Aberpergwm coal mine - why it matters

FoE Cymru & FoE Cardiff are actively campaigning to stop an expansion to the existing Aberpergwm deep coal mine in South Wales to extract a further 42 million tonnes of coal, emitting around 100 million tonnes of CO2 and up to 1.17 million tonnes of methane, until 2039. The licence for the expansion has been issued by the UK Coal Authority, we are now seeking to challenge that decision in court - we are doing so in collaboration with Coal Action Network, Greenpeace local groups, XR Cymru, Wales Green party and Wales Libdem party.

Cardiff FoE supports in organising and participating in protests, as well as in sharing the information and liaising with different local groups whose members might be from South Wales and feel like the issue is close to home.
