Ethical consumerism (alternatively called ethical consumption, ethical purchasing, moral purchasing, ethical sourcing, ethical shopping or green consumerism) is a type of consumer activism that is based on the concept of dollar voting. It is practiced through 'positive buying' in that ethical products are favoured, or 'moral boycott', that is negative purchasing and company-based purchasing.
The term "ethical consumer", now used generically, was first popularised by the UK magazine Ethical Consumer, first published in 1989.Ethical Consumer magazine's key innovation was to produce 'ratings tables', inspired by the criteria-based approach of the then emerging ethical investment movement. Ethical Consumer's ratings tables awarded companies negative marks (and from 2005 overall scores) across a range of ethical and environmental categories such as 'animal rights', 'human rights' and 'pollution and toxics', empowering consumers to make ethically informed consumption choices and providing campaigners with reliable information on corporate behaviour. Such criteria-based ethical and environmental ratings have subsequently become commonplace both in providing consumer information and in business-to-business corporate social responsibility and sustainability ratings such as those provided by Innovest, Calvert Foundation, Domini, IRRC, TIAA–CREF and KLD Analytics. Today, Bloomberg and Reuters provide "environmental, social and governance" ratings direct to the financial data screens of hundreds of thousands of stock market traders. The not-for-profit Ethical Consumer Research Association continues to publish Ethical Consumer and its associated website, which provides free access to ethical ratings tables.
In Unequal Freedoms: The Global Market As An Ethical System (1998), John McMurtry argues that no purchasing decision exists that does not itself imply some moral choice, and that there is no purchasing that is not ultimately moral in nature. This mirrors older arguments, especially by the Anabaptists, e.g. Mennonites, Amish, that one must accept all personal moral and spiritual liability of all harms done at any distance in space or time to anyone by one's own choices. It is often suggested that Judeo-Christian scriptures further direct followers towards practising good stewardship of the Earth, under an obligation to a God who is believed to have created the planet for us to share with other creatures. A similar argument presented from a secular humanist point of view is that it is simply better for human beings to acknowledge that the planet supports life only because of a delicate balance of many different factors.
