Performance We generated 30% more total waste in 2025 than 2024, reflecting expanded operational activity. Over the same period, we diverted more than 17,000 tonnes of waste from disposal.

Our operations are located across desert, coastal and marine environments and have the potential to impact biodiversity and ecosystem services through the nature and scale of our operations. At the same time, ADNOC recognizes opportunities to generate positive biodiversity outcomes through restoration, habitat enhancement and nature-based solutions, contributing to ecosystem resilience and supporting national biodiversity priorities. Our biodiversity framework and strategy are aligned with the UAE National Biodiversity Strategy, evolving Abu Dhabi biodiversity policies and long-term environmental goals. We apply a systematic monitoring and risk-based approach to biodiversity assessments across the project lifecycle. With a focus on identifying potential impacts, we implement mitigation measures in line with the mitigation hierarchy which prioritizes avoidance, minimization, restoration and, where necessary, offsetting. This is supported by EIA mitigation measures and ongoing monitoring. The proportion of protected areas overlapping with ADNOC’s concession areas increased from 25% to 36% in 2025, following an Emiri decree that expanded protected areas in Abu Dhabi. These areas include habitats that support species of conservation importance, including those listed on the UAE National Red List, and therefore require enhanced management. ADNOC conducts EIAs when undertaking new projects or significant operational modifications to identify potential biodiversity impacts at an early stage. These include ecological surveys, which help establish a baseline understanding of local species and habitats, identify and assess potential impacts, and prioritize mitigation measures. ADNOC prioritizes biodiversity management at sites located near ecologically sensitive habitats, including coastal zones, offshore islands and desert habitats. 18 All concessions are owned by ADNOC and located in Abu Dhabi, United Arab Emirates. The type of operations in these concessions is extractive and production. All concessions contain portions of protected areas. Environmental protected areas are managed by the EAD. 19 ADNOC implements the Biodiversity Assessment Standard- HSE-EN-ST06 to assess the biodiversity within ADNOC concession areas. 20 Includes the following fields: Bu Hasa, Bida Al Qemzan, Bab, Jumaylah, Al Nouf, Rumaitha, Shanayel, Asab, Mender and Qusahwira.
