German court bans Lufthansa from using misleading sustainable aviation fuel claims in ads, highlighting rising regulatory scrutiny of greenwashing in aviation

The Cologne Higher Regional Court prohibited Lufthansa from using certain claims about sustainable aviation fuel in its advertising, finding the statements misleading. The ruling underscores heightened regulatory enforcement of greenwashing rules in the aviation sector, raising legal and reputational risks for airlines making environmental claims. Who is involved: Lufthansa, the Cologne Higher Regional Court (OLG Köln), German advertising regulators under the Unfair Competition Act, and consumers.. Likely next: Lufthansa must cease the prohibited statements and may submit revised advertising for clearance; further scrutiny from competition authorities or courts is possible.. The Cologne Higher Regional Court ruled that specific Lufthansa advertisements about sustainable aviation fuel (SAF) misled consumers and ordered the airline to stop those statements. The decision applies Germany’s Unfair Competition Act, which prohibits deceptive environmental claims, and aligns with broader EU efforts to curb greenwashing. As a result, Lufthansa faces potential fines, must revise its marketing, and the airline sector may see increased compliance costs and tighter scrutiny of sustainability messaging. Sectors affected: Airline industry Aviation fuel sector Regulatory implications: German Unfair Competition Act (UWG) §5 prohibits misleading environmental claims; the court’s decision applies this law to SAF advertising. EU Unfair Commercial Practices Directive (2005/29/EC) requires clear, substantiated green claims, reinforcing the national ruling.
