In some cases, the potential influence is vast. Consumer Reports of the United States, for example, has 5 million subscribers and its television reports reach many millions more. The magazine included a survey that offered subscribers an opportunity to rate their own lifestyles. Next it will show how conservation pays by tracking the bills of a household in which energy-efficient light bulbs and solar water heaters have been installed. Widespread scepticism about the accuracy of marketing claims is a significant factor reducing the take-up of environmentally friendly alternatives.
Some consumer groups regard checking manufacturers' claims as part of their information function.
In Nordic countries, and in India and Indonesia, for example, consumer groups are active on eco-labelling boards to ensure that consumer rights and environmental concerns are taken into account. One of the consumer rights is the right to a healthy environment. At the same time, consumers have a responsibility to protect the environment and to use their considerable economic and political power to bring about the changes needed to redirect society onto a more environmentally responsible path. Consumer groups should not merely participate, but should lead society towards that more sustainable future.
