Summary To meet growing energy demand & stabilize atmospheric CO 2 levels - need to diversify fuel pool and introduce >30% drop in zero carbon fuels The LanzaTech process can capture non-food, waste carbon to produce low cost alcohols Alcohols produced via the LanzaTech process are an excellent substrate for conversion to drop-in hydrocarbon fuels Commercial alcohol production rates on raw industrial waste gases has been demonstrated at scale Compelling volumes of waste gases world wide have potential to make significant impact on the fuel pool Strong business development pipeline will accelerate commercialization process Collaborating with leading conversion partners, industry agencies, and certification bodies to develop sustainable, low cost, integrated hydrocarbon fuels processes from non-food sources
