Ireland’s brand is emerald, and it ranks among the highest in Europe for freshwater available per person. Yet more than half of Ireland’s rivers and lakes are in poor or moderate ecological health. And while Ireland’s air quality is better than in many EU countries, fine particulate levels still breach World Health Organisation (WHO) guidelines.
Ireland’s image as a place of clean air, clear waters, and endless grasslands shapes its tourism campaigns and agricultural exports. But the reality is slightly more complex. It often struggles to balance its agricultural economy with climate science demands and EU directives.
Let’s explore Ireland’s environment in detail and look at some key statistics, including air, water, and soil quality. We’ll also discuss agriculture, biodiversity, and energy use in Ireland.

What Does the EPA’s State of the Environment Report Say?
The EPA’s 2024 State of the Environment report shows both progress and persistent problems. While Ireland continues to meet EU standards for air and drinking water, many rivers, lakes, and estuaries are in poor ecological health. Greenhouse gas emissions have barely fallen since 1990, and remain almost twice the EU average per person. Biodiversity continues to decline, and soil nutrient imbalances increase the risk of pollution.
EPA Director General Laura Burke warned that Ireland needs a “fundamental shift” in how it uses energy, manages land, and protects nature.
How Clean Is the Air in Ireland?
Key stats
- Projected 2030 compliance: 93% for PM2.5, 78% for NO2.
- Ireland’s air monitoring network expanded from 29 stations in 2017 to 115 in 2023.
- About 1,700 premature deaths in the Republic and 900 in Northern Ireland are linked to PM2.5 each year (European Environment Agency).
By European standards, Ireland’s air looks good. In 2023, the country met all legal limits for pollutants, including PM₂, NO₂, SO₂, and ozone. But the WHO sets tougher thresholds, and many monitoring stations here still record particulate and nitrogen dioxide levels above those guidelines. What passes as legal isn’t always safe.
According to the EPA, the EU’s Zero Pollution Action Plan will bring in stricter air quality standards by 2030. Projections show Ireland will only reach about 93% compliance for fine particles (PM₂.₅) and about 78% for nitrogen dioxide (NO₂). Hitting the World Health Organization’s tougher health-based guidelines will be even harder.
The good news is that the monitoring network has expanded rapidly, from just 29 stations in 2017 to 115 in 2023, giving the public far better access to real-time data. Yet the health impacts remain serious. The Irish Heart Foundation, using EEA methods, estimates 1,700 premature deaths annually in the Republic and 900 in Northern Ireland from PM2.5 exposure.
What’s Being Done to Improve Irish Air?
Ireland’s Clean Air Strategy aims to reach WHO guideline levels by 2040, with interim targets in 2026 and 2030. The plan focuses on phasing out solid fuels, electrifying transport, improving building efficiency, and stricter enforcement by local councils. But many rural households still depend on turf and coal, while urban traffic remains a stubborn source of pollution.
Are Ireland’s Rivers, Lakes, and Taps as Clean as They Should Be?
Is Our Drinking Water Safe?
For most people, yes. In 2024, more than 99% of tests on public drinking water supplies met EU standards. But weaknesses remain. The EPA’s Remedial Action List highlights supplies vulnerable to lead pipes, weak treatment, or recurring contamination.
About 45 of these served nearly half a million people in Ireland in 2024. Most still passed testing, but fragile infrastructure leaves them prone to failure. Long boil water notices by Uisce Éireann are a reality in some communities, while private wells depend entirely on local upkeep.
What’s happening to our rivers and lakes?
This is where the cracks begin to show in Ireland’s pristine international image. Only half of rivers and fewer than seven in ten lakes meet “Good” status. This is far below EU Water Framework Directive targets. Fertiliser runoff, wastewater plants, and urban pollution are the main culprits. In County Laois, almost half of the monitored river stretches failed to reach a “Good” status.
How Healthy are Ireland’s Beaches and Coastal Waters?
Beaches are one of Ireland’s most-loved assets, and the standard tends toward excellence year after year. But not all. In 2025, two popular spots, Sandymount Strand in Dublin and Lady’s Bay in Buncrana, were downgraded to “Poor” quality. This was blamed on sewage spills and dog fouling. Overall, bathing water quality in Ireland remains very high by EU standards.
Soil and Land: What’s Happening Beneath the Fields?
