London Group Meeting – New York, 19-21 June 2006

1. London Group Meeting – New York, 19-21 June 2006 The German sectoral reporting module on transport and environment Walther Adler / Karl Schoer Federal Statistical Office Germany, Environmental-Economic Accounting

2. Overview • Goals • Methodology • Analysis • 2.1 Transport’s share on environmental pressures • 2.2 The environmental efficiency of transport • 2.3 Decomposition of change of the transport-related • environmental pressures • 2.4 Decomposition of change of freight transport • performance • 2.5 Econometric modelling of environmental-economic • effects of transport

3. Goals of the Project • Sectoral reporting modules: deepening (disaggregation of existing variables) and enhancing (inclusion of new variables) of the EEA-standard data-set in order to obtain more detailed and integrated accounting data on issues that are especially policy relevant. • Mobility is a important topic of sustainable development policy • There strong interlinkages between transport and other SD topics (need for integrated accounting data)

4. Methodology 1 • - Definition: motorised transportation of people and freight • over land and water, and in the air. • Integration: transport data a accounting satellite system • (same concepts, definitions, classifications) = mainly • reformatting of existing data • - Accounting concepts for transport: • Production perspective (who is the produces of the • transport service?): production of transport services • by resident units (homogeneous branches in a • NAMEA-type breakdown / mode of transport) • Use perspective (who is the user of the transport • service?): transport of goods for intermediate or final • use (in a NAMEA-type breakdown) on the economic • territory • Variables: Kilometres driven, passenger and freight transport • performance, transport related energy use, transport related air • emissions, land use (transport area)

5. Methodology 2 Calculation method (so far only production perspective): Example road transport: Starting point: stock of vehicles in a detailed breakdown by type and technical classes as well as by type of owner. The ownership classification is transformed into the classification of economic activities (production branches, private households) of the national accounts by using various data which are available in the National Accounts on asset stocks and burden distributions of mineral oil tax. Those stock data are the basis for assigning the flow information on kilometres covered, transport performance, energy and emissions to the economic activities.

10. Decomposition analysis of freight transport performance The freight transport performance itself can be depicted as a mathematical product of five factors: Scale effect: Change of GDP at constant prices. Degree of tertiarisation (service sector share): gross value added of material production to total production (VAM / GDP). Factual division of labour in the material production: relationship between total supply of material goods in monetary units to the gross value added of material goods production (TSM/VAM). Degree of refining of the transported goods: total weight of the transported goods is related to the total supply of material goods in monetary terms (TONS/TSM). Spatial differentiation of economic activities: freight transport performance to total freight volume in tonnes (FTP/TONS). .
