This is based on £350m of UK Government enhancement investment (including part of CVL & Cardiff Central) compared with at least £50bn across the UK in total.
Mae hyn yn seiliedig ar fuddsoddiad o £350miliwn gan Lywodraeth y DU ar gyfer gwelliannau (gan gynnwys rhan o CVL a Chaerdydd Canolog) o gymharu ag o leiaf £50 biliwn ar draws y DU i gyd.
