Litter from the air data
We collect data through robust litter surveys using GLÂN (Geospatial Litter Analysis) – our world‑leading methodology for monitoring and analysing litter trends.
These figures show the extent of balloon and firework litter across Wales last year in publicly accessible areas including streets, car parks, parks and green spaces, and designated bathing water beaches.
For all the latest litter survey results, visit our litter data page.
