Singapore International Energy Week (SIEW) 2019 Thinktank Roundtable H:

Climate Geoengineering:

A Realistic Option to Combat Climate Change?

Date: Friday 1st November 2019
Time: 9:00 am – 12:00 noon
Venue: Sands Expo and Convention Centre, Marina Bay Sands, Singapore

SIEW ESI micro website:


The continuing inability of the world to effectively tackle rising greenhouse gas emissions and increasing evidence of the impacts of climate change is making geoengineering more attractive as a strategy for countering rising temperatures. Several possible technologies have been touted as options for reflecting sunlight away from the earth’s surface. These include aerosol injection, marine cloud brightening, high-albedo crops and buildings, ocean mirrors, cloud thinning and space sunshades. Aside from direct carbon capture from industrial infrastructure, potential carbon removal techniques include large scale afforestation, soil carbon enrichment, ocean iron fertilization, enhanced weathering and ocean alkalization. Each of these techniques carries risks, not least because of the scale of the endeavour required and uncertainties concerning unintended consequences. The aim of this roundtable is to assess whether geoengineering could be a technically and politically viable component of a global strategy to combat climate change.

Dr Masahiro Sugiyama is an Associate Professor at the Policy Alternatives Research Institute (PARI), the University of Tokyo. He holds a Ph.D. in climate science and a master's degree in technology and policy, both from MIT. Prior to joining PARI, he was a researcher at the Socio-Economic Research Center, the Central Research Institute of the Electric Power Industry. He joined PARI in April 2014
Dr Andrew Lenton is a Principal Research Scientist in CSIRO’s Climate Science Centre. A focus of his research is exploring climate solutions (geoengineering) using earth system models, having been closely involved in negative emissions (carbon dioxide removal) research over many years. Amongst other national and international roles, he currently co-leads the international Carbon Dioxide Removal Model Intercomparison Project (CDRMIP), exploring the potential and implications of negative emissions for climate, and sits on the GESAMP UN Working Group on Marine Geoengineering (WG41). He has more than 15 years research experience and is an author of the 5th and 6th IPCC Assessment Reports. At present he leads the ocean biogeochemical research modelling team at CSIRO and acts an advisor on Geoengineering and Climate.
Professor John C Moore is a Research Professor at the Key State Laboratory of Earth Surface Processes and Resource Ecology, Beijing Normal University, and Research Professor at University of Lapland, Finland. In the Geoengineering project his main activities are leading the whole programme and group 2 activity on Earth System Model simulations of climate engineering. Particular aspects of interest include land surface albedo modification schemes; low dimensional dynamics of the climate system; ocean heat transport and sea level; and extreme events such as downscaling for tropical cyclones and their economic impacts.
Mr Arunabha Ghosh is a public policy professional, adviser, author, columnist, and institution builder. As the founder-CEO of the Council on Energy, Environment and Water, since 2010, he has led CEEW to the top ranks as one of South Asia's leading policy research climate think-tanks in 2016. He has been actively involved in the design of the International Solar Alliance since inception. He conceptualised and is founding board member of the Clean Energy Access Network (CLEAN). With experience in 44 countries, he previously worked at Princeton, Oxford, UNDP (New York), and WTO (Geneva). In 2018, the UN Secretary-General nominated him to the UN's Committee for Development Policy. In 2018, the Government of India appointed him as a member of the Environment Pollution (Prevention & Control) Authority for the National Capital Region.

Professor Anthony (Tony) D Owen is Principal Fellow and Head of Energy Economics at the Energy Studies Institute (ESI), National University of Singapore. Prior to joining the ESI, Tony was a Professor at the University College London (UCL) School of Energy and Resources, Adelaide, Australia, where he held the Santos Chair in Energy Resources. He has a PhD in Econometrics from the University of Kent (UK) and has held visiting appointments at the Universities of British Columbia, Colorado, Leeds, and Exeter, the Organisation for Economic Cooperation and Development (Paris), the UK Department of Energy (Harwell), and the International Energy Agency (Paris). He is a Past President (2004) of the International Association for Energy Economics. Tony was made an Emeritus Professor of UCL in 2013.
