At Berkeley Lab, stewardship means taking responsibility for our mission, our people, the environment and our resources. One way we put that into practice is through the stewardship principle: We Earn Trust. Trust is built through our everyday actions and the standards we uphold in our work.
Building and maintaining trust requires a consistent commitment to excellence, integrity, safety, transparency, reliability, and accountability. Whether working with the public, the scientific community, stakeholders, or our colleagues, the way we communicate, collaborate, and take responsibility for our work shapes the confidence others have in our organization.
These same values are at the core of a strong Contractor Assurance System (CAS). CAS supports continuous improvement, operational excellence, and accountability by encouraging clear communication, safe work practices, and transparency. When we consistently demonstrate these behaviors, trust becomes something we actively earn and maintain.
