Fossielvrij NL, Reclame Fossielvrij, and ClientEarth have teamed up and sent a joint legal letter to a group of 71 airlines operating out of Schiphol airport, the Netherlands. The letter warns the airlines on the legal boundaries surrounding sustainability claims in aviation, following a ruling by the Amsterdam District Court against KLM. The environmental groups are urging the airlines to revise their advertising strategies to comply with the clarified legal standards.
