You need to do more research on Wal-Marts worldwide "green" effort. They claim it actually saves them a ton of money, and hey, if everyone "feels" it is saving the world, even better. It's P.R.
Not only do they recycle almost all their "in store" refuse, at least they have recycle trashcans in the breakrooms, they also recycle all the cardboard, and various other things deemed "environmentally unfriendly." They score all their vendors with an environmental impact card and if they don't reduce the packaging material, and make it more environmentally friendly, they lose shelving space. Look it up, there are tons of articles on their efforts. They are even working with Dow Corning to try and recycle plasma screen glass.
They got rid of the "recycle stations" because of liability issues that came up in other states. They get sued for everything. I hear nowadays they are pretty much run by the legal dept.
Then look at their new and remodeled stores, (In some cases, old stores too.) they are the leader in green technology and innovation in commercial grocery stores.
The use of skylights to help bring in natural light, thereby cutting down on energy consumption. Most other grocery stores have ceiling grid.
They are testing LED lighting in some stores for sales floor lighting.
They put solar panels on some stores, and windmills. Look at this article from 2006 that talks about the one they built in McKinney. sacramento.bizjournals.com/sacramento/st...06/03/20/story8.html
They utilize state of the art equipment to control everything from the dimmable fluorescent sales floor lights to the refrigeration, in order to have the most energy efficient buildings in the industry.
The new mechanical refrigeration equipment they are putting out decreases the use of "dangerous" refrigerants by %90, also reducing the load on the building for the coolers and freezers. This system also uses hardly any copper and mostly pvc inside the store.
They are basically doing everything the environmentalist think they should be doing (and saving themselves a ton of money in energy costs) in order to maintain peace and harmony on those issues. I haven't heard any negative news on these issues. No "Too big of a carbon footprint" garbage.
It goes on and on and on and on.
