A ban on the burning of smoky coal and other prohibited fuels now applies in all smoky coal ban Low Smoke Zones (LSZs), to complement the ban on the marketing, sale and distribution of those fuels in those areas. This means that even "smoky" fuels bought elsewhere cannot now be burned in a Low Smoke Zone.
The smoky coal ban allowed significant falls in respiratory problems and premature deaths from the effects of burning smoky coal in the existing Low Smoke Zones. The original ban in Dublin is cited widely as a successful policy intervention and has become something of an icon of best practice within the international clean air community. Approximately 8,000 premature deaths have been averted in Dublin since the introduction of the smoky coal ban back in 1990.
