Recent green public procurement (GPP) initiatives in the U.S.A. rely on the use of the construction materials EPDs. EPD programs, however, were initiated by the material manufacturers, motivated by their interest to use EPDs as communication tools, improve production efficiency, and extend outreach. The goal of GPP initiatives is to produce the environmental improvements, however, it is unclear if the current EPD programs and GPP mechanisms can reliably support that goal. This study investigates the use of EPDs in GPP to ensure the environmental improvement of materials (use of EPDs as a procurement aid) and pavements (use of EPDs as a data source). The objective of this study was to identify prerequisites, challenges, implementation frameworks that include stakeholders and ensure environmental benefits with EPDs. A review of to-date EPD programs for pavement materials, communication with stakeholders, and analysis of pavement life cycle assessment (LCA) were performed. The use of EPDs that ensures environmental improvements of materials is contingent on EPD consistency and PCR prescriptiveness. EPDs can be suitable as data sources in pavement LCA due to their availability, transparency, and because they facilitate collaboration and improvements throughout the supply chain. However, it is noteworthy that if EPDs are used in that capacity, harmonization of all relevant PCRs and the establishment of aligned pavement LCA framework are necessary for reliable environmental improvements. The availability of public background data can support both EPD development and GPP efforts, by providing transparency, inclusivity, and low costs of LCA. Greater automation, systems for data transfer and management, and increased stakeholder collaboration can also support GPP in a way that ensures environmental improvements of pavement materials and infrastructure.

在美利坚合众国(美国)使用路面材料的环境产品声明(EPD)以确保减少环境影响

美国最近的绿色公共采购(GPP)计划依赖于建筑材料EPD的使用。然而,EPD计划是由材料制造商发起的,其动机是希望将EPD用作沟通工具,提高生产效率并扩大范围。GPP计划的目标是改善环境,但是目前的EPD程序和GPP机制是否可以可靠地支持该目标尚不清楚。这项研究调查了GPP中EPD的使用,以确保改善材料(使用EPD作为采购辅助工具)和人行道(使用EPD作为数据源)的环境改善。这项研究的目的是确定包括利益相关者在内的先决条件,挑战和实施框架,并通过EPD确保环境效益。审查了最新的EPD路面材料计划,与利益相关者的沟通以及对路面生命周期评估(LCA)的分析。确保材料环境改善的EPD的使用取决于EPD的一致性和PCR规定性。EPD由于其可用性,透明性以及促进整个供应链中的协作和改进而适合用作路面LCA中的数据源。但是,值得注意的是,如果以这种能力使用EPD,则必须对所有相关PCR进行协调,并建立对齐的路面LCA框架,以实现可靠的环境改善。通过提供透明性,包容性和低成本的LCA,公共背景数据的可用性可以支持EPD开发和GPP努力。更高的自动化程度
