Nike says its goal is to blend a minimum of 5 percent organic cotton into all of its cotton-containing apparel materials by 2010, while steadily expanding its offering of 100 percent certified-organic cotton products.
In 2008, the big-box retailer purchased 12 million pounds of cotton from farmers who were transitioning from conventional to organic farming to help boost the supply of certified-organic cotton available on the market. No matter what the company's intentions, be they financial, altruistic, or a little of both, any move Wal-Mart makes is significant by virtue of its massive supply chain and sheer ubiquity—factors that would play no small role in pushing us past the tipping point.
Isetan has some organic cotton items for father's day, but they obviously need to do more to promote pesticide-free, non-GMO cotton. Their annual report from 2005 (pdf) made some promises, I'm hoping they are committed. As for Uniqlo, they seem to be trying; a pity they had no vision to make it into the global top 10.
