The 31 local authorities in Ireland took more than 850 prosecutions for breaches of environmental standards in 2018.
That's according to a new report from the Environmental Protection Agency, focusing on councils' environmental enforcement performance in 2018.
It says councils increased their enforcement activities over the course of the year.
There were 168,000 inspections, along with 20,000 enforcement actions and more than 850 prosecutions.
Many of these prosecutions were taken because people didn't pay litter or waste fines.
Local authorities received 78,000 environment complaints - 90 per cent of which related to litter or waste.
The EPA says councils are performing well, but says more focus is needed to ensure people segregate their waste, to support better recycling.
