Nash Gierak is the founder of Bold Green Strategies, a London-based sustainability consultancy. Nash works with a range of businesses—from start-ups to well-established companies—to help them confidently meet (and exceed!) the sustainability standards within their industries.

By adhering to minimalist values, she is able to streamline and simplify processes for clients to create cost, time, and space-efficient solutions. For an idea of the varied scope of her work, Nash advises on all aspects of a supply chain, including agriculture, freighting, welfare, packaging, sourcing, and provenance. She also creates bespoke training programmes, contributes copy to tender literature, draws up intersectional and multidisciplinary sustainability strategy and policy documents, and oversees accreditation with bodies including ISO, and B. Corp.

Nash is a GRI Certified Sustainability Professional and holds a BA (Hons), and an MA, for which she was awarded a scholarship. She is an experienced commissioned writer and regularly turns around content for press and digital platforms.

Nash has since developed a niche and is a respected voice in the food and events industries. In the summer of 2022, Nash took part in a panel discussion at Wilderness Festival chaired by The Guardian's Clare Finney. She appeared alongside chefs Will Devlin, Harriet Mansell, and Sam Buckley discussing what the British country and seaside can offer to replace ingredients usually imported from countries across the globe. She is part of the Unique Venues of London sustainability roundtable for caterers focused on the shared aim of creating beautiful sustainable events at the capital's most prestigious venues, including the Historic Royal Palaces, the Natural History Museum, and the Design Museum.

Her current clients include Social Pantry, Plain Jane Events, and 34 Bloomsbury.

Nash is a Fellow of the Royal Society of Arts, and an Associate Carbon Literacy Tutor at Positive Planet.
