This briefing highlights the public debate around fracking; the interests of Canadian oil and gas companies in shale gas reserves in Europe; and the impacts an investment protection clause in the proposed CETA could have on governments’ ability to regulate or ban fracking. It examines the case study of the company Lone Pine Resources Inc. versus Canada, which, using a similar clause is challenging a fracking moratorium and suing the Canadian government for compensation, and warns this could be the state of things to come in Europe. It recommends that the investor-state dispute settlement mechanism should not be included in CETA.
