Regardless of the size, severity or cause of an event, each ExxonMobil facility and business unit has access to trained responders and resources. Cross-functional teams develop and practice emergency response tactics through incident management teams and emergency support groups around the world. This preparation enables ExxonMobil’s global operations to provide a robust response in emergency situations to help protect the safety of people and the environment. In 2019, we carried out a Regional Response Team exercise in Egypt to demonstrate the readiness to plan and execute real-time field deployments effectively, based on the response actions included in the Egyptian National Oil Spill Contingency Plan. With more than 150 participants representing 27 countries, the five- day exercise strengthened alignment on response objectives between key stakeholders and the Regional Response Team. 18 | Sustainability Report Highlights
