International Consolidated Airlines scores 23/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.
That places International Consolidated Airlines joint 721st of 790 companies scored, and joint 15th of 23 in Airlines / Aviation.
IAG's emissions are rising in absolute terms while it claims progress via intensity metrics. Scope 3 disclosure is narrow and underweighted. The airline has no validated science-based targets, relies heavily on carbon offsets, and actively lobbies against EU climate policy—its CEO chairs IATA, which InfluenceMap rates as systematically obstructive.
