The Department of Agriculture, Environment and Rural Affairs (DAERA) has published a synopsis of responses to its consultation on proposals to strengthen Northern Ireland's legal air quality standards for particulate matter, with the aim of protecting public health and delivering cleaner air.

The 12-week consultation on the draft Air Quality (Amendment) Regulations (Northern Ireland) 2026 closed on 31 August 2026 and proposed tighter annual average limits, targets and objectives for PM2.5 and PM10. The measures are intended to support actions in the draft Clean Air Strategy and the draft Climate Action Plan.

Analysis of the submissions shows broad support for the plans, with most respondents agreeing that more stringent particulate matter standards should be introduced. Particulate matter found in fumes and smoke can be harmful to health, irritating the respiratory system and increasing the risk of heart disease and stroke.

Commenting on the consultation responses, Minister Muir said: "Strengthening Northern Ireland's legal air quality standards will bring us in line with tightening air quality standards across the UK and align with more up-to-date international guidance. These measures will help improve air quality, protect public health and create a cleaner, healthier environment for current and future generations.

"I am pleased that recent monitoring indicates these targets are achievable, with most monitoring sites already meeting the proposed limits. The new regulations will also support delivery of the draft Clean Air Strategy, which is currently out for consultation and complement wider environmental and climate action commitments."

Subject to Assembly approval, the Regulations will be introduced later in 2026, establishing updated particulate matter standards that reflect the latest evidence on air quality and associated health impacts.
