To track its greenhouse gas (GHG) emissions reduction progress, Arlington County developed community-wide GHG inventories for calendar years 2007, 2012, 2016, and, most recently, 2023. A GHG inventory provides a snapshot of annual emissions generated by activities within a particular area, such as Arlington County. The County’s community-wide GHG emissions inventories track progress toward meeting GHG reduction goals, identify the largest sources of emissions, and serve as the basis for directing and prioritizing climate actions.
