Today, 6th February 2024, Coal Action Network was back in court, this time appealing last year’s decision by the court that the Welsh Government couldn’t prevent an extension at Aberpergwm coal mine. Our legal team believes the Welsh Government can, and we believe it should, stop the Aberpergwm extension—keeping 42 million tonnes of coal underground. At stake in this case is an additional 1.17 million tonnes of methane and up to 120 million tonnes of CO2 would be released.
Barristers Estelle Dehon KC and Asitha Ranatunga (Cornerstone Barristers), supported by Matthew McFeeley (Richard Buxton Solicitors), argued that there is a difference between the authorisation for a coal mine and the licensing for one, particularly in the conditional form.
While the specific legal argument is complicated, the case is really a question of whether the Wales Act (2017) means the Welsh Government, rather than the UK Government’s Coal Authority, gets the final say on whether the Aberpergwm coal mine extension can go ahead.

Aberpergwm deep coal mine supplies 70% of its coal to Port Talbot steelworks, which is expected to significantly reduce its coal demand as it decarbonises.
Welsh Government policy, while not without loopholes, does make a stand against the extraction of coal. Should the 3 appeal judges decide that Coal Action Network’s legal team is correct, the Welsh Government will need to decide whether to allow the extension to happen. A ruling is expected in the next 6—12 weeks.
The UK steel and cement sectors (and to a lesser extent, bricks) are the largest users of coal following the closing down of the UK’s last coal-fired power station in September 2024.

The steel industry produces 9-11% of the annual CO2 emitted globally, contributing significantly to climate change. In 2024, on average, every tonne of steel produced led to the emission of 2.2 tonnes of CO2e (scope 1, 2, and 3). Globally in 2024, 1,886 million tonnes (Mt) of steel were produced, emitting…
Last month we worked with Members of Parliament from various parties on a Westminster Hall debate about coal tip safety and the prohibition of new coal extraction licences. The debate happened 59 years and one day after the Aberfan tragedy which killed 116 children and 28 adults…
Successful, at-scale, examples already exist of cement works burning 100% fuel alternatives to traditional fossil fuels, including pilot projects using combinations of hydrogen and biomass (UK) and hydrogen and electricity (Sweden). Yet, innovations such as use of hydrogen and kiln electrification are…
Within the borders of the Senedd Caerphilly constituency is the proposed Bedwas coal tips re-mining project. In the lead up to the Senedd by-election, Coal Action Network has carried out a survey of the by-election candidates asking for their views about the re-mining of the Bedwas and other…
In 2019, Bryn Bach Coal Ltd applied to expand its Glan Lash opencast coal mine and extend the amount of time it would continue mining coal for. The proposal would see the coal mine swallowing a nearby ancient woodland, hedgerows, and grassland. The proposal was rejected by Carmarthenshire County Council in 2023…
In November 2024, the UK Government announced its commitment to legislating a ban of new coal mining licences. This was a commitment that Coal Action Network had secured a manifesto commitment from the Government for, along with four other major parties…

On July 1st, 2025, CAN organised drop-in session at the Senedd, spotlighting the urgent need for action on Wales’ coal legacy issues. The event saw strong cross-party engagement, with Members of the Senedd (MSs)…
Good on you for fighting this. Although I only have your account of the legal arguments to go on, they look convincing to me. Fingers crossed for a positive outcome!
