In an “Emerging Europe” blog entry at the Wall Street Journal, Marynia Kruk reports on Poland-based natural gas firm PGNiG SA’s statements regarding European regulation of shale gas extraction. The company insists that individual countries should decide on whether to institute moratoriums on the extraction of shale gas, not the Brussels-based European Parliament. As in the United State, hydraulic fracturing (fracking) of rock has triggered the debate, and, in some countries, bans.
