Tim Kruger is a James Martin Fellow at the Oxford Geoengineering Programme (OGP), an initiative of the Oxford Martin School at the University of Oxford. He coordinates the activities of the OGP, which is seeking to assess the social, technical, environmental and ethical issues associated with all proposed geoengineering techniques. He has investigated in detail one potential geoengineering technique, that of adding alkalinity to the ocean as a way of enhancing its capacity to act as a carbon sink and to counteract the effects of ocean acidification.
Tim is on the Advisory Board of the UK's Integrated Assessment of Geoengineering Proposals and of the EU's European Union Transdisciplinary Assessment of Climate Engineering. He was also one of the co-authors of "The Oxford Principles" - a set of draft principles for the conduct of geoengineering research that were endorsed by the UK Government in their response to the House of Commons Science and Technology Committee's Report on "The Regulation of Geoengineering".
