This paper tests a methodology proposed by a U.S. government inter-agency working group for calculating a facility-level U.S. national average greenhouse gas emissions intensity for a selected traded good. The testing of the method relies on publicly available data from the U.S. government supplemented by for purchase data. To draw practical insights, a pilot product is selected for this initial test (cold-rolled stainless steel with width less than 600mm). Lessons learned based on the results of testing the method with this product include: 1) the level of product specificity chosen should consider the emissions and production data availability for the product, particularly with respect to the product’s supply chain, production pathways, and any co-products from its production, and 2) more granular, nonpublic micro-data collected by the U.S. government include additional relevant details that may address gaps in publicly available data and hold promise towards successfully applying the U.S. government proposed method. This paper is intended to provide a preliminary assessment of data availability, potential pathways for calculating scope 1 and scope 2 emissions from industrial facilities, and related challenges and potential remedies. As such, it draws its findings based on testing one product. Extension of any findings from this paper should be corroborated with results from testing additional products. Findings reported in this paper are preliminary and meant to inform potential future work to assess data needs and availability for determining facility-level greenhouse gas emissions intensity of a traded good. This paper is the first of an envisioned series reporting on methods for bench-marking facility-level greenhouse gas emissions intensities of U.S. products.
