Internal sustainability teams drive initiatives and workstreams to meet these targets, and we remain committed to aggressively pursuing their attainment through internal rigor, investment and innovation.

Where there is a need for new internal standards or updates to existing ones, working groups comprised of regional and corporate EH&S experts are established. We then develop and communicate the draft to internal stakeholders, soliciting feedback, and considering revisions before the standard is finalized and approved. We have set ambitious internal goals for safety, health, and environmental protection, and we regularly conduct audits to monitor our performance and progress toward these goals.
