摘 要：Reducing the environmental impact of facilities and operations has become an important function for many organizations. In many cases, such as utility and fuel use, reducing these impacts can also be coupled to financial savings. The Kansas Department of Transportation (KDOT) has determined that conducting an energy and CO2 audit of its building and vehicle fleets will aid in assessing KDOT energy use, prepare for any future regulations regarding CO2 emissions, and help identify areas for increased savings through reduced use of commercial resources (primarily energy and fuel). Phase 1 of this project established baseline carbon and energy data from three major sources: the total energy embodied in the construction, operation and repair of KDOT-owned buildings, the total energy embodied in KDOT use of utilities (electricity,  water and natural gas) and the energy expended in the operation of KDOT’s vehicle fleet and other associated equipment.
