An influential panel of MPs has called for fracking to be banned in areas of natural beauty.
The cross-party Environmental Audit Committee (EAC) said it would seek an amendment to the Infrastructure Bill to outlaw digging for shale gas in certain places.
The government has committed to backing fracking but fears remain over safety and the environment.
EAC chair Joan Walley said: “Ultimately fracking cannot be compatible with our long-term commitments to cut climate changing emissions unless full-scale carbon capture and storage technology is rolled out rapidly, which currently looks unlikely.
“There are also huge uncertainties around the impact that fracking could have on water supplies, air quality and public health.
“We cannot allow Britain’s national parks and areas of outstanding natural beauty to be developed into oil and gas fields… there should be an outright ban on fracking in such special sites.”
The Infrastructure Bill will have its third reading in the House of Commons today.
Walley added: “The government is trying to rush through changes to the trespass laws that would allow companies to frack under people’s homes without permission.
“This is profoundly undemocratic and Parliament should protect the rights of citizens by throwing these changes out when they are debated later today.”
