In the United States and other industrialized countries, many consumers are making “green” choices in their behavior and purchases that reflect concern for the environment.

In some cases, these choices carry a price tag, such as paying more for organically grown food or for clothing made from organic cotton. Consumers are also motivated to make green purchases that save money. For example, after gas prices topped $4/gallon in 2008, sales of gas guzzling SUVs dropped, and sales of more fuel-efficient cars, such as hybrids, increased. Consumers often consider their utility bill when they choose energy-efficient appliances and electrical equipment.
