Summary
In Table 1 the results from the verification process of the Danish emission inventory data are summarised. The verification process has been tested on 21 Danish key source categories that have been identified from total emitted amounts and trend assessment. For each key source an indicator is chosen that will enable an inter-country comparison of emission density indicators, defined as the emissions/indicator ratio. The indicators are mainly taken from the Norwegian verification report (Holtskog et al., 2000). The verification process is performed for three years, 1990, 1997 and 2003.
Table 1
Summary of verification of Danish Key Source Categories. Verification is based on 1) Agreement between calculated emission density indicator and reported implied emission factor (+ = good agreement, - = poor agreement, no = no reported emission factor), 2) Agreement between calculated emission density indicator and Danish value for CO2 content in fuel (or other relevant factor) (+ = good agreement, - = poor agreement, no = no relevant factor), and 3) Consistency in time, explained decrease or increase (+ = good, - = poor, no = missing data). Comparable countries with respect to calculated emission density indicators are stated for each key source category.

For each key source there are four verification parameters. First, the agreement between the calculated emission density indicator and the reported (if any) implied emission factor. Second, the agreement between the calculated emission density indicator and a theoretical value for the CO2 content in fuel (or other relevant parameter). Third, an evaluation of the time trend of the calculated emission density indicator. And fourth, a comparison of emission density indicators between countries.
It is seen that there is good agreement for verification parameter 1 for the energy key source categories. This is probably due to a good correlation between the reported emission intensity values and the chosen indicators, implying good cause and effect relationship. Furthermore there is good agreement between the emission density indicator and the conversion factors for coal, oil and gas, respectively. There is good consistency in the time trends, and the inter country comparison shows good agreement between <st1:country-region w:st="on">Denmark</st1:country-region> and <st1:country-region w:st="on">Netherlands</st1:country-region> , <st1:country-region w:st="on">Spain</st1:country-region> and <st1:place w:st="on"><st1:country-region w:st="on">UK</st1:country-region></st1:place> .
For the agriculture key source categories there are no reported implied emission factors, which leave out the first verification parameter. For enteric fermentation there is a Danish emission value that is in good agreement with the emission density indicator. For the industry source category cement production there is a factor recommended by the IPCC that is in good agreement with the emission density indicator. There is an explained time trends for all agricultural and industrial key source categories. There are no countries that are consistently comparable.
For the waste key source category, there is poor agreement between the emission density indicator and the implied emission factor, good consistency in time trend (two years), and good comparability with <st1:place w:st="on"><st1:country-region w:st="on">Austria</st1:country-region></st1:place> only.
In conclusion the used verification procedure is appropriate for evaluating data consistency and reliability for some sectors. For the energy sector the procedure has been appropriate. For agriculture the implied emission factors are not reported, which make part of the suggested verification procedure impossible. For all sectors the method gives good possibility for checking consistency in time trends. An important aspect is to identify appropriate indicators, which represent the key source category. Mainly for the energy sector there is cause effect relationship between the emission and the indicator, which gives a good basis for verification. For the other sectors there are more or less appropriate relationships, and similarities in geography, climate, industry structure and level of economic development may be necessary to include in order to obtain comparable emission density indicators. In these cases it is important to note that the verification only considers consistency compared to how and what other countries report. It is not a verification of the scientific value of the inventory data themselves (Holtskog et al., 2000).
