Nid oes gan brifysgolion a busnesau yng Nghymru fynediad i gynlluniau eraill a ariennir gan yr UE ychwaith, megis rhaglen Horizon a Rhaglenni Cydweithredu Tiriogaethol Ewropeaidd, sy’n golygu bod llai o gyllid o lawer ar gael ar gyfer prosiectau arloesi. Yn ystod rownd olaf cyllid yr UE (2014–20), cafodd mwy na £500 miliwn ei fuddsoddi ym maes ymchwil ac arloesi, gan gynnwys £69 miliwn ar gyfer y rhaglen SMART.
Welsh universities and businesses are also being denied access to other EU funding programmes like Horizon and European Territorial Co-operation programmes, which means significantly less funding for innovation projects. During the last round of EU funding (2014 to 2020), over £500 million was invested in Research and Innovation, including £68 million for the SMART programme.
