McDonalds vp of social corporate responsibility, Bob Langert, noted on the company's blog site their top ten global green initiatives in 2007. Among them includes installing dry urinals in their Swiss restaurants to cut water consumption; converting used frying oil into biodiesel in McDonalds UK; green restaurant constructions in France, Brazil and the US; reduced food packaging; and implementing sustainable supply chain for its food ingredients such as coffee, soybeans and fish.
According to Langert:
I referred to these as "green laboratories" because we are always testing, learning, and exploring the scalability of green initiatives so that we can continuously improve our environmental performance.
In his Reuters interview, Langert emphasized that customers comes first when it comes to making green decisions. If they don't like their new green Macs, then back to the drawing board!
