Keith’s recent research has had a particular focus on atmospheric methane, a greenhouse gas whose atmospheric abundance has grown 2.5-fold over the past three centuries. His research has used carbon isotope data to better understand the processes responsible for this growth in abundance. In collaboration with agricultural scientists, he has led ground-breaking research on the measurement of methane emissions by farmed ruminant livestock in New Zealand, most notably applying and developing the so-called ‘SF6 tracer technique’.

Keith has presented papers on greenhouse gas research at more than 30 international conferences as well as in specialist peer-reviewed journals.

Keith has contributed strongly to reports and publications of the IPCC (Intergovernmental Panel on Climate Change). This effort resulted in sharing the 2007 Nobel Peace Prize awarded to IPCC.
