Differences/advantages to air emission inventory; added value
Let me just give you a short description of the differences between Air emission accounts and the Inventories, that are the basis for the international reporting obligations like UNFCCC and UNECE-CLRTAP and the added value that is given from Air emission accounts.

Air Emission Accounts
Territorial principle
Residence principle
Process-based allocation of emissions
Allocation of emissions to economic activities
Breakdown by seven sectors (Energy, industrial processes; solvent and other product use; agriculture; land use, land-use change and forestry; waste; other)
Breakdown by industries (NACE 2-digit level) and households
Functional allocation of transport emissions
Territorial principle: All emissions within a given country are taken into account, irrespective of whether they are emitted by domestic or foreign institutional units.
Residence principle: Only such data is taken into account that can be assigned to domestic institutional units, irrespective of whether they perform their work or services within the national territory.
Process-based allocation of emissions: Emissions are broken down to production and consumption processes, based on SNAP (Standardized Nomenclature for Air Pollutants) or other process-based classifications that are not as detailed as SNAP.
Allocation of emissions to economic activities: This is the next step after the process-based allocation of emissions. It consists of assigning emissions from activities (SNAP processes) to the individual economic sectors and the private households institutional sub-sector.
Breakdown by seven sectors vs. By industries and households (NACE 2-digit level).
With emissions from transports we have to pay attention to teh fact, that in the inventories transport is a special functional sector, whereas within AEA transports-emissions are to be assigned to the individual economic sectors and the private households – subdivided into residents and foreigners.
Allocation of transport emissions to the final producer

Possible uses of Air Emission Accounts = value added!
Analysis of production-related emissions of industries and households (across countries, over time)
Environmental-economic profiles of industries (contribution of a specific industry to total emissions of an economy, e.g. by pollutant or GHG, by fuel etc.)
Measurement of (relative or absolute) decoupling effects and of air emission intensities of industries (latter: emissions per unit output)
Some examples for possible uses…………….
Use for Structural Decomposition Analyses (Analysis of the reasons for changing production-related air emission levels of industries over time)

4. Differences/advantages to air emission inventory; added value
Possible uses of Air Emission Accounts = value added! (cont.)
Calculation of indirect air emissions related to domestic final use by product group (combining Air Emission Accounts and input- output tables to environmentally extended input-output tables allows for the calculation of air emissions arising in domestic production processes and in the rest of the world through imports)
Calculation of indirect air emissions by final use categories (exports, gross fixed capital formation, final consumption)
Indirect emission refer to emissions that occur with imports of products. This is similar to hidden flows within MFA.
Splitting indirect air emissions related to domestic final use by product group into domestic and foreign origin

5. Differences/advantages to air emission inventory; added value
Possible uses of Air Emission Accounts = value added! (cont.)
Analysis of consumption related air emissions over time by using Structural Decomposition Analysis (it enables the analysis of the change of air emissions caused worldwide along the production chain of consumed products)
Analysis of air emission intensities of product groups over time from the consumption perspective (emissions per unit final use of a product group)
