Killarney has maintained its position in the top ten of the latest Irish Business Against Litter (IBAL) survey, securing 9th place out of 40 towns and cities surveyed nationwide. The town was officially deemed to be 'Cleaner than European Norms'.

The accompanying report by An Taisce praised Killarney for delivering a solid performance, noting that there were no heavily littered sites found within the town boundaries.
Several local areas received top marks for maintenance and presentation. Main Street was highlighted as exceptionally well-presented, while Park Road, Muckross Road, and the Knockreer Playground and environs were also singled out for praise. The report noted that the playground area was in very good order across all elements.
However, the inspectors did highlight some areas for improvement. The JYSK site showed slight progress compared to the previous survey but remained classified as moderately littered. The report warned that care must be taken to prevent the location from deteriorating further.
On a national level, IBAL representative Conor Horgan noted that entering the peak tourist season, the country has fewer littered areas than at any time in the past 25 years.
Despite the introduction of the Deposit Return Scheme (DRS), the survey highlighted a national rise in specific waste items. Plastic bottles were found in 19% of all surveyed sites across the country, and drinks cans were present in 22%. The prevalence of coffee cups also reached its highest level since 2023, alongside an increase in cigarette butt litter.
