Why you should listen
While it is essential that we reduce global carbon emissions, that isn't going to be enough to avoid dangerous climate change. Research into proposed geoengineering techniques could prove vital in the fight to protect our planet. At the Oxford Geoengineering Programme, Tim Kruger aims to assess the range of proposed geoengineering techniques to determine which, if any, could be both technically feasible and benign environmentally, socially and ethically.
Kruger, a James Martin Fellow at the University of Oxford, is a co-author of "The Oxford Principles," a draft code of conduct for geoengineering research. It calls for geoengineering to be regulated as a public good, for public participation in decision-making and for disclosure of research and open publication of results.
In addition to his work at Oxford, Kruger is also CEO of Origen Power, which is developing a process that uses natural gas to generate electricity in a way that removes carbon dioxide from the atmosphere.
