Ym mis Rhagfyr 2016, cynhaliodd Pwyllgor y DU ar Newid Hinsawdd (UKCCC), ein Corff Cynghori Annibynnol, gais am dystiolaeth, gan holi barn rhanddeiliaid pa allyriadau y dylid eu cyfrif a’n dull o’u cyfri yng Nghymru.  Hyrwyddodd Llywodraeth Cymru yr alwad hon am dystiolaeth gan gynnal digwyddiad ar y cyd i randdeiliaid gyda’r UKCCC ym mis Ionawr.
In December 2016, the UK Committee on Climate Change (UKCCC), our independent Advisory Body, hosted a call for evidence, seeking stakeholder’s views on what emissions should be counted and the way we count them in Wales. The Welsh Government promoted this call for evidence and hosted a joint stakeholder event with the UKCCC in January.
