Steve Malkin
Planet Mark
“I’m so pleased to have Jessica McCormack join us at Planet Mark. The company shows that beauty and sustainability can go hand in hand, and the ethos of the brand is in a prime position to make great strides to reduce its carbon footprint, and serve as an exemplar to the industry as a whole. Measuring the brand’s carbon footprint and pledging to reduce it is the first step in that journey. I look forward to working more with Jessica McCormack and seeing the progress made.”

Certification story

First year certification is based on the commitment to continuous improvement in sustainability in its business operations by measuring and reducing its carbon footprint and engaging its stakeholders. 

Jessica McCormack has often talked of the value of sustainability and incorporated sustainable principles into her work. Much of McCormack’s work involves the circular principles of reworking vintage jewellery and jewellery boxes for the modern customer. ‘Upcycling’ is embedded into the work McCormack does, often working directly with client’s existing jewellery to help them revitalise collections. McCormack’s philosophy is that diamonds are to be worn, not locked away and wasted.

Luxury brands must seize the opportunity created as customers long for sustainable products. The sector is at an inherent competitive advantage, with products and relationships with customers designed to stand the test of time, and an emphasis on quality over quantity. However, this ethos must be combined with an objective and scientific approach to sustainability that encompasses a company’s entire supply chain. 

Future targets

Reduce carbon footprint by 5% annually

As part of the Planet Mark certification, Jessica McCormack has committed to making a year-on-year reduction.
