NYT: THE FACTS ON FRACKING

In sum, the experience of fracking in Pennsylvania has led to industry practices that mitigate the effect of drilling and fracking on the local environment.

And while the natural gas produced by fracking does add greenhouse gases to the atmosphere through leakage during gas extraction and carbon dioxide release during burning, it in fact holds a significant environmental advantage over coal mining. Shale gas emits half the carbon dioxide per unit of energy as does coal, and coal burning also emits metals such as mercury into the atmosphere that eventually settle back into our soils and waters.

Europe is currently increasing its reliance on coal while discouraging or banning fracking. If we are going to get our energy from hydrocarbons, blocking fracking while relying on coal looks like a bad trade-off for the environment.
