This document summarizes a presentation about applying business integrity given by John Howarth of Jacobs Engineering LLC. It discusses how the construction and engineering sector faces significant challenges with corruption. Corruption damages economies, projects and careers while inhibiting investment. While laws alone cannot prevent corruption, companies can take collective action by setting clear expectations, robust governance, and zero tolerance policies. The presentation advocates for conducting business ethically and transparently, ensuring partners exhibit the same behaviors, and providing a fair process to stamp out unethical influences in decision making. Maintaining integrity throughout long supply chains is challenging.
