1990 is the base year for carbon accounting under the Kyoto Protocol. Carbon emissions for peat and mineral soils are averaged on the basis that peat and minerals soils have comprised 30% and 70%, respectively, of the area afforested since 1990. Using this methodology and taking into account relevant scientific data, average soil emissions are set at 0.5 tonnes of carbon per hectare per year. With regard to sequestration, average rates are derived from area weighted average growth rates of tree species, taken from Irish forest inventory data. The inventory data cover all forests planted on both peat and mineral soil.
My Department, through the National Council for Forest Research and Development, is funding research on many aspects of carbon emission and sequestration in Irish forests. As new data becomes available from the research, emission and sequestration figures will be updated as necessary.
