The issue of air quality is under the remit of my colleague, the Minister for the Environment, Community and Local Government who advised that an environmental monitoring programme is undertaken by the Environment Protection Agency, which publishes a comprehensive annual report on air quality. The most recent report "Air Quality in Ireland 2010 — Key Indicators of Ambient Air Quality" was published in September 2011 and will be of interest to the Deputy. I understand that this report provides an overview of ambient air quality trends in Ireland in 2010 based on data from 28 monitoring stations. The Report confirmed that air quality in Ireland is of a high standard and remains the best in Europe.
