Green MP Caroline Lucas was among those arrested at a sit-in aimed at halting plans to drill for shale gas in a West Sussex village.
As campaigners in Balcombe begin a five-day camp in protest at fracking, supporter Tisha Brown tells ITV News why it's such a crucial issue.
The chief executive of Cuadrilla Resources, Francis Egan, told ITV News the company "will complete our approved work" at its Balcombe site.
Residents and business owners near fracking sites have described why they have joined the Greenpeace legal challenge:
– Eve McNamara, a resident who lives near a site in Lancashire
I'm joining the legal block because fracking will be an absolute disaster for Lancashire. I hope sense will prevail and the industry will leave, so the North West can concentrate on renewable energy.
– Andrew Pemberton, a Lancashire dairy farmer
I'm supplying milk to 3,000 households, and if for any reason my water became contaminated, my business would be ruined and my livelihood destroyed, as well as the livelihoods of the 16 families who work for me. Fracking is dangerous and short-sighted. We should be keeping this gas in the ground.
– Karen Ditchfield, a resident near the Singleton site
My husband and I are joining the legal block because we're worried and frustrated about what's going on. No one has asked us if they can drill under our home and land. But this is not just about my life, it is my children's lives, and what we're leaving for people for years to come. More effort should be put into safer and longer-term energy sources.
The UK Onshore Operators Group said in a statement:
This announcement by Greenpeace is extremely misleading. Operators in this country are abiding by the law, which states that activities at depths of over a mile under the ground do not impact landowners. However, in line with the law, operators will inform all landowners in a very clear and transparent manner.
Underground working is hardly something that is employed by just the oil and gas industry but includes pipelines, fibre optics, geothermal energy and transport tunnelling to name but a few.
Greenpeace is arguing that plans to drill horizontally under people's homes is unlwaful if they don't have permission from the owners.
Greenpeace Senior Campaigner Anna Jones said: “Under English law, if you own land, your rights extend to all the ground beneath it. That means if someone drills under your home without permission it is trespass.”
“To avoid being liable for trespass, drillers would need landowners’ permission. And this case is about people explicitly declaring they do not give that permission. This will make it extremely difficult for companies to move ahead with any horizontal drilling plans.”
Greenpeace has launched a legal challenge to fracking in England to halt what it calls “reckless and presumptuous” plans for shale gas extraction across the country.
It made the announcement at a joint press conference with people whose homes are in the firing line of potential fracking sites, including residents from Balcombe in Sussex.
Greenpeace expects thousands of people to join the legal block, creating a patchwork of no-go areas for the fracking industry across the country.
A police officer from the force overseeing major anti-fracking protests has received "management advice" after labelling activists as "scum" on Twitter.
The comment was picked up by a member of the public, who tweeted, "#balcombe @sussex_police should your officers really be calling protesters 'scum' on twitter? I suggest you issue some guidance ASAP."
The force said in a statement: "Sussex Police has received a report of a personal Twitter account belonging to a Sussex officer, which is abusive to protesters at Balcombe.
"We have worked hard to engage with everyone involved in and affected by the activities surrounding the drilling operation at Balcombe and no matter who authors them, such comments are unhelpful and not acceptable."
Energy firm Cuadrilla is making a new application for its drilling site in Sussex at Balcombe, as its current one runs out at the end of the month. It is not withdrawing from site.
But like the current application they are not asking for permission to frack on the site yet - it is test drilling.
The row over fracking in the UK started in Lancashire, when a small earthquake in Blackpool was linked to the controversial practice.
Fracking in that area stopped for technical reasons. Some local communities are keen that it does not return, whilst politicians want proper regulation to ensure its safety.
Science Editor Lawrence McGinty brought together local residents and experts to discuss the issue, which many communities across the UK are currently facing.
Anti-fracking protesters will maintain a presence outside an exploratory drilling site following two days of direct action against the energy company carrying out the work.
The "mass civil disobedience" saw police officers arrest more than 30 people at the Cuadrilla site near Balcombe, West Sussex, including Green MP Caroline Lucas.
Nine people have been charged and will appear in court next month, four were cautioned and released, while the rest are due to answer bail at the end of August.
Sussex MP Francis Maude has released a statement following the protests outside his office yesterday.
He said: "I'm sorry that the genuine concerns and peaceful protests of Balcombe residents have been drowned out by illegal direct action by organisations who have no direct interest in the locality. "
– Francis Maude, Local MP for Sussex
My constituents in Balcombe are entitled to have their voices heard and their concerns addressed by the regulators. The company also have a right to carry out an activity which has been subjected to the full rigour of regulatory scrutiny. As for the demonstration at Gough House, this was one of the most pointless exercises I have come across. The only effect was to cause distress and hassle to our hardworking dedicated team, and to waste even more police time and precious resources."
Anti-fracking protesters were surrounded by police today as they linked arms in front of a lorry making its way to the gates of the Cuadrilla site in Balcombe, West Sussex.
The protest has so far remained peaceful, despite an earlier arrest of a woman.
