole supply chain."
With regards to non compliance it said, "In case we will become aware of any proof (/-s) that any brand we work with does not uphold to the aforementioned requirements throughout their whole supply chain we will ask for the brand to take remedial actions. If the brand won’t take any subsequent immediate action (/-s) to improve the issue we will stop selling their products at Amberoot."
Ethical Consumer deemed Amberoot to have an effective if not explicit policy addressing workers' rights within its supply chain due to the fact it provided consumers with information regarding suppliers supply chains.
