In the last several years, the Western part of the United States has faced severe drought conditions with a lack of rain in states such as New Mexico, Arizona, and California. In these communities, Walmart collects rainwater in underground tanks and saves it to water the store’s landscaping. In addition, Walmart takes advantage of other opportunities to conserve water. It has installed high-efficiency urinals that reduce water use by 87% compared to the conventional 1-gallon-per-flush urinals throughout all new stores. These high-efficiency toilets use 20% less water compared to allowable EPA standards of up to 1.6 gallons per flush. Based on this information, it seems that Walmart is engaging in a. environmental marketing. b. sustainable marketing. c. eco-marketing. d. green marketing
