I was very struck by Brad Plummer’s blog at wapo.st/19SIJ1C (Washington Post), about the ability of the US to hit its greenhouse gas emission targets (cutting GHGs by 17% from 2005 levels) by 2020. It is well worth reading.
Plummer shows that hitting the targets is not out of the question, but that the engine of economic growth creates constant upward pressure on emissions.
My takeaway is that, at least in the USA, there is no evidence that a decoupling of industrial growth from GHG emissions is on the horizon. We have to hope that technology and innovation will produce the breakthroughs needed to make the decoupling a reality.
