Last week we started to hear the mind-boggling story of a huge corporation that has found that it couldn’t afford not to go green – Walmart. There’s a lot more to this story. What did they learn?

Diane Brandon is joined again this week by Edward Humes, a Pulitzer-Prize winning Journalist and Author of Force of Nature – The Unlikely Story of Walmart’s Green Revolution. This story never ceases to amaze and all businesses need to take a cue from Walmart – if they want to save money and be viable in today’s economy.
