Lee  Scott seems to think they can. Some excerpts from his remarks to the gathering  of suppliers as well as executives from his own company:
    
Sustainability is here to stay. It is not a fad, it is not a    marketing ploy. . . . It is in fact a part of what all of us are going to be    doing with our businesses from here on out. It is not about higher margins and    higher prices. It is about the elimination of waste. It is about making our    businesses more effective. It is about transferring those benefits on to the    consumer. And it is about taking chemicals and things we know aren't good for    the environment and finding alternatives to those chemicals so we make    products safer. 
   I think for Wal-Mart one    of the key roles for sustainability is it is going to cause us to have better    products. Because we're going to be thinking about the quality in those    products: what is the defective rate  . . . what are the life-cycle costs    of that product . . . . Ultimately my view is that because of sustainability,    we also will be dealing with the best companies. Let me talk about sourcing    from someone who is willing to compromise on the environment -- maybe destroy    waste in an inappropriate way, or use chemicals that they shouldn't. What in    the world would make Wal-Mart think that the person who is willing to    compromise the environment, knowingly, wouldn't also be willing to compromise    on quality to meet a price point? . . . 
   My belief is that we're    going to find that sustainability and all of these social context issues are    all related and all end up showing up in the quality of the products. And that    as we use sustainability as a driving force, we will have better suppliers . .    . and it will enhance the reputation that we have as a  company.
 High-minded words, to be sure. And they will likely rankle Wal-Mart's many  detractors, for whom the words "Wal-Mart" and "sustainability," used together,  are simply discordant. The doubters are not irrational. For years, Wal-Mart has  been an aggressive, sometimes arrogant, leviathan, seemingly out of touch with  progressive social and environmental ideas and ideals. In its single-minded  pursuit for growth and dominance, it played rough -- with competitors,  communities, suppliers, politicians, and anyone who got in its way, notably (or  especially) activists. How can this sudden embrace of sustainability be anything  other than a cynical ploy?
 I'm pretty sure that it's not. In recent months, Wal-Mart has put itself out  there in ways that few other companies have done. It is spreading the green  gospel to its 1.3 million employees, teaching them how to live greener lives. It  is inviting activists into its offices, and commanding suppliers to meet new,  green goals, and parading its CEO in front of audiences and the press to talk  the sustainability talk.
 To the extent the cynics are right, it's that Wal-Mart's mission is to sell  more stuff to more people in the pursuit of profitability and growth, an  arguably unsustainable proposition. And that's a problem.
 But along the way, the behemoth from Bentonville stands to move hundreds,  perhaps thousands of suppliers toward a more sustainable path, and help to fuel  consumer demand for things organic, nontoxic, and efficient, among other  attributes. And, perhaps, engender everyday environmental habits among the  citizenry in ways that even the most committed environmental activists have  failed to do.
 As Scott put it last week:
    We have simply started.    We make no claims of being a green company. We're not saying we're better than    anyone, we're not saying we're doing it right. What we're saying is that we    recognize an opportunity to make a difference in this world, make a difference    for our customers, for our shareholders, for our associates, and it is    worthwhile to do.
 It's a messy affair, this sustainability thing. And Wal-Mart has made more  than its share of the mess. But maybe, just maybe, that same company, in its  dogged pursuit of productivity and profits, can create more than its share of  the solution, too.
