We need energy security. We need sustainable energy. We need to meet our legally binding targets. Fracking will not deliver any of these. But it will deliver greenhouse gases.

It is not logical or sensible to develop fracking at the very moment we have signed up to the Paris agreement on climate change, and announced the end of coal. By the time fracking becomes a significant force – 2030 – Britain must already be very low-carbon.

Last time we voted on this in 2013 we gave conditional approval to fracking. But these conditions have been broken. We were promised that our national areas of exceptional beauty would be protected. We were promised local people would hold sway. We were promised Carbon Capture and Storage to lessen the effects. These conditions have gone. All gone.

We could trust Ed Davey with responsible, regulated fracking. But we cannot trust the Tories. They have shown on every front that environment protection is extremely low priority. They are destroying our renewable industries and being reckless with our economic future.

We need clear green water from the other parties – a clarion message on climate change. Not a fudge and an excuse for big business and Tory friends.

I ask you to join me in standing up for what we signed up to in Paris and vote for change. The opportunity is here to send a clear message and we must take it.
