Ar 29 Tachwedd 2011 cyhoeddais fy mhenderfyniad polisi i fynd ati i sefydlu un corff amgylcheddol i Gymru. Gwnes fy mhenderfyniad ar ôl ystyried yn ofalus yr achos busnes manwl a ddatblygwyd dros y naw mis blaenorol.
On 29 November 2011 I announced my policy decision that I was minded to proceed with establishing a single environment body for Wales.  This was taken following careful consideration of the detailed business case which had been developed over the previous nine months.
