Four such submissions have been received in electronic form. In accordance with the procedure for miscellaneous documents, these submissions are reproduced as received and without formal editing. The following examples have been experienced by some Member States and the European Commission. Possible solutions to problems are also discussed. Data collection systems Problems with data collection have been the main reason for difficulties faced by some Member States in submitting emission inventory data on time.
Data collection requires time and personnel resources.
Data on emissions from energy production and the use of energy for annual energy statistics are often collected from various sources. In some Member States new routines for the collection of activity data will improve the accuracy of future inventories. However, discontinuity and irregularities in time series on activity data can cause delay and require more work than originally expected. The EU has identified some elements which need further clarification regarding the presentation of summary information on GHGs, detailed worksheets for fuel combustion, land-use change and the forestry sector, agriculture, and the submission of national inventories on these to the secretariat on an annual basis. These have been the cause of delays in some cases.
