bod dwy ran o dair (66%) o’r rhai a arolygwyd yn cytunuo â’r datganiad “mae’r tâl wedi helpu i leihau sbwriel yn ardal fy awdurdod lleol”.oherwydd y gostyngiad sylweddol yn y galw am fagiau siopa untro, a’r cynnydd yn y galw am y mathau o fagiau y gellir eu defnyddio eto (plastig neu ddefnydd), amcangyfrifir bod rhwng £0.9 miliwn a £1.3 miliwn wedi ei godi ar gyfer y cyfnod Hydref 2011– Ionawr 2015.
Two-thirds (66%) of those surveyed agreed with the statement ‘The charge has helped to reduce littering in my local authority area’.Due to the significant shift in demand away from single use bag varieties to re- usable bag types (plastic or fabric), it is estimated that benefits of between £0.9 million and £1.3 million have been achieved for the period October 2011– January 2015.
