central high scenario, the effects from SOx, NOx, VOCs and PM, even using the<br />

relatively conservative damage costs, are around £3.19 per tonne for incineration<br />

(319 times what is stated in the report) and £0.83 and £0.35 for the two landfill<br />

scenarios.<br />

By way <strong>of</strong> comparison, if the same emissions data is used, but one uses the high end<br />

estimates from the CAFÉ work, the externalities associated with the same pollutants<br />

are in excess <strong>of</strong> £15.00 per tonne for incineration, and around £6.00 per tonne for<br />

landfill with flaring. The differential is particularly great for NOx. In the majority <strong>of</strong><br />

studies reviewed by the main author <strong>of</strong> this study, NOx-related externalities have been<br />

significant contributors to the non-GHG externalities associated with incineration. The<br />

Enviros and EFTEC report effectively reduces their significance by assigning what<br />

appears to be an extremely low unit damage cost for NOx. The incorrect calculation in<br />

the HM Customs & Excise work exacerbates this. 1172<br />

61.3.3 Dijkgraaf & Vollebergh<br />

As part <strong>of</strong> a larger report by the Copenhagen based Environmental Assessment<br />

Institute, Dijkgraaf and Vollebergh ask whether available social cost-benefit<br />

evaluations <strong>of</strong> waste disposal provide support for the strict application <strong>of</strong> the waste<br />

hierarchy. 1173 Of studies reviewed, two found incineration to be preferable to landfill<br />

from a social cost perspective, in support <strong>of</strong> the EU hierarchy. However, three other<br />

studies find that landfilling is the best option.<br />

The report also refers to an earlier study by the same authors. 1174 This detailed the<br />

findings in terms <strong>of</strong> private, environmental and total social costs arising from<br />

landfilling and incineration. This multiplied the net private and environmental costs<br />

per tonne <strong>of</strong> each treatment option in each <strong>of</strong> the EU-15 countries by total municipal<br />

waste arisings for that country. While total environmental costs for landfill are shown<br />

to be higher, the private costs <strong>of</strong> incineration are much more significant, with the<br />

overall result that the social costs <strong>of</strong> incineration are greater than those for landfill.<br />

These results are shown in Table 61-4.<br />

The authors quite rightly add a number <strong>of</strong> qualifications that must be borne in mind<br />

when interpreting these results, notably, the extent to which methane is used as a<br />

source <strong>of</strong> energy generation. This can have a great influence on the relative social<br />

costs <strong>of</strong> landfilling versus incineration. 1175 This is due not only to savings in energy<br />

1172 The Enviros and EFTEC report reviews ten secondary studies which provide valuation data for NOx.<br />

Only one has used a figure for NOx which is lower than the ‘high’ value derived in the context <strong>of</strong> the<br />

Enviros and EFTEC study. That study was carried out in 1995. All the others that were reviewed have<br />

been conducted more recently.<br />
