Dywed yr CCC fod tystiolaeth newydd yn dangos y gallai mwy o ostyngiadau yn y sector diwydiannol helpu i daro’r nod, gan fod cyfran fawr o allyriadau Cymru’n cael eu cynhyrchu gan nifer fach o lygrwyr mawr, fel gwaith dur Port Talbot.
The new evidence from the CCC says greater reductions within the industrial sector will help achieve this goal, as a large proportion of Welsh emissions come from a small number of big emitters, such as Port Talbot steelworks.
