Kimberly-Clark. Here's a look at the EPA's top nine list. The rankings are done based on renewable energy use and conservation. Doesn't measure whether they get leather from Brazilian cattle or recycled paper shipped in from China. I'm glad to see one of my favorite beer makers is on this list. Note that most of the top greenies are in the western U.S. EPA also lists the top purchasers of green power among American corps. LIst includes a number of tech firms: Intel, Cisco, Motorola, Sony, Dell, Sprint, Lockheed, AMD. In some cases it's a specific facility of the corporation.
