In September 2022, an aircraft campaign measured methane emissions from all 57 Angolan offshore oil and gas facilities. Total CH₄ emissions were 16.9 ± 5.3 t h⁻¹, dominated by older, shallow-water platforms. Emissions were lower than inventories but 2 times larger than operator reports. Trace gas data suggest venting and fugitives as main CH₄ sources. The carbon intensity was 3.4 ± 0.8 g CO₂ eq MJ⁻¹, with older platforms CH₄-dominated and newer deep-water sites CO₂-dominated.
