The rating system might not hit store shelves for a few years, but Wal-Mart plans to start its first phase of the project soon by asking suppliers to answer a questionnaire to determine each product's level of eco-friendliness. Factors such as water use in the manufacturing process and recycling potential will count toward a product's final rating.
I've heard criticism that the cost of some products may rise when suppliers decide to redesign them to get a better eco-rating, which industry consultant Burt P. Flichinger said can increase a product's cost up to 3 percent.
My concern is the greenwashing that will ensue. Companies will be scrambling to get a competitive edge by having a more eco-looking product. How does Wal-Mart plan to verify the story-telling from suppliers? Unless the government standardizes the process and creates specific penalties for greenwashing, I'm not sure that the rating system will mean much.
