natural gas leading to reduction in US emissions – a case for technology investment instead of policy?

Interesting observations over at yale360 on falling US emissions:

It seems to be a unique situation that we are observing here..and I’m not sure technology investment without policy is a good model to follow..

I wonder how much of the reduction in emission is coming from ethanol production?  They don’t really connect reduction in emissions as being due to increased use of natural gas and I question this causative link..

I think there are still questions about the CO2 emissions of natural gas vs coal, especially when natural gas is obtained via fracking (as evidenced by many of my previous posts about articles trying to estimate the GHG impact of fracked gas).

Plus, these falling emissions are probably just a result of the recession and will increase as the economy recovers (we are already seeing record wordwide emissions in 2010).

  1. The fact that it took 30 years to develop competitive technologies to extract gas from shale puts things in perspective.
