Transparency

We Strive for Transparency in Our Reporting and Disclosures

BY ANALYZING SIGNIFICANT TOPICS ON AN ONGOING BASIS, WE WORK TO MEET OUR STAKEHOLDERS' EXPECTATIONS

Our stakeholders' information needs are growing – and we are committed to publicly reporting on ESG topics on an annual basis to communicate our impacts, performance and the ways we are generating long-term value. We use our annual Sustainability Disclosure and Performance Summary, as well as other voluntary reporting initiatives, to convey information in a way that is balanced, comparable, and decision-useful.

Since our first sustainability report in 2010, transparency has been the foundation for improved governance and performance in the areas that matter to us and our diverse stakeholders. These activities promote deep and ongoing engagement with our internal and external stakeholders; help us gain a clearer understanding of our impacts in the context of the environments in which we operate; drive accountability for our impacts; define our strategy; and prioritize actions for improvement.

We participate in numerous voluntary reporting initiatives. Our annual sustainability disclosure is prepared in accordance with GRI Standards: Core option and aligned to many of the Sustainability Accounting Standards Board (SASB) metrics for Metals & Mining and Chemicals Industries. Report content is defined by issues identified through significance studies, the results of which we analyze on an ongoing basis.
