Abstract: Significant reductions in atmospheric emissions of volatile organic compounds (VOC) and greenhouse gases (such as SF$-6$/) are being actively pursued by industrialized countries around the world. GasVue is a relatively new technology having the potential to locate the large leak sources responsible for the majority of these atmospheric emissions many times faster than is currently feasible. The rapid repair of these large leak sources offers the significant emission reductions sought by both industry and regulatory agencies. An overview of the GasVue development history and a brief description of the technology are presented. However, the primary purpose of this paper is to summarize technology evaluations and field test results conducted since 1997. Field test results involving SF$-6$/ leaks in electrical substations, natural gas leaks from underground distribution systems, and VOC leaks from petroleum processing units are described and discussed. Plans for future field tests and improvements to the technology are outlined. !15
