The nation of shopkeepers looks like it’s leading in new ways. Eco-Advantage reports that both Marks & Spencer and Tesco have announced major environmentally conscious programs. Andrew Winston, one of the writers of Eco-Advantage, says the companies’ goals are “aggressive, creative, comprehensive, and instantly establish a new best practice”. The programs aren’t just vague aspirations, both companies have committed real money and have created timely, tough targets. Let’s hope the relatively dozy US retail sector wakes up.
