It will take more than promises and glossy marketing campaigns to convince consumers that Wal-Mart is green, a recent study has found.

The largest retailer on earth finds itself the subject of Environmental Leader’s latest study on green marketing. Despite Wal-Mart’s massive green marketing campaign over the last year, consumers still don’t consider the retailer a sustainable company, explaining:

Brands that have spent significant marketing dollars communicating green initiatives such as Wal-Mart and GE are not connecting.

Environmental Leader’s report focuses specifically on the effectiveness of green marketing campaigns, but it implies a much larger truth: consumers aren’t buying Wal-Mart’s greenwashing. The chart above (click here for a larger version) explains that in the minds of socially-conscious shoppers, social responsibility goes far beyond Wal-Mart’s current definition. Employee treatment, community connection and supply chain practices are equally important as environmental issues. But Wal-Mart has a track record of trouble in each of these categories, leading conscientious consumers to rightfully distrust the company’s green overtures.

Wal-Mart’s habit of making cosmetic changes instead of systematic improvements to its business practices aren’t fooling any shoppers. If Wal-Mart wants its green message to stick, it needs to address its sustainability problems from the ground up. Corporate transparency, employee friendliness, and fair, sustainable product sourcing aren’t just footnotes to an advertising campaign - they’re necessary parts of the modern responsible corporation. Wal-Mart would be better served to use the millions it currently spends on marketing to make holistic changes to its business model.
