Ymrwymodd Cytundeb Cydweithredu Llywodraeth Cymru Plaid Cymru i "gomisiynu cyngor annibynnol i archwilio llwybrau posibl i sero-net erbyn 2035 – y dyddiad targed cyfredol yw 2050. Bydd hyn yn edrych ar yr effaith ar gymdeithas a sectorau o'n heconomi a sut y gellir lliniaru unrhyw effeithiau andwyol, gan gynnwys sut y caiff y costau a'r manteision eu rhannu'n deg".
The Welsh Government and Plaid Cymru Cooperation Agreement committed to “commission independent advice to examine potential pathways to net zero by 2035 – the current target date is 2050. This will look at the impact on society and sectors of our economy and how any adverse effects may be mitigated, including how the costs and benefits are shared fairly”.
