Focus: 2030 Challenge for Products


The embodied energy (and embodied carbon) of building materials has always been important, but as we create more energy-efficient buildings, the proportion of total life cycle energy use and carbon emissions associated with manufacture and transport of the materials going into those buildings becomes more significant. Also, reductions in the embodied carbon emissions of materials have an immediate benefit, while the carbon reductions through reducing the building's energy consumption in operations are accrued over a longer period of time. Reducing the embodied carbon emissions of materials has a very important role to play in slowing global climate change as the goal is to reduce the total quantity of carbon dioxide getting into the atmosphere and do it as quickly as possible.

The 2030 Challenge for Products from Architecture 2030 aims to reduce the embodied carbon (meaning the carbon emissions equivalent) of building products by 50% by 2030. Of the total energy consumption and greenhouse gas emissions in the U.S., 5%–8% results from the manufacture and transport of building products and the construction of buildings.

To meet the 2030 Challenge for Products, industry leaders are working to develop accurate and comparative data on the embodied carbon pf building products. To allow comparison of products against the 2030 goals requires standardization of the process of measuring embodied carbon. Industry groups are now developing product category rules (PCRs) that define how to undertake a life cycle assessment in a consistent fashion and display its results in an Environmental Product Declaration (EPD) for any individual product in a building product category. These EPDs provide comparable information on the life cycle impact of a range of environmental flows from building product life cycles, including but not limited to carbon. While focusing attention on carbon, the Challenge will also aid the development of robust measurement systems that will improve our ability to also assess other health and environmental impacts of building products.

This Information Hub, a partnership of BuildingGreen, Architecture 2030, and Healthy Building Network, is intended to provide design professionals, manufacturers, or other interested parties with the information and resources they need to achieve embodied carbon reduction goals.

Standards and Standard Development

Resources For PCRs

Product Category Rules (PCRs) define what must be included in an Environmental Product Declaration (EPD) for a product, including embodied carbon. The list below identifies resources for finding PCRs and product-specific EPDs. It is our intention to keep this website updated with information on what new PCRs are in development or recently published, and how to find out about PCRs and EPDs that exist today. This is not a screened, vetted, or comprehensive list. We welcome your suggestions for additional, relevant resources to consider.

Completed PCRs including protocols for reporting Embodied Carbon

Architecture 2030 has compiled an aggregated list of PCRs relevant to the building industry. The sites below have aggregated, but not comprehensive, lists of PCRs. Some of these are relevant to the building industry.

Please note that using internationally generated PCRs for U.S. products can leave many judgements outstanding and/or result in significant variation in results based on different assumptions. They are however, an ideal starting point for developing a regionally appropriate PCRs.

Program Operators

These organizations are involved in the development and registration of PCRs and EPDs. Any organization may develop a PCR, however it must be registered by an EPD program operator before it can be used for an EPD, and program operators are often involved in the development process. Each organization is responsible for hosting an updated list of their PCRs and/or EPDs.

LCA Practitioners

A product-specific LCA underlies development of an EPD.
