O ran Cam 3, erbyn mis Rhagfyr 2015, mae angen i ni greu rhaglen o fesurau i ennill Statws Amgylcheddol Da erbyn 2020 (a ddylai fod yn weithredol erbyn 2016) a rhaglen o fesurau i'w chyflwyno i'r Comisiwn erbyn mis Mawrth 2016. Mae'r cynigion hyn yn amodol ar ymgynghoriad cyhoeddus ledled y DU gyfan a fydd ar agor tan 27 Ebrill 2015. Fel rhan o'r broses ymgynghori, cynhaliodd Llywodraeth Cymru ddigwyddiad i randdeiliaid ar 6 Mawrth.  Roedd yn bleser gan Lywodraeth Cymru groesawu dros 40 o randdeiliaid amrywiol, yn cynrychioli amrywiaeth o sectorau.
For Stage 3, by December 2015 we need to establish a programme of measures to achieve GES by 2020 (which must be operational by 2016) and programme of measures reported to the Commission by March 2016. These proposals are subject to a UK wide public consultation open until 27 April 2015. As part of the consultation process the Welsh Government held a stakeholder event on 6 March.The Welsh Government was pleased to welcome over 40 stakeholders from a wide cross section, with a range of sectors being represented.
