Environmental Product Declarations

Update to the Environmental Product Declarations for Fabricated Structural Steel

Projects seeking certification under the LEED program, other green rating systems and standards, or state legislation (such as California Assembly Bill 262) require the submission of Environmental Product Declarations (EPDs) for the materials used on the project.  AISC is working with our mill members to develop industry average EPDs for structural steel produced in the United States. In addition to quantifying the impacts of the mill processes, it is also required that we quantify the industry average per ton environmental impacts of the fabrication process.

To be able to do this, it is necessary that we collect data from AISC member fabricators regarding the environmental impacts of fabrication.  Once this data is collected, combined and analyzed you will be provided access to the industry average EPD for fabricated structural steel for use as a submittal on projects.  According to the current rules of the LEED program, only AISC members participating in the development of the EPD will be able to submit the EPD on LEED registered projects. Failure to participate in this survey may impact your ability to bid on and provide structural steel for those projects.

To participate in the update to the industry average EPD, please perform the following:

1. Watch the below webinar.
2. Read the instruction letter, outlining the need for the update and data collection.
3. Submit your April 2019 data, utilizing this spreadsheet.
4. AISC will vet the April 2019 data and provide comments/suggestions, if needed.
5. Submit your April 2019 to March 2020 data, utilizing the spreadsheet.

Please submit all data, as well as any questions regarding the EPD update and data collection, to Luke Johnson (johnson@aisc.org) at AISC.

All survey responses will be kept completely confidential and not be used for any purpose other than the development of the EPD.  All results will be reported on an industry average basis. Individual responses will only be viewed by designated AISC staff members directly working on this project and our consultant, Thinkstep. 


Current Environmental Product Declarations for Fabricated Structural Steel (Expires March 31, 2021)

The structural steel industry actively supports the transparent reporting of environmental impacts associated with construction products.  Many rating systems (LEED V4), standards (ASHRAE 189.1) and green building codes (IgCC) require the submission of environmental product declarations (EPDs) for products delivered to the project site. These EPDs rely on the results of life-cycle assessments to provide information on a number of environmental impacts related to the manufacture of the product, including global warming potential, ozone depletion, acidification, eutrophication and ozone creation.

AISC has currently developed industry average EPDs for three products:

These EPDs, which cover the product life cycle from cradle to fabricator gate, satisfy the submission requirements for programs such as LEED and Green Globes. Based on the rules spelled out in the ISO standards relative to EPDs, they can only be used by firms who participated in the development of the EPD through membership in the producing organization.

For that reason, an EPD  can only be submitted for project credit by firms that were AISC members at the time of its development or who have subsequently joined AISC and submitted environmental impact data relative to their shop. They cannot be submitted for project credit by a fabricator who does not meet these qualifications. In addition, these EPDs can only be used for mill material produced in the United States.  For hot-rolled structural sections the EPD can only be used for domestic material produced by:

  • Nucor Corporation
  • Gerdau
  • Steel Dynamics, Inc.
  • Bayou Steel

For steel plate, the EPD can only be used for domestic material produced by:

  • Nucor Corporation
  • Arcelor-Mittal
  • SSAB North America

For HSS, the EPD can only be used for material produced by:

  • Atlas Tube, Inc.
  • Hannibal Industries, Inc.
  • Indepencence Tube Corporation
  • Maruichi American Corporation
  • Maruichi Leavitt Pipe & Tube, LLC
  • Maruichi Oregon Steel Tube (MOST)
  • Searing Industries
  • Southland Tube, Inc.
  • Vest, Inc.

AISC member fabricators that are authorized to submit these EPDs in fulfillment of LEED project requirements include:
