Greenwashing is a form of advertising or marketing strategy where tactics are deceptively used to persuade the public that an organisation/company's products, aims, and policies are environmentally friendly. (For example: Volkswagen cheating the pollution emissions tests on its vehicles and advertising its environmentally friendly cars, Coca-Cola portraying itself as sustainable but is the biggest polluter of plastic in the world, and H&M’s false advertising of using "sustainable" materials in their clothing.)
