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.
International Consolidated Airlines scores 23/100 (Significant gaps) on SINK's independent climate assessment, scored from public data only. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified October 2026.
