Yn ogystal â thynnu sylw at effaith gyfunol y Llywodraethau Taleithiol a Rhanbarthol, cefais siarad am y gwaith sy'n cael ei wneud yma yng Nghymru. Yn ogystal â disgrifio llwyddiannau Cymru mewn meysydd megis gwastraff ac arbed ynni, tynnais sylw hefyd at ein deddfwriaeth arloesol, fel Deddf Llesiant  Cenedlaethau'r Dyfodol, y Ddeddf Cynllunio a  Bil yr Amgylchedd. Gyda chymaint o wladwriaethau, rhanbarthau a busnesau’n bresennol, roeddwn hefyd yn awyddus i ddysgu o brofiadau pobl eraill ac felly trefnais gyfres o gyfarfodydd gyda Llywodraethau Taleithiol a Rhanbarthol allweddol eraill fel De Awstralia, Quebec a California. Hefyd, fodd bynnag, o ystyried y rôl bwysig a chwaraewyd gan y sector preifat yn COP21 a'r alwad gan fusnes am gytundeb uchelgeisiol, cynhaliais gyfarfodydd dwyochrog hefyd gyda Banc Buddsoddi Ewrop a Chyngor Busnes y Byd ar Ddatblygu Cynaliadwy.
In addition to highlighting the collective impact of State and Regional Governments, I also discussed the work being delivered here in Wales. I not only showcased Wales’ achievements in areas such as waste and energy efficiency, but also highlighted the pioneering legislation we have brought forward through the Well-being of Future Generations Act, the Planning Act and the Environment Bill. With the attendance of so many states and regional governments and business I was also keen to learn from the experiences of others and I therefore held a series of bilateral meetings with other key partner State and Regional Governments such as South Australia, Quebec and California. In addition, however, given the significant role played by the private sector at this COP and the call from business for an ambitious agreement I also held bilaterals with the European Investment Bank and the World Business Council for Sustainable Development.
