Un o’r ffyrdd y mae GIG Cymru yn mynd ati i leihau allyriadau carbon yw drwy leihau’r defnydd o anadlyddion sydd â photensial cynhesu byd-eang (GWP) uchel, o dros 70 y cant i lai nag 20 y cant erbyn 2025.
One of the ways NHS Wales is working to reduce carbon emissions is by reducing the use of high global warming potential (GWP) inhalers from more than 70 per cent to less than 20 per cent by 2025.
