Cut Carbon is a major £5m investment in decarbonising transport by the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI). Five Decarbonising Transport Networks have been funded to bring together expertise from across academia and industry to lay the groundwork for the use of low carbon technologies across the road, rail, marine and air networks. Each network has its own specialist focus area ranging from examining commercial flights using electric airplanes, through smart vehicle to grid connectivity challenges to decarbonising freight transport. The Cut Carbon initiative acts as a one stop shop for finding out about events, funding calls and key network deliverables across all of the networks, recognising the need for a whole system approach to rapid decarbonisation. It will share syntheses of the latest understandings of decarbonisation solutions and will help connect industry, government and academia and signpost to the more in-depth studies on-going in each of the networks.
