Court Bars Lufthansa from Repeating Environmental Claim
A German appeals court (Oberlandesgericht Köln) has prohibited Lufthansa from repeating certain environmental claims in its advertising. The court ruled against the airline following a lawsuit by the Deutsche Umwelthilfe (DUH), stopping Lufthansa's promise that customers can "directly reduce" flight-related CO2 emissions during booking by paying an extra charge for sustainable aviation fuel (SAF). Judges found consumers were not given precise information about when the bio-based kerosene was actually used. The decision targets the specific marketing statement and reflects legal scrutiny of greenwashing claims in advertising.
Court ruling restricts advertiser environmental claims and reinforces legal scrutiny of greenwashing, affecting marketing compliance and message practices for brands operating in Germany and potentially influencing wider EU advertising standards.

Environmental NGO Wins Case Against Netto Discount
The Deutsche Umwelthilfe (DUH) reported a legal victory against Netto Marken-Discount over a yoghurt advertisement. The dispute concerns sustainability claims in Netto's marketing — an image caption in the article notes Netto promoted yoghurt with the slogan “Gutes Futter – aus umweltschonendem Anbau.” The DUH continues to pursue cases against companies it says make misleading environmental claims. The report was published by Lebensmittelzeitung (Deutscher Fachverlag) on 2026-08-13 and authored by Ruth Herberg. The ruling is part of a broader pattern of NGO enforcement of green-marketing claims, increasing legal scrutiny on retailer advertising practices.

Austrian EmpCo Rules Ban Unsubstantiated Green Claims
Starting September 27, 2026, stricter rules on environmental advertising take effect in Austria via the UWG amendment implementing EU Directive 2024/825 (EmpCo). The law adds several forms of green marketing to the 'black list' of unfair practices, meaning unsubstantiated claims like 'climate neutral' or 'eco-friendly' become prohibited without proof of outstanding environmental performance. The use of carbon offsets for product-related climate claims is banned. Sustainability seals must be based on recognized certification systems. The law also restricts misleading statements on product durability and repairability. The Green Claims Directive remains stalled, leaving gaps in the verification framework. Companies face the task of auditing their marketing claims and ensuring compliance.
