Diben y gynhadledd ar 9 Gorffennaf 2015 oedd trafod ac ystyried â’r holl randdeiliaid sut i drechu’r heriau sy’n gysylltiedig â llwyr-adfer safleoedd mewn ffordd gynaliadwy pan ddaw oes safle glo brig i ben.  Addewais y byddwn yn ystyried y cyfraniadau ac yn nodi fy mwriadau ar gyfer y dyfodol mewn datganiad ysgrifenedig.
The focus of the summit on 9 July 2015 was to discuss and consider with all stakeholders, actions to overcome the challenges of ensuring full and sustainable restoration of sites when opencast coal operations come to an end.  I promised to reflect on the contributions made and set out my intentions for moving forward in a written statement.
