Dr Yvonne Lewis is a principal consultant at The Green House and specialises in the quantitative assessment and modelling of systems in support of the strategy, policy support and scenario and futures work. She also has a keen interest in sustainability metrics and indicators. Yvonne has an undergraduate degree in Chemical Engineering (awarded with Honours) from the University of Cape Town, South Africa, and obtained her PhD from the University of Sydney, Australia. Yvonne’s PhD focused on extending the capabilities of Life Cycle Assessment to include impacts from solid waste management, particularly in mining, minerals processing and coal combustion context. This linked different types of systems modelling (both process and environmental) and included risk assessment elements. After completing her PhD in 2004, Yvonne took up a post-doctoral position at the Centre for Environmental Strategy, University of Surrey, England. Here, she worked in the field of LCA, focused on carbon added and value-added along with the chemicals, metals, and building material supply chains. She also contributed to the development of a multi-criteria approach to assess the sustainability of bioenergy systems. After returning to South Africa, Yvonne worked at the African Centre for Cities at UCT where she applied her quantitative analysis skills to the urban context, developing sustainability indicators and calculating ecological footprints and carbon footprints for cities. In this role, Yvonne helped to co-ordinate the Climate Change Think Tank – the City of Cape Town’s collaborative research initiative and also spent some time as co-director of the Cape Urban Observatory.
