Passenger transport demand - outlook from WBCSD
According to the IEA/SMP model projections, the growth in the volume of passenger transport will not be decoupled from the economical growth significantly. This will be true for the whole pan-European region. Transport growth will be only marginally lower than GDP growth between 2000 and 2050. During the outlook period passenger transport demand will grow on 5-11% slower than GDP in for Eastern Europe in; 3-7% slower for Former Soviet Union and 3-6% in OECD -Europe in 2020.
The share of rail transport is predicted to be stable in Eastern Europe accounting for about 10%, it is expected to grow in OECD-Europe from 4,6% in 2000 to 5,7 % in 2050 and it is expected to decline in FSU from 17,7% to 15,3 %. The share of the car passenger transport is expected to decline in OECD-Europe and Eastern Europe by 13% and grow by about 15% in FSU. The share of air transport is expected to grow in all pan European region by factor 2,3 in OECD-Europe, 2,6 in FSU and by factor 4,7 in Eastern Europe
K: Is there in Europe a trend of decoupling of passenger transport demand from economic growth?
Trends in passenger transport demand and GDP in Pan-European region
Note: No individual countries are presented
Data provenance info is missing.
The projections made by the IEM/SMP model estimate that passenger transport demand will increase in whole pan European region from 2000 to 2050, thereby making it increasingly difficult to stabilise or reduce the environmental impacts of transport. The growth is expected in all European sub-regions (Eastern Europe, Former Soviet Union and OECD-Europe). In the reference case projections, total passenger transport demand increases between 2000 and 2050 by a factor of nearly 1,5 in OECD-Europe, 2,5 in Eastern Europe and 2,7 in Former Soviet Union (FSU).
Transport demand per capita will also grow and will change between 2000 to 2050 from about 12600 km to about 20230 km for OECD-Europe; from about 6900 km to about 20400 km in Eastern Europe and from about 5600 km to about 15200 km for Former Soviet Union.
The tendency of the current underlying factor for growth passenger transport demand will remain similar in the future. This factor is related with the growth in incomes coupled with a tendency to spend more or less the same share of disposable income on transport. Additional income therefore means additional travel budget, which allows more frequent, faster, farther and more luxurious traveling.
Overall growth in passenger transport demand is expected to be similar to that of GDP. For OECD-Europe transport growth is predicted to be marginally lower than GDP growth between 2005 and 2015 in OECD-Europe. It is expected to be 3% in 2015, grow to 6% and fall to 3% again in 2035. For the Eastern Europe transport growth is estimated to be lower than GDP in 11% in 2005, 5% in 2030 and 9% in 2040. Similar trend is predicted for FSU countries with the 6% slower than GPD transport growth in 2005, 3% in 2020 and 7% in 2050.
Thus the achievement of the stated in the 6th EU Environmental programme objective of significant decoupling of transport demand from GDP is not expected under the reference case scenario. The objective of EECCA strategy to use transport demand side management is also unlikely to be achieved.
S: Is there in Europe a trend of reduction of car passenger transport and increase of rail passenger transport in total inland passenger transport in relative to other modes?
Projections of the passenger transport demand by mode
Note: No individual countries are presented
Data provenance info is missing.
With regard to the modal split of transport, no major technological substitution is expected over the 2000 - 2050 horizon.
The projected trends for the car passenger demand are different for European sub regions Expected increasing wealth among citizens give more people the option to buy a car and use the added flexibility that it provides. Only in dense urban centers and for longer distances can public transport compete in terms of travel time.
In the Former Soviet Union the total passenger demand is expected to rise by 167% with an increase of private care travel by almost 260 %. Reasons for such growth are similar to those in
In OECD Europe the predicted increase of total passenger transport demand from 2000 to 2050 is 45,3%, whereas the car passenger demand increases only by 14,7 % as the private automobile market is already saturated.
At the same time for the outlook period the share of the car passenger transport is expected to decline in OECD-Europe from 63% to 50 % and in
This outlook indicates that it is unlikely that the objectives of the EECCA Environmental Strategy as to development more sustainable transport systems including public transport will be achieved unless strong measures for sustainable transportation and behavior change will be introduced and enforced.
Pessimistic prognoses are suggested as well for the achievement of the objective of the Common Transport Policy of maintaining the 1998 modal shares. The outlook shows that that if currents rates of growth continue, air will surpass rail and busses and coaches and become the second most important mode of passenger transport after cars. For example, share of the total is expected to increase from 13% in 2000 to 31% in 2050 OECD-Europe, from 7 % to 33 % in
To address adverse effects of a growing air transport 7th FPR will place a stronger orientation towards 'greenings' air transport with a greater focus on climate change as one of the main priority issues. Higher priority must be given to EU aeronautics research aimed at actually reducing the negative impacts of air transport on climate change.
