Abstract: The industrial sector emits almost 43 percent of the global anthropogenic carbon dioxide emissions to produce materials and products. Furthermore, energy is used to move materials and products and process the waste. Hence, a large amount of energy is consumed and CO2 is emitted to sustain our materials system. Until recently, studies investigating mitigation options focused on changes in the energy system. To assess measures to reduce materials consumption, fossil fuels consumption and CO2 emissions, detailed understanding of the material system is needed. In this presentation an overview will be given of the relation between materials and the carbon cycle focusing on the contribution of materials to anthropogenic carbon flows. The presentation will discuss opportunities to reduce CO2 emissions by improving the efficiency with which society uses materials through product design, material substitution, product reuse and material recycling.

Biography: Ernst Worrell (Ph.D.) is Manager Energy & Climate Strategies at Ecofys in The Netherlands, focusing on energy and climate strategies for industry. He has experience in a wide number of industries, e.g. cement, iron and steel, pulp and paper, glass, chemicals (e.g. fertilizers, petrochemicals, pharmaceutical), food (breweries, wine, corn milling), petroleum refining, and vehicle assembly. Ernst Worrell has led the industrial energy assessment work at Lawrence Berkeley National Laboratory in the United States since 1998. Until 1998 he co-led the energy efficiency group at the Department of Science, Technology and Society of Utrecht University, The Netherlands. He was a visiting scientist at the Center for Energy and Environmental Studies at Princeton University (USA) in 1994-1995, and a visiting professor at the Universidade de Sao Paulo, Brazil, in 1996. His work includes research and evaluation projects in industrial energy efficiency improvement, greenhouse gas emission mitigation in industry, energy efficiency benchmarking, energy policy, energy modelling, emission trading, energy and materials, and waste processing.

He has experience in multi-national research teams and has lead studies for various governments, the European Commission, World Energy Council and the United Nations. He was a coordinating lead author of the Special Report on Technology Transfer, a lead-author of the IPCC special report on Emission Scenarios, Third and Fourth Assessment Report. He is (co-) author of over 250 publications. He is Editor-in-Chief of the peer-reviewed journal Resources, Conservation and Recycling and associate editor of Energy, the International Journal and editorial board member of Waste Management. He is a member of the Roster of Experts of the Scientific and Technical Advisory Panel (STAP) of the Global Environmental Facility (World Bank and United Nations Environmental Program), Member Roster of Experts African Energy Policy Research Network (AFREPREN), and a member of multiple organizing and scientific committees of international conferences.
