3a.Linking energy flow accounts, energy balances and energy statistics
Energy statistics uses concepts and terminology which are often different from those used in economic statistics. There is a need to identify conceptual and terminological differences and ensure that a bridge between the two approaches is developed. The main differences to be addressed consist of the following:
- Use of the territory principles in energy statistics and the residence principle in energy accounts
- Definitions of transactions (e.g. supply, imports and exports are defined differently)
- Energy accounts present information by economic activity, energy balances by technology. As a result the energy and transformation sectors are not defined in terms of ISIC divisions but in terms of technology used
- There exist various definitions and classifications of energy products. At the highest level, it would be useful to have an agreement on the definitions and classifications of energy products as well as their correspondence with CPC and HS. The classification of energy products should also include renewable energy and be disaggregated by purpose (for energy purposes or other purposes).
3b. Linking emission inventories to emission accounts
Emission inventories follow the methodology developed by UNFCCC and they differ from the emission accounts in several ways including the following:
- Use of the territory principle in the emission inventories and the residence principle in the emission accounts
- Use of sectors based on technology in emission inventories and use of economic activities in the emission accounts
- Treatment of short lived biomass, carbon sinks and land (produced and non-produced).
This would require a close analysis of the differences in the approaches and classifications. The question is how bridge tables linking emission inventories and emission accounts can be developed. Can a correspondence between the IPCC source classification and ISIC be developed?
