Sustainability Insiders

Paula Gamester MBE, founder of the social enterprise Connector Media CIC and co-founder and of The Sewing Rooms, which upcycles, recycles and diverts textile waste from landfill, tells Kevin the story behind the creation of The Sewing Rooms, how she brought the thermal cooking bag to the UK to help tackle cost-of-living challenges and reduce carbon emissions, and gives her tips for running a sustainable social enterprise.For full transparency, this episode was recorded late in 2025 and The Sewing Rooms has since gone into voluntary liquidation. We recognise that many third-sector organisations like this are operating in difficult times, particularly in relation to available funding sources and rising costs. This episode is published because it has such an inspiring message and themes which remain as good learnings on sustainability for listeners in the fashion, third-sector and other industries.

Mary Aladegbola, Senior Net Zero Technical Energy Lead at NHS England, tells Kevin about the scale of the challenge at the NHS around sustainability, why a whole-systems approach matters, and gives her practical advice for sustainability leaders.

Kevin chats to Ewan Donald, the head of Environmental, Sustainability and Governance at specialist engineering contractor Ipsum, about building an ESG function from the ground up, the real-world challenges of decarbonising a large fleet, and how to adhere to clients' ESG expectations.

Camilla Smith, founder of Sustii, a recruitment agency which specialises in global sustainability, tells Kevin where she thinks sustainability sits within modern organisations, how the sustainability talent landscape looks today, and gives her advice on how to stand out as a candidate when applying for sustainability roles.

Kevin talks to Graham Duxbury, chief executive of Groundwork, about the employment opportunities within the sustainability space, real-world examples of how businesses and partners are working together to positive effect, and the support Groundwork offers to businesses.More information on Cadent Foundation's support to Groundwork:https://cadentgas.com/foundation-partners-projects/groundwork
