Fel y mae Aelodau’n sylweddoli eisoes, cafodd ymrwymiad ei wneud yn rhaglen Cymru’n Un i sefydlu menter i gefnogi awdurdodau lleol, ac annog gweithredu gwirfoddol, i wella ansawdd yr amgylchedd lleol. Ym mis Ebrill 2008, yn sgil yr ymrwymiad hwnnw, lansiwyd y fenter Trefi Taclus. Nod Trefi Taclus yw galluogi pobl Cymru i gymryd cyfrifoldeb am ansawdd eu hamgylchedd lleol eu hunain, er mwyn iddynt allu chwarae eu rhan i greu Cymru lân, ddiogel a thaclus.
As Members are aware, a commitment was made in One Wales to establish an initiative to support local authorities and voluntary action to improve the quality of their local environment. Tidy Towns was launched in April 2008 as a direct result of that commitment. The aim of Tidy Towns is to empower the people of Wales to take responsibility for the quality of their own local environment so they can contribute towards a clean, safe and tidy Wales.
