Er mwyn mynd i’r afael â’r argyfwng hinsawdd, mae angen creu llawer mwy o goetir yng Nghymru.  Mae angen i ni blannu 43,000 hectar o goetir newydd erbyn 2030, a 180,000 hectar erbyn 2050 i gadw at y ‘llwybr cytbwys’ a ddisgrifir gan Gomisiwn Newid Hinsawdd y DU. Mae hynny’n cyfateb i blannu o leiaf 5,000 o hectarau’r flwyddyn.  Llynedd, dim ond 290 o hectarau gafodd eu plannu yng Nghymru ac nid oes mwy na 2,000 o hectarau wedi’u plannu mewn unrhyw flwyddyn ers 1975.
Wales needs a step change increase in woodland creation to tackle the climate emergency. We need to plant 43,000 hectares of new woodland by 2030, and 180,000 hectares by 2050 to meet the ‘balanced pathway’ set out of the UK Climate Change Commission. That is equivalent to planting at least 5,000 hectares per year. Last year, just 290 hectares of woodland was planted in Wales and annual woodland creation has not exceeded 2,000 hectares since 1975.
