Marle / Commitments and Certifications

From our production methods to our garment design, raw materials and working conditions through to our environmental and social impact, we are proud of who we are at our essence. We want to set an example for other, bigger and upcoming brands, hopefully inspiring them to do the same - because sustainability isn’t something brands could be doing, it’s something they absolutely should be doing. This means we are continually assessing every aspect of our business - we are committed to learning, growing and evolving to meet the moving and sometimes blurry goalposts of being a responsible business. 

We deliver our garments in biodegradable bags made of corn starch and our care labels are 100% cotton. We eradicated our use of single use plastic within our office, including the bags in which our products are shipped in.  We’d always used recyclable bags but worked hard on creating our own compostable bag. They’re TUV certified and we can proudly say break down within a few weeks – tried and tested by our team at HQ.  For packaging, we use third party suppliers such as Porter Packaging and for our online orders, they are sent in compostable bags or recyclable cardboard bags. Our tissue paper is supplied through No Issue tissue who have their sustainability journey available online here

We reduce our impact through safe and minimised use of chemicals and when possible, we work with un-dyed fabric which conserves water, energy resources and reduces the overall footprint of the garment.

We choose sea freight over air shipments. Air freight has a Co2 emission over 40 times sea freight. Our offices have an environmental focus with our staff encouraged to take part in recycling schemes.

Some of the key certifications our fabrics, suppliers and business holds:


Business Social Compliance Initiative (BSCI) supports companies to drive social compliance and improvements within factories and farms throughout their supply chain. Our factories are either BSCI or WRAP Certified (or both).

Global Organic Textile Standards (GOTS)

GOTS is the worldwide leading textile processing standard for organic fibres, including ecological and social criteria, backed up by independent certification of the entire textile supply chain. Marle organic cotton pieces are either GOTS or OCS Certified.

Global Recycled Standard

The GRS is an international, voluntary, full product standard that sets requirements for third-party certification of recycled content, chain of custody, social and environmental practices and chemical restrictions. Our factories are all aligned with this standard.

Majority of our knitwear and silk pieces carry this certification.
