Research for the AASHTO Standing Committee on the Environment. Task 65. Synthesis of Greenhouse Gas Emission Inventory Methodologies for State Transportation Departments

Climate change is potentially the single greatest environmental challenge of this century. The first step to managing this challenge for all organizations (including DOTs) is to gain an understanding of the greenhouse gases emitted by the organization by preparing a greenhouse gas (GHG) emissions inventory. Understanding its GHG emissions profile allows an organization to: (1) develop strategies to manage, and where practical, reduce GHG emissions; (2) consider future options for mitigation and participation in offset programs, sequestration activities, and climate registries; (3) prepare for, and ultimately comply with, regulatory requirements; and (4) performance over time. The purpose of this document is to provide DOTs with assistance on how to collect, assemble, quantify, and report their GHG emissions, for a variety of reasons, including future mandatory reporting requirements where applicable. There are some aspects of DOT operations for which activity data required to quantify GHG emissions will likely be readily available or easy to gather, such as energy consumption data associated with the operation of commercial and institutional buildings and fleet operations. There are other more unique aspects of DOT operations that may prove more difficult to gather and disaggregate appropriate data for, including the energy consumption of street lighting, stoplights, and other small but numerous sites across an entire state.
