The industry classification in the tables is the same as the one used in the national accounts. The tables can therefore be compared to other statistics based on the industry classification. Accounts are compiled in form of time series. For example accounts for air emissions are available for each year from 1990 until the last year that is published. Accounts are consistent and fully comparable within these years. On the more aggregated level (NACE 64), the Danish accounts are comparable with accounts of other EU countries compiled according to the Regulation no. 691/2011 on European environmental economic accounts.
Comparability - geographical
Internationally there is a high degree of comparability with other countries, as the Danish Environmental accounts follow the same principles and methods as described in SEEA- framework.
Comparability over time
The environmental accounts for Denmark are based on a number of economic statistics, as well as information on scientific facts. To this must be added a number of assumptions. Since more information from different sources is gradually entered into the environmental accounts, and since the scientific methods used to estimate the physical impact on the environment are constantly improved, the revision policy for the physical part of the environmental accounts deviates from that of the economic part. This means that the information for the physical part of the Environmental Account constantly will be revised, if new sources or new scientific methods lead to a change in the estimations. This also holds for the information from years that are characterized as final. The final economic data and the energy data are only rarely revised (general revisions). In this way data for the environment and resources are revised from time to time. For that reason there can be a difference in the environmental accounts from one publication to the next. Normally, however, full consistency over time will be found within the same publication.

Coherence - cross domain
- Economic data: The industry classification in the tables is the same as the one used in the national accounts. The tables can therefore be compared to other statistics based on the industry classification.
- Data on environment: A number of the environmental data (e.g. total CO2 emissions) that is part of the environmental accounts for Denmark deviates from similar environmental statistics. That is due to different definitions and boundaries.
Coherence - internal
There is a high degree of internal consistency.
