Nucor aimed to lead the steel industry in sustainability by providing customers, investors, and stakeholders with transparent, credible data on the environmental impact of its steel products. As demand for lower embodied carbon materials grew and green building standards became more stringent, Nucor needed to demonstrate that its operations and products complied with evolving requirements for carbon disclosure, life cycle assessment, and verified sustainability claims.
The complexity lay in gathering accurate emissions data across multiple steel mills and product lines, standardizing Environmental Product Declarations (EPDs) for different steel grades, and ensuring that all reporting met global standards such as LEED v4, ISO 14040/44, and other third-party frameworks. To maintain trust and competitiveness, Nucor also had to manage internal processes, data integrity, and third-party verifications, all while ensuring timely delivery to meet market and regulatory deadlines.
