Tackling greenwashing is an issue where human rights, consumer rights and climate goals align. Companies use greenwashing to convince people to buy products that are not always as environmentally friendly as they claim to be. They mislead consumers and harm the environment. This report shows how a human rights approach can combat greenwashing. It is based on consultations with experts in 10 Member States. The report identifies gaps in existing laws and enforcement. It includes case studies of consumers seeking remedies for misleading environmental claims. The EU and Member States should enforce rules that make it harder for companies to make misleading environmental claims. They should strengthen rules that make it easier for consumers to prove that companies are greenwashing. Consumer and environmental organisations already hold governments and business to account. Governments should make it easier to use collective action for the protection of consumer rights and the environment.
