EXTINCTION REBELLION unveiled today its plan to “paralyse” movement of oil supplies in Britain.

The group aims to mobilise hundreds of thousands of protesters in an unprecedented blockade of oil refineries which it hopes will “stop the harm at the source.”

The ambitious plan will be put into effect on April 9 with the intention of causing “maximum nonviolent disruption” of fossil fuel industries.

An Extinction Rebellion statement said: “We are calling on protest groups, NGOs and individuals to join us and take a stand to stop fossil fuels once and for all. Now is the time, this is the moment.”

The plan follows last week’s United Nations Intergovernmental Panel on Climate Change (IPCC) report which warned of the increasing and irreversible effects of climate change.

Organisations working with Extinction Rebellion include Just Stop Oil and Plan B.

Tim Crosland, of Plan B, said: “Our addiction to fossil fuels must end immediately if there’s to be any hope left of tackling the climate crisis. 

“There can be no denying this anymore. Last week’s devastating IPCC report is just the latest in a series of increasingly desperate warnings from scientists.

“We know what is happening, we know what needs to be done and we know those in power are failing us.

Extinction Rebellion co-founder Clare Farrell said: “Oil refineries are symbolic of continued extraction and profit for a small group of very wealthy companies at the expense of everyone else.

“We need to decarbonise and to do so as fast as possible.”

In a letter to the government, Extinction Rebellion said: “Every day the government fails to act makes our common future more bleak, our prospects more terrifying.”

Exact locations of the planned protests are yet to be made public.
