The European Union should not close the door to new developments such as shale gas at an early stage, the EU climate chief said, although she is not inclined to back a moratorium on it.

"I would not be inclined to a moratorium on the basis of what I've heard so far" on the technology, Connie Hedegaard, EU commissioner for Climate Action, said during a press conference Friday. "We cannot afford at a very early stage to say no" to a technology, she added.

Hedegaard also explained that shale gas will likely not have the same strong development in
Europe that it's had in other parts of the world.

The resource, and the technology associated with it, is becoming a matter of division among EU countries, with
Poland --largely in favor of it--and France --broadly opposing it--on the extremes.
