This article purports to point out the difficulty in determining what is and isn't green. Reminds me of the early days of the recycling craze when we discovered that it took more energy to recycle some materials than it did to make them originally. This happens almost anytime emotion is put before science.
To that end.. while I don't disagree with the author's assertions that calculating total carbon emissions can be complex, I don't buy the underlying premise in the first place. That being, that humans are causing global warming. There's simply no hard evidence of it. In fact, the evidence isn't clear that we're still warming. This administrations emotional instead of science based polices in this regard are detrimental to every American.
