WSDOT is combating climate change by working to reduce agency and transportation sector greenhouse gas emissions. One way to accomplish that is to adopt sustainable, low carbon materials and construction methods as standard practice. To do that, it is investigating the use of Environmental Product Declarations and life cycle assessment in construction project procurement (in a concurrent project), and it will develop a sustainable procurement strategy for construction and materials. To assist WSDOT in that goal, UW researchers are working to develop a viable carbon reduction strategy, a greenhouse gas (GHG) inventory procedure, methods for including sustainability in contract documents and specifications, and a method for tracking sustainability commitments throughout the construction process. This procurement strategy will support WSDOT in purchasing materials and contracting for services that have less negative or more positive effects on the environment and human health.
