"Er mai prif nod y cynllun yw lleihau crynodiadau o NO2 &nbsp;o amgylch ffyrdd lle y mae'r lefel yn uwch na'r terfyn cyfreithiol, rydym hefyd yn datblygu gwahanol fesurau eraill er mwyn gwella ansawdd yr aer. Rydym wedi ymrwymo i wella ansawdd yr aer yng Nghymru drwy fesurau cynllunio, seilwaith, rheoleiddio a chyfathrebu o ran iechyd."
“While the focus of this plan is to reduce concentrations of NO2 around roads where exceedances have been identified, we are developing a range of other measures to improve air quality. We are committed to making improvements to air quality in Wales through planning, infrastructure, regulation and health communication measures.”
