Ym mis Tachwedd 2011, cyhoeddais fy mwriad i sefydlu Un Corff Amgylcheddol newydd i Gymru a fyddai’n cyfuno swyddogaethau Cyngor Cefn Gwlad Cymru, Asiantaeth yr Amgylchedd Cymru a  Chomisiwn Coedwigaeth Cymru.
In November 2011, I announced that I was minded to proceed with creating a new Single Body for Wales by bringing together the functions of the Countryside Council for Wales (CCW), the Environment Agency Wales (EAW) and Forestry Commission Wales (FCW).
