Climate policy increasingly relies on techniques to remove CO2 from the environment as a supplement to cutting emissions: counter-balancing residual emissions in 'net-zero' and reducing atmospheric concentrations of CO2 to safer levels. In this talk, Duncan will survey how cities are engaging with carbon removal – reviewing the realistic scope of possibilities such as carbon negative building materials, and carbon removal through urban waste management; and suggest ways in which urban carbon removal could be governed to contribute to goals of justice and sustainability. Duncan McLaren is currently a Research Fellow with the Institute for Responsible Carbon Removal at American University. His research examines the politics and implications for justice of novel technologies, particularly using public engagement methods. Prior to his PhD studies, completed in 2017, Duncan worked as an environmental researcher and campaigner, most recently as Chief Executive of Friends of the Earth Scotland from 2003 to 2011. He has advised and consulted for research and financial institutions, government departments, philanthropic donors and non-governmental bodies on energy, climate, urban and sustainable development issues.
