Robert K. Dixon of The World Bank Group, Dixon was Team Leader for Climate Change and Chemicals (2008 to 2015), overseeing a multibillion-dollar portfolio of energy, environment, public health, infrastructure, and transportation projects in developing and transition countries. Dixon has been a delegate to intergovernmental negotiating committees and subsidiary bodies of the United Nations Framework Convention on Climate Change (1992 to present), Montreal Protocol on Substances that Deplete the Ozone Layer (1989 to present), Minamata Convention on Mercury (2009 to 2015), the Asia-Pacific Partnership on Clean Development and Climate (2006 to 2011), the Stockholm Convention on Persistent Organic Pollutants (2004 to 2015), and
Montreal Protocol and HCFCs. Thus, in 2009, a study calculated that a fast phasedown of high-GWP HFCs could potentially prevent the equivalent of up to 8.8 Gt CO2-eq "per year" in emissions by 2050. A proposed phasedown of HFCs was hence projected to avoid up to 0.5C of warming by 2100 under the high-HFC growth scenario, and up to 0.35C under the low-HFC growth scenario. Recognizing the opportunity presented for fast and effective phasing down of HFCs through the Montreal Protocol, starting in 2009 the Federated States of Micronesia proposed an amendment to phase down high-GWP HFCs, with the U.S., Canada, and
