Mae'r Ddeddf newydd yn parhau gyda'r gofyniad bod rhaid defnyddio'r cyllid at ddibenion amgylcheddol neu gymdeithasol. Hyd yma, mae £37.7miliwn wedi ei ddyrannu i Gymru trwy'r cynllun Cyfrifon Segur presennol ac wedi ei ddefnyddio i ariannu prosiectau ar weithredu ar newid hinsawdd, i hyffordd pobl ifanc, ac addysg a chyflogaeth. Fe'i dosberthir hefyd yn unol â'r egwyddor ychwanegol: ni ellir defnyddio'r arian yn lle gwariant y llywodraeth.
The new Act continues with the requirement that the funding must be used for environmental or social purposes. To date, £37.7m has been allocated to Wales through the existing dormant accounts scheme and has been used to fund projects on climate change action, to train young people, education and employment projects. It is also distributed in line with the principle of additionality – the money cannot be used as a substitute for government spending.
