Methods for State DOTs to Reduce Greenhouse Gas Emissions from the Transportation Sector

The objective of this project is to provide guidance on currently available, practical, and innovative methods for state DOTs to assess and advance transportation-related GHG reduction strategies in planning and programming. The guidance will support state DOTs' efforts to integrate GHG emissions considerations into their decision-making processes as well as methods appropriate for collaborative activities undertaken with partners to shape outcomes outside the purview of a state DOT. The guidance should be relevant for the evolving role of state DOTs and be adaptable to a changing regulatory environment at the state and federal levels, while also considering uncertainties related to future travel behavior, the future vehicle fleet, and other demographic and technological changes. The project will also broaden the practice of addressing GHG emissions in state DOT decision making through targeted implementation activities to support state DOT adoption or updating of GHG emissions reduction methods.
