Over €900,000 was spent cleaning up illegal dumping in Dublin city last year.
That's down around €80,000 on 2020 and has fallen from €1.1 million in 2019.
The council collected 3,200 tonnes of waste last year, falling by 26 per cent over two years.
While the number of complaints about illegal dumping dropped by 9 per cent in 2021, to 12,096 reports.
When a report of dumping is made to the council the rubbish is examined to see if the person responsible can be identified.
But Eithne Gibbons, Head of Waste Management Services, says this is becoming harder to do;
"Unfortunately, due to increased public awareness, GDPR legislation and a general reluctance on the part of private households to
dispose of personal information because of issues such as identity theft this is an increasingly fruitless exercise."
Fianna Fail spokesperson on Local government Paul McAuliffe has welcomed the drop in waste being found but says more needs to be done;
"We need to see new laws brought forward by Fianna Fáil senators adopted by Government to allow better use of CCTV, number plate recognition and drone technology."
