Ireland’s latest EPA greenhouse gas emissions update brings a rare piece of climate news with clear momentum: emissions fell for a fourth consecutive year in 2025, even as the economy and population continued to grow. In a statement published on gov.ie, the Department of Climate, Energy and the Environment said the new figures confirm that Ireland has now reached its lowest greenhouse gas output in 36 years.
The provisional inventory, published by the Environmental Protection Agency (EPA), also indicates that Ireland has achieved its first Carbon Budget. That marks an important milestone for national climate policy and adds weight to the government’s case that economic expansion can happen alongside lower emissions.
EPA Greenhouse Gas Emissions Show Four Straight Years of Decline
The 2025 data points to a broad-based reduction across the main sectors of the economy. According to the government, this is the fourth year in a row that emissions have fallen, reinforcing the direction of Ireland’s wider Climate Action agenda.
- Ireland recorded its lowest greenhouse gas emissions level since 1989
- The first Carbon Budget was achieved
- Emissions dropped across all major economic sectors
- Energy industries saw a 7.1% reduction, reaching an all-time low
This matters because the decline happened during a period of major national growth. Over the longer term, Ireland has added roughly 1.5 million people, more than one million homes and over one million vehicles, yet emissions have continued to move downward.
Economic Growth and Lower Emissions Can Coexist
One of the strongest messages from the EPA greenhouse gas emissions report is that economic growth has become increasingly decoupled from emissions. While Ireland’s economy expanded strongly in 2025, greenhouse gas output still fell. For policymakers across Finance, Transport, Housing and Enterprise, Trade and Employment, that is a significant benchmark.
Household emissions also reached record lows in 2025, suggesting that cleaner energy, efficiency gains and changing transport choices are starting to register in daily life.

Renewable Electricity and Transport Help Drive the 2025 Fall
A major share of the progress came from cleaner electricity. The government said emissions from energy industries fell 7.1% in 2025, helped by long-term investment in renewable power. Electricity generation from renewables has increased fivefold since 2005, and for periods in the first half of 2026, almost half of Ireland’s electricity demand was met by renewable sources.
The transport sector also contributed to the downward trend. Higher biofuel use and faster adoption of electric vehicles helped reduce emissions further, an outcome closely linked to policy areas involving the National Transport Authority (NTA) and the Road Safety Authority (RSA).
What Minister O’Brien Said
Minister Darragh O’Brien said the publication of the EPA greenhouse gas emissions inventory was encouraging as Ireland works toward a climate-neutral economy. He described achievement of the first Carbon Budget as a significant national success and said the next update to the Climate Action Plan would focus on high-impact measures that lower emissions while improving quality of life.

Why the 2025 EPA Greenhouse Gas Emissions Report Matters
The latest EPA greenhouse gas emissions figures suggest Ireland is making measurable progress, not just setting targets. With support from government departments including the Department of the Taoiseach, Public Expenditure, Agriculture and Local Government, the next challenge will be maintaining the pace of reductions as demand for energy, housing and transport continues to rise.
For readers tracking climate, economy and public policy through gov.ie, this report offers a clear takeaway: Ireland is cutting emissions while still growing, and that shift is becoming harder to dismiss as a one-off trend.
