This document summarizes the historical background and challenges of regulating solid fuel use in Dublin to improve air quality. It outlines how areas were progressively designated where the marketing, sale, and burning of bituminous coal and other solid fuels with high sulfur content were prohibited starting in 1990. While initial successes were had, public perception of improved air quality did not always match reality. Ongoing challenges include the need to reconsider how areas are designated given population density; addressing the all-island trade of solid fuels; taking a multi-agency regulatory approach; and increasing public information campaigns given growing knowledge of health impacts of air pollution.
