The document discusses various tools that can be used to promote ethical behavior in governance. It describes codes or oaths, ethics audits, and human resources management practices as tools to integrate ethics into organizational culture. While no single tool is sufficient, the document advocates using multiple tools together, including codes, audits, staff meetings, ethical awareness committees, and incorporating ethics into hiring, evaluations, training, and having ethics counselors. Leadership and a combination of these tools is needed to effectively promote integrity.
