Meet the woman behind our most sustainable jeans ever


As a young child, Cerian learnt all about textiles from both of her grandmothers and early on, she developed a passion for dressmaking and embroidery. This led her to study Textiles and Apparel at university before stepping into the industry and working for some of our long-standing supplier partners for over 20 years – much of which was spent overseas in Asia.

Over 18 months ago, Cerian joined the M&S Clothing & Home team as a Senior Sustainability Manager (Environment & Chemicals) – a role that’s crucial to ensuring all our leading sustainability standards are being met. Cerian works with all our fabric suppliers to ensure they are meeting our sustainability standards and the chemicals are used responsibly and safely to limit their impact on the environment.

Not long after joining, Cerian got stuck into an extremely ambitious project to launch brand new sustainability standards for all our denim – one of our most popular hero categories as we sell 1 in 10 jeans on the high street.

Cerian worked hard, together with our sourcing offices, suppliers and partners, to create a programme to measure and reduce the environmental impact of all our denim. As a result, each and every one of our 5 millions pieces of denim is now made with 100% responsibly sourced cotton, 86% less water* and kinder chemicals. The latest range sourced to these principles launched just a few weeks ago and more detail can be found here.

“I love how varied my role can be, from rolling out our environmental audits to ensure our suppliers are meeting our standards to working with our product teams to push the boundaries of our sustainability standards – like what we’ve done with denim," says Cerian.

“At M&S, I work alongside many talented and professional women – be it in the product development teams or the technical teams. I feel like I always have a voice and my specialist knowledge and expertise is recognised and respected by the business. I feel so proud to have the opportunity to work for a company that puts sustainability at its heart and is always committed to doing more. I’m so excited to continue our sustainability journey at M&S and be part of the promise we make to our customers that our clothes don’t cost the earth.”
