ADNOC set an upstream methane intensity target of below 0.15% by 2025, exceeding the industry near-zero methane benchmark of 0.2%. In 2025, we achieved an upstream methane intensity of 0.05%, well below our own target and among the lowest upstream methane intensity performance in the industry. This reflects the strength of ADNOC’s methane management approach and underpins our near-zero methane ambition by 2030. Total upstream methane emissions in 2025 increased by 10% compared to 2024, reflecting higher operational throughput and the addition of new LNG shipping combustion sources reported in line with guidance from the United Nations Environment Programme’s Oil & Gas Methane Partnership (OGMP). Despite this increase in absolute terms, methane intensity remained strong and well below ADNOC’s 0.15% upstream target, reflecting the effectiveness of ADNOC’s measurement and mitigation approach in maintaining performance as the portfolio grows. ADNOC reports methane emissions in accordance with the OGMP 2.0 framework, achieving Gold Reporting Status for the second consecutive year in 2025 and progressing toward site-level reporting across material assets. The measurement approach covers source-level measurements across most methane-emitting sources spanning flaring, fugitives, venting and combustion, supported by advanced detection technologies including optical gas imaging, high-flow sampling, drone surveys and satellite monitoring. Data quality is continuously improved through reconciliation of bottom- up inventories with independent measurement campaigns, ensuring mitigation efforts are targeted and verifiable. ADNOC’s methane reduction strategy focuses on eliminating emissions at source through design, operational practice and infrastructure investment. Key measures include zero routine venting across upstream operations with extensive deployment of flare gas recovery systems and vapor recovery units to reduce methane emissions from venting and flaring, leak detection and repair programs with rapid repair protocols and recurring monitoring cycles, electrification of process equipment, improvement in flare combustion efficiency and replacement of high-emitting components with low-emission valves, seals and pneumatic systems. ADNOC continues to build on its direct measurement and monitoring capabilities, advancing material assets toward OGMP Level 5 reporting and embedding methane considerations into asset design and planning.

Since 2022, ADNOC’s clean power agreement with Emirates Water and Electricity Company has enabled a progressive shift from onsite self-generation to lower-carbon grid electricity. By 2025, nearly all of ADNOC’s grid electricity was supplied by nuclear and solar sources. Project Lightning is one of the most significant contributors to ADNOC’s decarbonization roadmap and 2030 intensity target. The largest electrification investment in ADNOC’s medium-term decarbonization program, the project is enabling ADNOC’s offshore facilities to transition from onsite gas-turbine generation to clean power from the grid, via a first-of-its-kind utility-scale subsea high-voltage direct current (HVDC) transmission system. In 2024, the project focused on large-scale construction and offshore interface preparation. In 2025, approximately 950 km of subsea cabling was completed, alongside critical island interface works and electrical infrastructure readiness. In 2026, we plan to advance into pre-commissioning readiness activities including metering compliance, grid-code alignment, system calibration and HVDC maintenance planning. Once operational, Project Lightning is expected to eliminate at least 5 million tCO₂e of emissions annually representing an important step toward our 2030 intensity target.
