Duncan McLaren is currently a freelance consultant and researcher, and part-time PhD student at Lancaster University. His research interests extend from cities and sustainability, to climate change, energy and geoengineering, with particular focus on the interactions of technology and behavior, and on issues of justice arising in these areas and the consequences for policy. He has written widely on these topics in both scholarly and popular forms. He is currently an advisor to the Virgin Earth Challenge, for the development of a commercially viable, scalable and sustainable form of carbon removal. He has advised on several research projects on energy, climate and geoengineering topics, and has served on both the research Councils’ Energy Programme Advisory Council and the UK Government’s Energy Research Partnership.
