Lancashire Wildlife Trust has asked for answers from companies involved in fracking in the county before more work goes ahead.
The division of the trust, which also represents Manchester and North Merseyside, has raised concerns about the plans for hydraulic fracturing to extract gas and oil from shale at depths of between 2,000 to 10,000 feet.
Planning permission has been given for exploratory operations on six sites on the Fylde and two in West Lancashire.
Concerns have been raised at sites close to Grange Road, Singleton, Peel Road, Westby, and Banks Enclosed Marsh, over ecology and effects on river estuaries.
The trust’s chief executive Anne Selby said: “We are here to protect nature, but our purpose also includes sustainability and adapting to climate change.
“We have concerns at a local level with regards to the impact of fracking, but we are also joining forces with the other 46 Wildlife Trusts to ensure the Government does not stray from renewable energy plans.
“We must not lose sight of aims to progress our energy sources into a more sustainable future.
“Shale gas is a non-renewable energy source. It may be billed as cleaner than coal, but it is carbon and will contribute to CO2 emission.”
The trust has sent a list of questions to companies involved in fracking in the region, including Cuadrilla, iGas and Dart.
Last week Cuadrilla pulled out of one of its potential fracking sites in Lancashire.
The company said it would not seek consent to frack for gas at Anna’s Road in St Annes and would restore the site to its previous condition, following “technical constraints related to wintering birds”.
Lancashire Wildlife Trust (LWT) believes the development and operation of the extraction process should not cause any damage to areas such as local wildlife sites or SSSIs (Sites of Special Scientific Interest).
It also has concerns about the impact of the process on water quality in water courses and the disposal of the water used to extract the gas, and said it would monitor official regulatory processes.
Mrs Selby said: “The trust will be pressing Government and Cuadrilla, iGAS and Dart hard over these issues and will expect a clear response on how they will handle these.
“Should the challenges and concerns for environmental damage be overcome, the trust would also like to see a proportion of the taxes and revenue generated from such extraction invested in energy reduction, renewable and natural means of capturing carbon such as restoring peat bogs.”
Meetings have already taken place between Cuadrilla staff and LWT members.
A spokesman for Cuadrilla said: “We’re committed to working with the community and are keen to take on board the views of local people and organisations as we continue to assess the full potential of Lancashire’s Bowland shale.
“As part of this process we’re already speaking to the Lancashire Wildlife Trust and were delighted to welcome them on a site visit to Elswick on Wednesday, where we had the opportunity to address their questions.
“More than 200 people and organisations, including the Lancashire Wildlife Trust, have already provided input into Arup’s environmental assessment work.
“We look forward to continuing these important discussions.”
