Riley Duren is Chief Executive Officer and founder of Carbon Mapper, a non-profit organization focused on delivering precise and transparent methane and carbon dioxide data to guide mitigation action. Additionally, he is a Research Scientist at the University of Arizona. Previously he served as a lab Fellow and Chief Systems Engineer for JPL’s Earth Science Directorate spanning multiple NASA science and technology programs. Since 2010 he has led research efforts to develop and test multi-scale monitoring systems that support mitigation of greenhouse gas emissions including serving as principal investigator for multiple projects funded by NASA, NIST and California agencies. One offshoot of that research is the Carbon Mapper public-private partnership to launch a constellation of satellites designed to monitor 90% of the world’s high emission methane and carbon dioxide point sources at facility scale.
