Charnett has a Biochemical Engineering background and specialises in applying life cycle thinking to analyse the environmental impact of product and systems - life cycle assessments (LCAs). She has applied the LCA methodology across sectors, including consumer/packaging, construction, and healthcare, advising on the sustainability of new interventions and/or implementations to our current and future systems. During her time at the UCL Plastic Waste Innovation Hub and the Interdisciplinary Centre for Circle Metals, she worked as part of multidisciplinary teams with the aim to create lasting changes and assist project partners in taking steps towards a circular economy. She now works in the construction industry and is still interested in finding ways of using LCA as a tool for recognising more sustainable innovations and solutions for all sectors.
