“…The Buy Clean Colorado Act provides CDOT 2.5 years to collect EPD data, and then allows CDOT to use the collected data and nationally recognized EPD databases to develop GWP limits. There have been some studies that provide recommendations for GWP limits for construction materials (Lewis et al 2021, Carlisle et al 2022, Mattinzioli et al 2022; however, literature of the subject of limit setting is sparse.…”

The use of EPDs in procurement of construction materials has been of increasing interest to government agencies, and adoption in the United States has been driven in part by “Buy Clean” legislation. Buy Clean encompasses green procurement policies that promote the purchase of construction materials and products with lower environmental impacts, considering the life-cycle impacts associated with those materials. Most EPDs for transportation infrastructure construction materials are “cradle-to-gate”, or representative of the material production stage of a product and not the entire life cycle; however, these EPDs can allow meaningful quantitative comparisons of environmental and sustainability indicators and serve as a mechanism for measuring improvements in environmental impacts during the production of materials. This paper describes how cradle-to-gate EPDs are used, presents a case study of initial implementation of an EPD policy by the Colorado Department of Transportation (CDOT), and provides recommendations to address some of the challenges that agencies and stakeholders can face when developing or participating in new EPD programs. It is desired that the recommendations and case study presented in this paper will help provide pathways to agencies for the successful enactment of Buy Clean policies and enable mitigation of actual or perceived barriers to program implementation.
