Letter calling on the Energy Secretary to publish a fossil fuel transition roadmap

I have written to the Secretary of State for Energy Security and Net Zero, Miatta Fahnbulleh, to urge her to move swiftly to publish a comprehensive fossil fuel transition roadmap for the UK ahead of COP31 in November.

Dear Secretary of State,

RE: Securing a fossil fuel transition roadmap for the UK

I am writing on behalf of the Green Party of England and Wales to urge your

department to move swiftly to publish a comprehensive fossil fuel transition roadmap

for the UK ahead of COP31 in November.

The impacts of the climate and nature emergency are escalating at a terrifyingly

dangerous rate, as global temperatures continue to climb rapidly. The UK has just been

hit by a summer of extreme heat and wildfires, claiming thousands of lives. Ongoing

gas price volatility continues to drive household energy bills up. And extreme drought

is hammering British agriculture, with consecutive failed harvests costing farmers

nearly £4.8 billion in lost revenue. At the same time, the poorest peoples of the world,

with the least historic responsibility for climate emissions, continue to bear the brunt

of climate breakdown.

As you will be aware, nearly a year ago, at COP30 in Belém, the UK endorsed a fossil

fuels transition roadmap. More recently, at the Santa Marta TAFF conference in April,

the UK reiterated its support for such a roadmap. Since then, France, Germany and the

Netherlands have all published plans.

In this context, it is unacceptable that the government is still yet to publish a

comprehensive domestic roadmap and instead seem to be getting ready to green-light

new oil and gas fields, Jackdaw and Rosebank.

With COP31 fast approaching, it is vital that your department change course and

commit to publishing a roadmap before the start of the summit, including:

• Enforceable target dates for phasing out all fossil fuel extraction, ending new field
  approvals, and winding down unabated fossil generation.
• Managed reduction of North Sea production paired with accelerated electrification
  across UK housing, transport, and heavy industry.
• An end to fossil fuel tax breaks and redirecting capital toward grid infrastructure,
  energy efficiency, and a fully funded Just Transition framework for North Sea
  workers and supply chain communities.The UK cannot claim global leadership at COP31
  while expanding fossil fuels at home.
• Ending all new licenses – including Jackdaw and Rosebank – and publishing a clear
  roadmap will demonstrate that the UK is not merely calling for global transition, but
  actively delivering the domestic plan required to deliver one.

Can your department confirm that such a roadmap will be published before COP31?

And will you meet with me to discuss how we can work together to advance this

strategy?

Yours sincerely,

Carla Denyer MP

Green Party Spokesperson for Energy and Net Zero
