Air Pollution Act, 1987 (Sulphur Content of Heavy Fuel Oil and Gas Oil) Regulations, 2001 (S.I. No. 13 of 2001).

The Regulations prohibit the use in the State of heavy fuel oils with a sulphur content exceeding 1 percent by mass from 1 January 2003. The Regulations replace the ban on the marketing of gas oils with a sulphur content exceeding 0.2 percent by mass (in operation since 1 October, 1994) with a ban on the use of these oils. The Regulations also provide for further sulphur reduction to a content not exceeding 0.1 percent by mass from 1 January 2008. The Directive widens the definition of "gas oil" so that the Regulations now encompass both aviation kerosene and marine gas oils.
