A 1990–1991 survey of peat extraction in Northern Ireland for use as fuel and in horticulture was followed by an estimate of carbon loss resulting from this extraction. This estimate formed part of UK annual estimates of carbon emissions and removals due to land use, land-use change and forestry. Subsequently, extraction of peat for fuel appeared to decline so a resurvey of its extent was required. Peat extraction for horticulture continued after 1991, but data comparable with that for 1990–1991 became unavailable. It was necessary to recalculate the amount of extraction for horticulture, and consequent carbon loss, for 1991 using a method that could be applied in a 2007–2008 resurvey. Methodology for the 2007–2008 resurvey of peat extraction for fuel, for the revision of the amount of peat extracted for horticulture in 1990–1991 and in 2007–2008, and for estimation of carbon losses due to peat extraction is described. Between 1990–1991 and 2007–2008 there was an overall decline in carbon loss due to peat extraction to 30–40% of the 1990–1991 estimates, caused mainly by a marked fall in extraction for fuel.