The technological developments of the air transport were discussed in the White paper 'European transport policy for 2010:time to decide' and the Report 'the Future of European Aerospace: A shared vision for 2020'. These documents suggest that medium-capacity aircrafts can be expected to continue to predominate on most intra-Community flights. By contrast, on high-density long-haul flights many airlines will probably opt for very large aircrafts. The Airbus A 380 is the first example of what the next generation of aircraft will probably look like: large carriers capable of transforming more passengers. The aviation industry is preparing for this.
The developments of the air transport in the Former Soviet Union are not excepted to be as fast as in the rest of
According to the IEA/SMP outlook the objective of the European transport policy which aimed to increase railway passenger share from 6 to 10% by 2020 is unlikely to be achieved. It is expected that in OECD-Europe the share of the rail passenger transport will increase from 4.6 in 2000 to only 5,0% in 2020 and 5,7% in 2050. (May be to include that more efforts should be made in order to achieve this objective). The rail passenger transport share is expected to be stable at the level of about 10% during the whole outlook period in
The shares of public transport (busses, minibuses) are predicted to decrease in the whole pan-European region: in OECD Europe from 15% in 2000 to 10% in 2050; in

Policy context and targets
Pan-European policy context
The large number of non binding policy instruments have been developed under fora such as Environment for Europe process, the European Council of Ministers of Transport (ECMT) and the UNECE/WTO Transport, Health and Environment Pan-European Programme (The PEP). The PEP was set up to address the key challenges to achieve more sustainable transport patterns and a closer integration of environmental and health concerns into transport policies.
EU policy context
The EU has set itself the objective to reduce the link between economic growth and passenger transport demand ('decoupling') in order to achieve more sustainable transport.
Reducing the link between transport growth and GDP is a central theme in EU transport policy for reducing the negative impacts from transport:
- The objective of decoupling passenger transport demand from GDP was first mentioned in the Transport & Environment (T&E) integration strategy that was adopted by the Council of ministers in Helsinki. Here, the expected growth in transport demand was named as an area where urgent action was needed. In the sustainable development strategy that was adopted by the European Council in Gothenburg, the objective of decoupling is set in order to reduce congestion and other negative side-effects of transport.
- In the review of the T&E integration strategy in 2001 and 2002, the Council reaffirmed the objective of reducing the link between the growth of transport and GDP.
- In the Sixth Community Environmental Action Programme, decoupling of economic growth and transport demand is named as one of the key objectives in order to deal with climate change and to alleviate health impacts from transport in urban areas.
Shifting transport from road to rail is an important strategic element in the EU transport policy. The objective was first formulated in the Sustainable Development Strategy (SDS). In the review of the T&E integration strategy in 2001 and 2002, the Council states that the modal split should remain stable for at least the next ten years, even with further traffic growth.
In the White Paper on the Common Transport Policy (CTP) "European Transport Policy for 2010: Time to Decide", the modal shift is central and the Commission proposes measures aimed at the modal shift.
The White Paper on the Common Transport Policy also says that common transport policy alone will not provide all the answers. It must be part of an overall strategy integrating sustainable development, to include: a) economic policy and changes in the production process that influence demand for transport; b) land-use planning policy and in particular town planning; c) social and education policy; d) urban transport policy; e) budgetary and fiscal policy to, to link the internalisation of external, and especial environmental, costs with competition of trans-European network; f) competition policy, to ensure, in line with the objectives of high-quality public services, and in particularly in rail sector, that the opening-up of market is not harmed by the dominant companies already present on market; g) research policy for transport in Europe.
The European Neighbourhood Policy stressed that generating more trade and tourism between the Union and its neighbours, requires efficient, multimodal and sustainable transport systems. EU should develop an Actions plan for cooperation with its neighbors to improve the physical transport networks connecting the Union with neighboring countries, to step up aviation relations with partner countries with the aim to open up markets and to co-operate on safety and security issues. The Action Plans will also contain specific provisions to address the vulnerability of transport networks and services vis-A-vis terrorist attacks. The highest attention will be paid to enhance the security of air and maritime transport.
EECCA policy context
EECCA Environmental Strategy recognizes the need to incorporate environmental concerns into transport policies and sets this action as one of the Strategy objectives.
