Performance ADNOC’s SOx emissions were 12% lower in 2025 than in 2024, primarily because of a reduction in sour gas flaring activities and improvements in operational efficiency. NOx and PM emissions remained broadly in line with 2024 levels. NMVOCs increased by 7%, mainly due to higher tanker loading operations, while CO emissions rose by 5%, driven by higher power demand and increased fuel demand from the deployment of additional drilling rigs.

These thresholds are supported by targeted pollution control plans and measures intended to meet these thresholds and reduce impact. Such actions may include the following: • Deploying best available engineering controls and technologies, such as dry low NOx combustion systems • Electrifying and enhancing the efficiency of power turbines • Conducting regular leak detection and repair (LDAR) programs to mitigate fugitive emissions • Switching from sour to sweet gas fuel to reduce sulfur dioxide (SO ₂ ) emissions • Recovering waste heat through dedicated energy efficiency projects • Installing vapor recovery compressors and ejectors to reduce flaring in design and upgrading projects • Installing oil treatment units (pre-heaters) to reduce emissions during loading operations • Deploying high efficiency combustors and incinerators during well testing operations to reduce smoke and methane emissions • Installation of VOC vapor recovery systems at fuel retailing stations We have well-defined processes in place to report, investigate and address emissions-related incidents, including conducting root cause analyses and implementing corrective actions to prevent recurrence. ADNOC maintains a comprehensive monitoring ecosystem designed to track, analyze and manage air emissions across its operations, integrating both point source emissions monitoring and ambient air quality monitoring. ADNOC also works closely with the Environment Agency - Abu Dhabi (EAD) to monitor ambient air quality and support broader environmental oversight. Systems are integrated with EAD’s air quality database and ADNOC has contributed to expanding monitoring coverage by providing fixed air quality monitoring stations across Abu Dhabi. To monitor air quality around its facilities, ADNOC operates a network of air quality monitoring stations that continuously track ambient conditions, generating real-time data that feeds into centralized systems. In 2025, ADNOC launched the air quality management system (AQMS), enabling real-time compliance tracking and notification of potential issues. Ambient air quality monitoring ADNOC monitors emissions from stationary combustion sources and operations, through the air emissions monitoring system (AEMS). This centralized framework uses continuous emissions monitoring systems (CEMS) to measure emissions in real time. It also uses predictive emissions monitoring systems (PEMS) to estimate emissions based on operational data and process conditions. As of 2025, 50% of ADNOC’s point emission sources were covered under AEMS, reflecting steady progress in expanding monitoring coverage and strengthening emissions management.
