Will Marre, CEO of REALeadership Alliance and author of "Save the World and Still Be Home For Dinner," based his rankings on a company's strategic integration of sustainability and "positive human impact."
The companies are Gap, Kohl’s, Staples, REI, Wal-Mart, Target, Best Buy, Nike, Lowes, and Apple, according to a press release.
Apple, the last company on the list, does not fit the typical mold of a retailer, although it does have retail outlets. Marre said the reason he included Apple is because "the actual products they create are sustainability in action."
Kohl's is a more conventional choice, as it holds the No. 1 retail spot on the EPA's Green Power purchasers list.
