Directors

Tommy Wiedmann is Director of Research at the Centre for Sustainability Accounting. He is founding member of the company and develops the methods and data needed for integrated sustainability accounting. He is also a Senior Research Scientist at CSIRO Ecosystem Sciences in Canberra, Australia, and an Honorary Associate Professor at the University of Sydney, Australia.

Tommy's scientific interests are in the field of sustainable consumption research where he focuses on improving and applying carbon footprint and environmental input-output analysis. He was guest editor of the Special Issue 2009 of the journal Economic Systems Research on 'Carbon Footprint and Input-Output Analysis'. He was a member of the 'Methodology' Technical Working Group preparing the Greenhouse Gas Protocol Product and Value Chain (Scope 3) Standards and of the Economic-Environmental Accounting Peer Review Panel of the Scottish Government. In 2009, he gave evidence before the Transport, Infrastructure and Climate Change Committee of the Scottish Parliament.

Tommy holds a PhD in environmental and analytical chemistry from the University of Ulm, Germany.

Dr. John Barrett
John Barrett is a Director at the Centre for Sustainability Accounting and is also a Professor of Sustainability Research at the University of Leeds. He joined the Sustainability Research Institute (SRI) at Leeds in February 2011. Currently, John is lead author for the IPCC 5th Assessment for Working Group III.

John was one of the lead advisors to Defra in relation to the development of PAS2050, and was commissioned by Defra to lead on understanding the carbon footprint of trade. John has appeared regularly on Radio 4 news and discussion programmes and written numerous policy reports on SCP issues, for a wide range of audiences.

Key areas of his research have included the use of global trade models to understand the embedded carbon emissions in goods and services, and estimating the upstream carbon emissions from emerging energy technologies. These have been used by numerous UK government departments to understand consumer emissions, as well as the carbon emissions embedded in products.
