GREEN TRANSPARENCY

Here's a nice trend: big companies proactively disclosing their greenhouse gas emissions and pushing their suppliers to do the same: "Carbon Copy." It reminds me of that device that is being marketed nowadays, that glows different intensities to denote the amount of electricity that an appliance is using, to help call attention to energy waste and encourage users to unplug or reduce: when it's in your face, you tend to notice and from there figure out ways to minimize. Kudos for Walmart, Procter & Gamble, and others for getting ahead of the curve on this one. Would that we all, in our much smaller ways, be similarly accountable for our energy consumption.
