The U.S. Department of Energy (DOE) Industrial Efficiency and Decarbonization Office and Change Chemistry (formerly the Green Chemistry & Commerce Council, GC3) co-hosted the Sustainable Chemistry in RD&D [research, development, and demonstration] to Transform the Chemicals Sector Roundtable on March 7, 2023. The event brought together about 50 participants—from industry, national laboratories, small businesses, startups, nonprofits, and government—to gather input on how to effectively leverage sustainable chemistry to advance industrial decarbonization, industrial efficiency, and environmental justice goals. This report is a summary of the views expressed by individual participants during the roundtable; it is not intended to represent DOE’s views or programmatic priorities.

This provides a summary of draft modeling efforts undertaken by the U.S. Department of Energy (DOE) Industrial Efficiency and Decarbonization Office (IEDO) as an extension and expansion of the 2022 Industrial Decarbonization Roadmap. IEDO is providing these draft modeling results to support stakeholder engagement and inform office- and department wide strategy and decision making. Section 1 provides an overview of the context for this analysis and modeling as well as information on the decarbonization pillars characterized and the models themselves. Section 2 presents modeling results of one net-zero emissions pathway each for six industrial subsectors: cement, chemicals, food and beverage, iron and steel, petroleum refining, and pulp and paper. It is important to note that these pathways are just one example and there is no single pathway for any single industrial subsector. Competition across different possible pathways will be essential to industrial decarbonization success. Section 3 provides an overview of the “rest of industry” subsectors and a high-level overview of net-zero barriers, challenges, pathways, and technologies. IEDO will continue to consider net-zero pathways and modeling for these rest of industry subsectors. Additional details will be made available in the future on the IEDO website.
