Stewart joined Bioregional at the start of 2020 to work on sustainable products projects, looking at energy and water efficiency, use of sustainable materials, and embedding circular economy principles in design and supply chain practices.
Stewart started out as an environmental and analytical chemist, but after a few years in the lab decided to change tack and work in the energy-efficiency sector at the Energy Saving Trust. Energy-efficient products became his area of focus – Stewart was involved in lab testing campaigns, making policy recommendations, certification programmes and consumer advice projects for efficient appliances, electronics, lighting, boilers and other products that could enable people to save energy in the home. More recently, this area became relevant to SDG7 on improving energy access – he also worked as part of the Efficiency for Access coalition supporting the market for high-efficiency appliances, designed to operate on solar home systems and mini grids in Africa and Asia.
