Appendix 8 Full Results of the Benefits Analysis
Results are presented here for the two scenarios, J1 and H1 in that order, with results in all cases incremental to the UKREF scenario for the UK. Results for each scenario are presented in three sets:
Results are expressed as impacts or monetary benefits for one year only (2010). There will be additional benefits before and after 2010 of course, just as there will be additional costs. For chronic effects (on health, forests, etc.) benefits are quantified such that they include benefits in years beyond 2010 arising from emissions abatement in that year compared to UKREF
The sources of the input data were shown in Appendix 6: exposure-response functions and valuation data are given in column 3 of each table. Reference to Appendix 6 is needed to identify the units of the functions given.
The Tables provide the basis for the sensitivity analysis in this report. We start with the effects that can be quantified with the greatest confidence and proceed sequentially through to the most debatable effects. To this is added additional sensitivity analysis, providing high and low estimates for the most significant effects, and for their valuation. This allows the development of ranges down through the Tables for the accumulated high and low totals. These totals are coloured red to the point where benefits outweigh costs, the switching point being coloured green.
Yellow blocks contain data on the physical/biological effect of pollution abatement, and blue blocks the monetised equivalents. Impacts may be separated from their monetised equivalent where the monetisation process is considered to introduce significant uncertainty.
All cost data are given in 1990£ million, for direct comparison with the cost estimates. Unit valuation data given in column 3 of each data are, however, expressed in the original units (1990 euro).
For each type of effect we have sought to calculate upper and lower bounds. These are then fed through to the upper and lower running totals respectively. Final ranges are extremely broad, though we believe still useful (see section 6.9).
