Professor Nicola McEwen and Dr Alexandra Remond examine how, in the longer term, Brexit poses significant risks for the climate and energy ambitions of the devolved nations. These include the loss of European Structural and Investment Funds targeted at climate and low carbon energy policies, from which the devolved territories have benefited disproportionately. European Investment Bank loan funding, which has financed high risk renewables projects, especially in Scotland, may also no longer be as accessible, while future access to research and innovation funding remains uncertain. The removal of the EU policy framework, which has incentivised the low carbon ambitions of the devolved nations may also result in lost opportunities.
