Case Study of an Energy and Environmental Inventory for a Municipal Heavy Duty Diesel Equipment Fleet

As the nation moves towards more sustainable practices in all industry segments, heavy duty diesel (HDD) equipment owners are encouraged to utilize strategies that make their fleets “cleaner and greener.” In order to determine whether or not these strategies are effective, HDD fleet managers need a methodology that not only establishes a baseline of current fuel use and emissions quantities but also quantifies the energy and environmental impacts of the various alternatives under consideration. This paper presents a practice-ready methodology for developing an energy (diesel fuel) and environmental (pollutant emissions) inventory for nonroad HDD equipment. The methodology is demonstrated via a case study for a fleet of 47 HDD equipment items owned by a local municipal government. The approach to calculating the fuel use and emissions of each equipment unit is based on equations employed by the Environmental Protection Agency NONROAD model; however, actual equipment attribute data from the case study fleet is used in order to make the results specific to the case study fleet. The resulting energy and emissions inventory presents the total fuel use and emissions of nitrogen oxides, particulate matter, hydrocarbons, carbon monoxide, and carbon dioxide for each item of equipment, as well as totals for each equipment subgroup and the overall fleet. Recommendations for using and improving the energy and environmental inventory are provided.
