Through their work with the National Center for Smart Growth at the University of Maryland (UMD), the Prince George’s County- Department of Parks and Recreation commissioned this report from the university’s Partnership for Action Learning in Sustainability (PALS). PALS works with local jurisdictions throughout Maryland to identify projects and problems that can be taught through university courses where students focus on developing innovative, research-based solutions. The Prince Georges County Department of Parks and Recreation was seeking to reduce carbon emissions by 50% from 2019 levels within Division of Maintenance and Development. This report centers obtaining research on the consumption metric for the vehicles (ie., mpg) and equipment (ie., gal/hr) present within the inventory and use these values in combination with the equipment and vehicle use metric (ie., miles, hrs) to determine CO2 emissions based on type of fuel required to operate the equipment or vehicle for the Prince Georges County Department of Parks and Recreation maintenance division .
