Are Corporate Sustainability Efforts Working?

Nine years ago, Walmart announced its landmark initiative to reduce waste and cut greenhouse gas emissions. But today its emissions are 14 percent higher. That sounds like the initiative was a failure, right? Maybe not. In this week's podcast, the Gang sits down with corporate sustainability expert Andrew Winston to chat about how to judge the success of greening efforts at big companies. Later in the show, we'll discuss the threat of extreme weather to energy infrastructure, and we'll look at the meaning behind the latest wind construction boom. The Energy Gang is produced by Greentechmedia.com. The show features weekly discussion between energy futurist Jigar Shah, energy policy expert Katherine Hamilton and Greentech Media Editor Stephen Lacey.
