Air Quality in Ireland 2025
Year: 2026
Air quality in Ireland is generally good, meeting air quality limits for 2025 and with pollutants decreasing over the last 20 years. When air pollution occurs, it causes significant health impacts. Despite meeting EU air quality limits, there are around 1,500 premature deaths a year linked to air pollution. Local authorities play a vital role in improving air quality through the enforcement of solid fuel regulations, promoting home retrofitting, promotion of active travel, and public awareness initiatives.

Ireland's Third National Implementation Plan for Persistent Organic Pollutants
Year: 2026
Persistent Organic Pollutants (POPs) are a group of hazardous chemicals that persist in the environment, can bioaccumulate in the food chain, and can be toxic to human health and the environment. Examples of POPs include some older pesticides such as DDT, flame retardants found in older furniture, specific types of industrial chemicals, some of which were used in firefighting foam, and pollutants released from illegal burning of waste. The UN Stockholm Convention on POPs is a global treaty which aims to protect human health and the environment from POPs. Ireland became a Party to this Convention in 2010 and is required to develop a National Implementation Plan (NIP) on POPs and update it as necessary. New POPs have been identified globally in the past few years. In 2026 the EPA updated Ireland’s National Implementation Plan for Persistent Organic Pollutants to include these new chemicals.

Quarterly Greenhouse Gas Emissions Indicator Report 2026 Quarter 1
Year: 2026
This is the latest EPA report on quarterly greenhouse gas emissions for Ireland, supporting more frequent monitoring of national and sectoral progress on climate action. This series complements the national greenhouse gas inventory and projections prepared annually by the EPA. Emissions in Quarter 1 2026 were down by 0.8% compared with the same quarter last year. This was mainly driven by decreases in the Transport sector (-72.1 kt CO₂ eq), reflecting lower road transport emissions, and the Electricity sector (-33.3 kt CO₂ eq), reflecting increased renewable generation and electricity imports alongside reduced non-renewable generation. These decreases were partially offset by increases in the Agriculture sector (+25.6 kt CO₂ eq) and the Industry sector (+8.1 kt CO₂ eq).
