In February 2018 Ethical Consumer received a questionnaire from the Conscious Consumer Ltd (Mamoq). In response to a question regarding its environmental policy it stated "While we do not have an official policy, our whole ethos is about supporting brands that produce with respect for the planet, and its inhabitants. Our office is located in the Future Business Centre which takes steps to reduce their energy consumption including recycling rain water in the plumbing, and use of solar panels. As a small two-person company (that bike to work!) we do our best to keep our footprint low, and as we grow as a company we will introduce more formal policies to monitor our consumption."
The company was an online market place for "ethical and sustainable" clothing brands. In order to be listed on Mamoq's website brands must have made a commitment to ethical and sustainable production and matched at least three of Mamoq's 12 values: artisan craft; cycled; eco conscious; economic empowerment; gives back; handmade; made in Europe; natural materials; organic; 3rd party certification; transparant; and vegan.
The company had a turnover of less of £10.2 million and was considered by Ethical Consumer to be providing an environmental and social alternative therefore it received a best rating for Environmental Reporting.

In February 2018 Ethical Consumer viewed The Conscious Consumer's website, mamoq.com, which listed clothing items made from leather, wool and silk. As a result the company lost half a mark under Ethical Consumer’s Animal Rights category.

With regards to leather the brand Issara was said have a "small, transparent supply chain." Mamoq's website stated that "They source hides from New Zealand, which is renowned for animal husbandry techniques and high animal welfare. The hides are tanned at a family-owned business in NZ before being shipped to Central Java and Eastern India where they are turned into Issara creations."
The brand Semura opts for vegetable-tanned leather that uses natural tannins found in the bark of trees.
There were several other brands which used leather - one was using scraps of leather and one was using natural leather. A shoe brand did not appear to have a policy on leather sourcing.
Leather, as the hide of a dead animal, naturally decomposes. To prevent this decomposition the leather industry uses a cocktail of harmful chemicals including trivalent chromium sulphate, sodium sulphide, sodium sulfhydrate, arsenic and cyanide to preserve it. Tannery effluent also contains large amounts of other pollutants, such as protein, hair, salt, lime sludge and acids. These can all pollute the land, air, and water supply making it a highly polluting industry.
Although some used vegetable tanning methods, the effluent from this still contains high levels of difficult to treat substances. As a result the company lost half a mark in the pollution and toxics category.

With regards to other animal derived materials. At the time of writing Mamoq did not appear to sell items of clothing made using down / feathers / angora or fur. However there was no policy to state that it would not ever sell products made from these items.

The company did retail products containing merino wool. In an communications with the company it stated "We ensure that all wool is Muelsing Free unless it is recycled / upcycled."

The company did retail products conatining silk. In communication with the company it stated "The only time silk worms are killed is when the silk comes from an end of roll materials eg: mayamiko which we still consider to be ethical as it is using materials that would otherwise be discarded."
