Climate change is a global crisis, but how does it impact Ireland? While Ireland’s temperate climate has historically shielded it from the most extreme effects seen elsewhere, the evidence of change is now clear and growing.
This article outlines key challenges we face with climate change in Ireland and the urgent actions required to address them.

What is Climate Change?
Climate change refers to long-term shifts in the Earth’s climate. The most significant aspect is global warming, the steady rise in the planet’s temperature. Global warming is caused by “the greenhouse effect”. This greenhouse effect occurs when gases, like carbon dioxide (CO₂) and methane (CH₄), trap the Sun’s heat in the Earth’s atmosphere.
The greenhouse effect is natural and necessary for life. Without it, Earth’s average temperature would be -18°C. However, human activities (like burning fossil fuels and cutting down forests) add extra greenhouse gases to Earth’s atmosphere. This results in excess heat being trapped, causing global warming. Global warming leads to climate change, bringing effects like stronger storms, rising sea levels, and changing weather patterns.
Climate Change in Ireland
2025 was Earth’s third hottest year on record, marking an 11-year streak of temperatures above normal, according to Europe’s Copernicus climate monitoring service. At present, climate change in Ireland can be seen in line with global trends:
⚠️ Ireland has warmed by 0.7°C and become 7% wetter when comparing 1961-1990 to 1991-2020.
⚠️ Extreme weather events like storms and flooding are becoming far more frequent. Ireland also had its warmest summer on record despite no official heatwave being declared, as unusually warm nights kept overall temperatures elevated.
⚠️ Around Ireland sea levels have risen by ~2-3 mm per year since the 1990s.
⚠️ Ireland’s climate progress is slowing, not accelerating: the country now ranks 33rd in this year’s Climate Change Performance Index, down four places from the previous year, with the rate of greenhouse gas emissions decline slowing to just 2% compared with 6.8% the year before.
Future Impacts on Ireland
🚩Agriculture: By 2050, temperatures could rise by 1.3–1.6°C, leading to hotter summers and milder winters. Crop yields will suffer due to increasing drought conditions.
🚩Extreme Weather: Winters could become up to 24% wetter. Increased rainfall and storm activity will increase flood risks and property damage.
🚩Coastal Areas: 40% of Ireland’s population lives within 5km of the coast. As a result, roughly 70,000 Irish addresses could be at risk of coastal flooding by 2050.
🚩Health: Heatwaves and poor air quality will become more common, causing more heat-related illnesses and respiratory problems.
🚩 Biodiversity: Native species will be at risk due to temperature and rainfall changes. New invasive species and pests may thrive.
🚩 Water Quality & Supply: Warmer temperatures and heavier rainfall increase the risk of harmful algal blooms in the rivers and lakes that supply Ireland’s drinking water, while more intense storms raise contamination risks for private wells and group water schemes. Regular testing helps households stay ahead of these changing risks.
The Economic Cost of Climate Inaction
The EU Effort Sharing Regulation (ESR) sets binding targets for EU nations to cut emissions. It covers transport, buildings, small industry, waste, and agriculture. Under the ESR, Ireland must reduce emissions by 42% (compared to 2005 levels) by 2030. However, Ireland has the worst per capita emissions gap in the EU – projected to exceed our emissions limits by up to 57%.
Failing to meet targets will be very costly. Countries must buy carbon credits from other EU nations to cover shortfalls. These payments could cost Ireland between €8–26 billion if current trends continue. This financial strain will take funds away from public services and infrastructure.
Ireland’s wider national target, a 51% cut in emissions by 2030 under the Climate Action and Low Carbon Development Act 2021, is also falling short. The latest EPA projections indicate Ireland is, at best, on course for a 23% reduction by 2030, well below the 51% commitment enshrined in climate law. Ireland’s carbon tax, a central tool in the national climate strategy, rose to €71 per tonne of CO₂ in Budget 2026 and is legislated to reach €100 per tonne by 2030, reflecting the rising cost of the transition for households and businesses alike.
Solutions for Climate Change in Ireland
✅ Renewable Energy Expansion
➜ Increase investment in wind and solar power to reduce reliance on fossil fuels.
➜ Upgrade the national power grid to integrate more sustainable energy.
✅ Agricultural Reforms
➜ Promote afforestation (tree planting) to absorb CO₂ and restore biodiversity.
➜ Support farmers in adopting sustainable land use practices that reduce environmental impact.
✅ Sustainable Transport & Infrastructure
➜ Expand and improve public transport networks to reduce car dependency.
➜ Incentivise the use of electric vehicles (EVs) and cycling infrastructure – grants of up to €3,500 plus VRT relief of up to €5,000 are currently available to help offset the upfront cost.
✅ Carbon Sequestration & Land Restoration
➜ Enhance soil management techniques to increase carbon storage.
➜ Expand nature-based solutions, such as wetlands and forest conservation, to act as carbon sinks.
✅ Policy & Public Engagement
➜ Implement stronger climate laws that enforce emissions reductions.
➜ Provide incentives for businesses and individuals to reduce their carbon footprint. Homeowners can currently access SEAI grants of up to €12,500 for heat pumps and up to €1,800 for solar panels.
