Spill prevention Performance Preventing hydrocarbon leaks and spills is a key priority for ADNOC. Spills can pose operational, safety and environmental risks, making prevention, preparedness and effective response essential to maintaining safe and responsible operations. ADNOC has established policies and procedures designed to mitigate the risk of spills, support containment and implement rapid response measures in the event of an incident. In 2024, the number of hydrocarbon spill incidents increased. However, the total volume of oil spilled was lower than in previous years. All incidents were below 10 barrels, and no spills occurred near environmentally sensitive areas. Our waste management, emergency response, and oil spill response standards guide our approach to spill prevention, control and mitigation across operations31.
