Technical sessions took place over five days. Among the plenary speakers was S. Forbes Pearson, Ph.D., a visiting professor at the University of Strathclyde, Glasgow, Scotland. Another plenary speaker was Elsa Murano, Ph.D., of the U.S. Department of Agriculture.
At ICR, Pearson focused on CO2, characterizing it as a natural refrigerant with no ozone depletion potential or global warming potential. Proponents of CO2 were more aggressively promoting their product at the event. Some 34 technical papers focused on CO2, a quantum leap above the single-digit number of papers on the topic at past conferences.
