Date released: October 21, 2024

The EPA’s Urban Wastewater Treatment in 2023 report, released today, highlights progress in wastewater treatment, including a 45 per cent reduction in the number of towns and villages discharging raw sewage, since the start of 2023.

Progress, economic prosperity, and health all threatened unless Ireland increases the scale, pace, and ambition of environmental action

Date released: October 02, 2024

Today the EPA published its flagship 2024 State of the Environment Report. The report illustrates that Ireland continues to play catch-up. Our reliance on landfills has reduced dramatically, but we are generating and exporting too much waste. We have made progress in improving air quality in our cities, but we have increasing evidence that even low levels of air pollution impacts our health. While we have addressed serious pollution in many rivers and lakes, we are not making progress on the more widespread water pollution from too much nutrient.
