A 2012 report from the European Commission states that, unlike the United States, "Shale gas production will not make Europe self-sufficient in natural gas. The best case scenario for shale gas development in Europe is one in which declining conventional production can be replaced and import dependence maintained at a level of around 60%." There is a divergence of opinion among the Weimar Triangle countries with regard to shale gas development. France has introduced a ban, because of the risks connected to the chemicals used in the hydraulic fracturing process, while Germany has suspended operations awaiting further environmental assessments.
