Modern society is unsustainable: biodiversity loss is occurring at an unprecedented rate; anthropogenic activities dominate material cycles, putting upward pressure on resource supply; and the industrial system is forcing Earth’s climate towards the brink of a critical transition, on a scale never before experienced by humans. Facts such as these highlight the imperative for transformational change to the industrial system and also the materials basis of modern society. Traditional materials research approaches focus on improving properties and performance of individual technologies at relatively high technical detail. On the other hand, common sustainable engineering methods such as material flow analysis and life cycle assessment are used to study material and product systems at relatively low technical detail. In this talk I present a sustainable materials system research agenda. This agenda aims to address key contemporary sustainability challenges like climate change mitigation by integrating deep technical analysis of material technologies into a whole systems modelling perspective. I will focus on cement related materials such as concrete: this material is responsible for ~50% of all materials extraction and 8-9% of anthropogenic CO2 emissions, yet also provides unique opportunities for beneficial use of industrial by-products and wastes.

Steinberger, Professor of Social Ecologiy and Ecological Economics at the Sustainability Research Institute of the University of Leeds, Faculty of Environment, School of Earth and Environment, UK. Her research examines the connections between resource use (energy and materials, greenhouse gas emissions) and societal performance (economic activity and human wellbeing). She has a PhD in Physics from MIT in the USA, and subsequently worked at the Universities of Lausanne, Zurich, and the Institute of Social Ecology in Vienna. She is the recipient of a Leverhulme Research Leadership Award for her research project 'Living Well Within Limits' <http://lili.leeds.ac.uk/>and a Lead Author for the IPCC's 6th Assessment Report.
