Wales and the South West

Together with some of the region's top industry, energy and academic organisations, we are leading the drive towards industrial decarbonisation targets.

From engineering decarbonisation solutions in the South Wales Industrial Cluster to working with water companies to produce hydrogen from sewage waste, we are helping meet net zero carbon goals while securing the future of heavy industry in the region.