The state of Ireland’s agricultural soil
Ireland’s soils are generally fertile, supported by a mild climate and grass-based farming. But only 18% are in the optimal range for pH, phosphorus, and potassium. Poor nutrient balance limits productivity and increases the risk of runoff that harms rivers and lakes. Soil compaction, often caused by heavy machinery on wet fields, reduces porosity by more than 10% and can cut yields by 20%.
Peatlands: tradition meets climate pressure
Peat soils cover around 21% of Ireland’s land—more than almost anywhere else in Europe—and store vast amounts of carbon. But studies show that about 85% of these peatlands are degraded, mainly through drainage, turf cutting, farming, and forestry. When drained, peatlands switch from carbon sinks to carbon sources, releasing greenhouse gases instead of storing them. The EPA highlights this as a major challenge for Ireland’s climate goals.
Biodiversity in Ireland
Key stats
- One in five species in Ireland is at risk of extinction.
- One in three bee species faces extinction.
- Curlew numbers have fallen by more than 90% since the 1970s, while the corncrake is now critically endangered.
Biodiversity loss is one of Ireland’s most urgent environmental challenges. Monitoring shows severe declines in farmland birds such as the curlew and corncrake, while pollinators like bees and butterflies are also under intense pressure. About one in three wild bee species is now threatened, a direct risk to farming and ecosystems that rely on them.
The causes are clear: intensive agriculture, habitat loss, pollution, and climate change. Wetlands have been drained, hedgerows removed, and peatlands degraded, leaving fewer safe havens for wildlife. Nutrient pollution continues to disrupt rivers and estuaries, while coastal development chips away at habitats for waders and seabirds.
There are signs of progress. The All-Ireland Pollinator Plan has rallied farmers, schools, and local communities to restore habitats for bees and butterflies. BirdWatch Ireland and other groups run rewilding projects in bogs and wetlands. This shows recovery is possible when land is managed differently. Still, the EPA warns that without stronger policy and sustained funding, biodiversity decline could become one of Ireland’s most lasting environmental crises.
Energy Consumption and the Climate Action Plan
Ireland’s Climate Action Plan is the national roadmap for cutting emissions and shifting to a more sustainable future. It commits to halving greenhouse gas emissions by 2030 and achieving net zero by 2050. That means big changes in how the country consumes energy.
The Action Plan aims to cut emissions in half by 2030 and reach net zero by 2050. But fossil fuels still supply more than 80% of the country’s energy. Electricity is the bright spot, with renewables (mostly wind) now covering over 40% of demand, ahead of the EU average. Transport and heating remain the hardest problems. Transport uses about 35% of all energy, almost entirely petrol and diesel, while many homes still rely on oil, gas, or peat.
The plan calls for offshore wind, solar, more electric vehicles, and retrofitted homes. Hitting these targets will take strong action from the government, councils, industry, and communities. Without faster change, Ireland could fall short of EU climate goals.
Solutions & Future Pathways for Ireland’s Environment
Ireland is emerald, but it faces real environmental challenges: polluted rivers, biodiversity loss, heavy reliance on fossil fuels, and emissions nearly twice the EU average. These problems are serious, but not beyond repair. Farmers, communities, and local authorities are already driving change through better soil management, circular economy projects, renewable energy, and habitat restoration.
The challenge now is speed and scale. Incremental steps won’t be enough — Ireland needs a fundamental shift to balance growth with environmental protection.

FAQ
What is the biggest environmental issue in Ireland?
The biggest environmental issue in Ireland is the decline in water quality and biodiversity. More than half of rivers and lakes are in poor or moderate health, mainly because of fertiliser runoff, wastewater discharges, and urban pollution. At the same time, one in five species is at risk of extinction, with farmland birds like the curlew and pollinators such as bees under severe pressure. These challenges are closely linked to intensive farming and land use.
Does Ireland have a pollution problem?
Yes, but it’s complicated. By EU standards, Ireland’s air and drinking water are generally safe. In 2023, the country met all legal EU air quality limits, and over 99% of public water supplies passed safety tests. However, many rivers, lakes, and coastal waters still suffer from pollution caused by agriculture and wastewater. Ireland’s air also regularly breaches tougher World Health Organization guidelines for particulate matter and nitrogen dioxide, which are linked to health problems like heart and lung disease.
