This report was developed in part to share our long-standing commitment, dedication, and achievements regarding sustainability. Based on stakeholder feedback concerning the most beneficial methods to disclose certain related information, we have provided metrics using the Global Reporting Initiative (GRI) and the Sustainability Accounting Standards Board’s (SASB) Iron & Steel Producers Standard. GRI provides a framework for organizations to report on the impact and management of economic, social, and environmental matters. SASB provides a framework to report on industry-specific sustainability topics that are deemed to be material. Additionally, in order to make our information more accessible, we have provided a GRI and SASB cross-reference index, and it is available on our website at steeldynamics.com under Sustainability.
