The EU executive launched a green paper on 27 March, setting out Europe's energy and climate aims for 2030, with Energy Commissioner Günther Oettinger taking a favourable position on shale gas.
"I am in favour of producing shale gas, particularly for safety reasons, and to reduce gas prices," he said. "In the United States, which is a big producer of shale gas, the price of gas is four times less than in Europe."
Shale gas has triggered an industrial revival in the United States, which the International Energy Agency expects to become almost self-sufficient in oil and gas by 2035.
But crippling production costs, exploration closures, and government-level environmental concerns have seen the industry’s expansion in Europe waver.
EU climate chief circumspect on shale
Climate Commissioner Connie Hedegaard has adopted a less favourable tone on shale gas, believing its extraction in Europe bears little comparison with the United States.
“We do not expect that it will be so easy in Europe: geological conditions are different, and so are environmental rules and the activity of soils,” she told reporters at the launch of the Commission green paper last month.
But Anne Glover, the chief scientific adviser to Commission President José Manuel Barroso, contradicted this view and gave a scientific green light to shale.
Speaking at a debate on science and policy-making in Brussels on 9 April, she said: “As with all energy production, there will be risks involved whether that is wind or coal power,” Glover told the audience at the debate, organised by the European Policy Centre, a think tank.
“We should not go into a denial phase. From my point of view the evidence will allow us to go ahead [with shale production]. But in terms of extraction and production there are non-scientific issues to be debated,” Glover said.
Europe 'in the denial phase'
António Fernando Correia de Campos, the Portuguese MEP who chairs the Parliament’s science and technology options assessment panel, also endorsed shale during the debate. Although he said he was not speaking on behalf of any parliamentary group or committee, Correia de Campos said Europe was “in the denial phase” on shale gas.
He said it was clear that within five years Europe would be importing shale gas from the US because it cost a quarter to a fifth of current European gas imports. “We are basing our opinion on the denial paradigm, which is one step behind the precautionary principle,” Correia de Campos said.
Member states remain divided on their approach to shale. Last October, British Chancellor George Osborne announced potential tax breaks for domestic shale. The same month Poland declared its push for the gas, saying it would invest some €12.5 million to develop exploration by 2020.
But large-scale production has proved difficult, with European governments and major energy companies recently suspending or halting exploration, and France has imposed a moratorium on shale gas drilling.
Meanwhile doubts remain amongst campaigners about the safety of shale extraction.
"Several peer-reviewed studies have shown that [extracion] operations and production activities significantly increase the cancer risks for communities living less than half a mile from drilling sites,” Antoine Simon, extractive industries campaigner at Friends of the Earth Europe, told EurActiv.
