Research Agency: Cambridge Systematics, Inc.
Principal Investigator: Mr. Chris Porter
Effective Date: 7/27/2021
Completion Date: 1/26/2024

NCHRP WebResource 3 is a guide for state departments of transportation (DOTs) and partner agencies that provides resources and approaches for addressing greenhouse gas (GHG) emissions and climate change effects in transportation environmental reviews. The WebResource:

  • Provides tools, methods, and resources to support consideration of GHG emissions and climate change effects in transportation project environmental reviews pursuant to the National Environmental Policy Act (NEPA) and to state environmental review requirements.
  • Describes how plan-level or programmatic environmental reviews and assessments can inform project-level environmental reviews.
  • Provides tools, methods, and resources for considering equity as related to GHG emissions and climate change effects.

Associated with the WebResource is NCHRP Web-Only Document 400: Considering Greenhouse Gas Emissions and Climate Change in Environmental Reviews: Conduct of Research Report, which provides a summary of the research that went into developing the guide, as well as a fact sheet that summarizes the project’s essential findings and an implementation memo that identifies implementation pathways for the project.
