The differences between these two reports give an interesting insight into the way<br />

that assumptions affect the end result <strong>of</strong> such studies.<br />

In the first report, the authors applied external cost estimates to emissions data from<br />

another study carried out in the UK. This was used because it was being widely<br />

quoted in Ireland (and the UK) as evidence <strong>of</strong> an absence <strong>of</strong> health effects from<br />

incineration. Where landfill is concerned, the figures for emissions are low, partly<br />

because gas capture rates from the landfill are assumed to be high in the study.<br />

For the second report, the authors used their own modelling, developed over a<br />

number <strong>of</strong> years. This incorporates LCA and CBA information, and permits the<br />

modelling <strong>of</strong> the impacts <strong>of</strong> time upon those emissions which do occur over an<br />

extended period <strong>of</strong> time. Typical LCA studies, as previously mentioned, do not permit<br />

this. A lower gas capture rate was also assumed for methane at the landfill.<br />

For incineration, the emissions were modelled ‘back’ to the input waste composition.<br />

Emissions are therefore based upon a full engineering assessment <strong>of</strong> the<br />
