Environment - Energy

How does WSDOT evaluate Energy?

WSDOT prepares and reviews energy and climate change studies for transportation projects.  More information on WSDOT's work on climate change and reducing greenhouse gas emissions is available at our main sustainable transportation page.

Our Guidance for Project-Level Greenhouse Gas Evaluations under NEPA and SEPA (383 kb) describes how WSDOT addresses greenhouse gas emissions and climate change in our environmental documentation. The February 2013 update separated greenhouse gas analysis from discussions about adaptation to climate change, which is now available on our adapting to a changing climate page. 

Note: this guidance is updated regularly.  

For more information, please contact Jim Laughlin.

How does WSDOT analyze energy?

WSDOT evaluates the energy, primarily fuel, used during project construction and operations.  Energy information should be included in EIS documentation as a chapter for most projects. A full energy analysis should only be included for "mega" and/or multi-modal projects, like the SR520 Bridge Replacement, where there is specific public interest in energy use. 

Information on preparing energy analyses is in the Energy Chapter of the WSDOT Environmental Procedures Manual.  WSDOT also uses an Energy Checklist (pdf 55 kb) for review of energy studies that can also help with project scoping. 

If you are working on a WSDOT project and need an energy study, please submit a completed Task Request Form to Jim Laughlin.
