The fashion industry is notorious for its environmental impact, yet many brands claim to be "sustainable." In a recent case, online fashion giant Zalando was caught in the greenwashing spotlight. After an investigation by the European Commission and national authorities, Zalando agreed to remove misleading sustainability flags and icons from its platform, acknowledging the need for clear and specific information about environmental benefits. This case, however, is not an isolated incident. It reflects a growing trend of consumer protection authorities cracking down on greenwashing practices.
