Mae'r Bil, a gyflwynwyd i'r Senedd ym mis Mawrth 2023, yn rhoi mesurau ar waith sy'n cyfrannu at welliannau o ran ansawdd yr amgylchedd aer yng Nghymru ac yn lleihau effeithiau llygredd aer ar iechyd pobl, bioamrywiaeth, yr amgylchedd naturiol a'n heconomi.
The Bill, which was introduced to the Senedd in March 2023, implements measures that contribute to improvements in the quality of the air environment in Wales and reduces the impacts of air pollution on human health, biodiversity, the natural environment and our economy.
