AISI releases GHG emissions guidelines for steel

The American Iron and Steel Institute (AISI) has released recommended steel industry greenhouse gas (GHG) emissions calculation guidelines to provide consistent and comprehensive data across the industry on GHG emissions from steel production, with a focus on product-level disclosures and corporate-level reporting. The proposed guidelines are the result of months-long collaboration with key American steel producers and Institute staff.

The American steel industry’s leadership on reducing emissions is well-known, but there are often disparate sources and avenues for calculating and reporting. Our industry wants to remain transparent, accurate and outspoken in our advocacy on decarbonization-related activities—and these guidelines can be an important tool to achieve those goals.

AISI staff researched and compiled information on how external initiatives and programs are addressing scoping and methodology for GHG emissions which has resulted in this initial set of recommendations. A consistent set of data will help ensure policymakers and other stakeholders employ the most accurate information in their decision-making.

—Kevin Dempsey, AISI president and CEO

Highlights of the recommendations for GHG emissions calculation are:

  • Calculations should include a comprehensive “cradle-to-gate” (all processing steps required to manufacture a defined product) scope analogous to Scope 1, 2, and upstream raw materials, energy, and transportation Scope 3 emissions;

  • Calculation of direct (Scope 1) emissions should use the EPA GHG Reporting Rule methodology for US-based facilities, with the addition of those facilities below the 25,000 metric tons CO2e per year reporting threshold;

  • Emissions from the purchase of electricity should be based on local electricity grid factors and reflect renewable energy instruments in specified instances; and

  • Emissions should be calculated at the product level for trade, procurement, and environmental product declaration purposes, while a company-wide basis should be used for corporate reporting.

Dempsey concluded that the recommendations are not intended to be a formal industry standard, but a means to inform efforts underway by American and international steel producers and others working to develop GHG emissions calculation methodologies.