One of the actions selected by THE PEP is 'demand side management and modal shift and with special attention to the needs of the countries of Eastern Europe, Caucasus and Central Asia (EECCA) and of South-Eastern Europe, as well as issues related to ecologically particularly sensitive areas'.

Methodology for indicator calculation
To obtain outlook of decoupling of passenger demand from economic growth, the trends from 2000 to 2050 of volume of passenger transport in passenger-km and GDP in billion USD are compared and shown separately on a graph. Relative decoupling occurs when passenger transport demand grows at a rate below that of GDP. Absolute decoupling occurs when passenger transport demand falls while GDP rises or remains constant.
The projections for the volume of passenger transport and GDP are taken from the IEA/WBCSD Sustainable Mobility Project (SMP) model. To cover pan-European region these data were extracted from the publicly available (version 1.6) for the following geographical areas: OECD Europe, Eastern Europe, and Former Soviet Union.
Outlook for the modal split share for passenger transport in total inland transport was extracted from the same model.
Overview of the SMP Spreadsheet Model(The flowchart on the page 4 of the IEA/SMP model spreadsheet privides an example of the logic behind the model on the basis of light-duty vehicles(e.g. automobiles)).
The IEA/SMP Transport Spreadsheet Model is designed to handle all transport modes and most vehicle types. It produces projections of vehicle stocks, travel, energy use and other indicators through 2050 for a reference case and for various policy cases and scenarios. It is designed to have some technology-oriented detail and to allow fairly detailed bottom-up modeling. The SMP spreadsheet model 1.60 is the most recent version and is available for a more detailed inspection (and use, though no user guide has been prepared and there are no plans, at this time, of providing on-going usersupport for the model. A very basic outline of how to use the model is provided in the first sheet of the model spreadsheet).
The model does not include any representation of economic relationships (e.g., elasticities) nor does it track costs. Rather, it is an "accounting" model, anchored by the "ASIF" identity:
- Activity (passenger and freight travel)
- Structure (travel shares by mode and vehicle type)
- Intensity (fuel efficiency)
- Fuel type = fuel use by fuel type (and CO2 emissions per unit fuel use).
The modes, technologies, fuels, regions and basic variables are included in the spreadsheet model. Not all technologies or variables are covered for all modes. Apart from energy use, the model tracks emissions of CO2, and CO2-equivalent GHG emissions (from vehicles as well as upstream), PM, NOx, HC, CO and Pb. Projections of safety (fatalities and injuries) are also incorporated.
The most detailed segment of the model covers light-duty vehicles. The flow chart on the page 4 of the Model Documentation provides an overview of the key linkages in the light-duty vehicle section of the model. For other passenger modes (such as buses, 2-wheelers), the approach is similar, however there is no stock model. Stocks are projected directly; vehicle sales needed to achieve these stocks is not currently tracked.

Key model assumptions for the reference case The reference case projects one possible set of future conditions, based on recent trends in various important indicators and other variables. Adjustments are made for expected deviations from recent trends due to factors such as existing policies, population projections, income projections and expected availability of new technologies. Expectations for other future changes in trends, such as saturations in vehicle ownership, are also incorporated.
In general, no major new policies are assumed to be implemented beyond those already implemented in 2003. An exception to this is where there is clear evidence of what might be called "policy trajectories" - future policy actions that are either explicit or implicit in other trends. For example, a clear trend is emerging in the developing world to adopt vehicle emissions standards of a form similar to those already implemented in OECD countries. It is assumed that this "policy trajectory" will continue in the future. In contrast, no such policy trajectory is evident for reduced light-duty vehicle (LDV) fuel consumption; we therefore only incorporate existing fuel consumption programmes through the year they currently end; we assume a return after that date to historical (non-policy-driven) trends in fuel consumption.
In general, the model tried to avoid introducing significant changes in trends after 2030. We run the trends assumed to exist in 2030 out to 2050 in order to see the net effects and directions in that latter year of actions and events that often occurred years earlier.

Uncertainties related to indicator calculation
All data should be based on movements on national territory, regardless of the nationality of the vehicle. It is unknown what the assumptions are regarding movement of the transport when the assigned regions.
To answer the question of whether passenger demand is being decoupled from economic growth we need to look at the intensity of passenger transport relative to changes in real GDP. A reduction in intensity should signal relative decoupling. This has some implications on the interpretation one makes of the observed intensity values. GDP in constant prices simply takes away the effect of price increases from year X to year Y but it does not guarantee that GDP in year X for country A is comparable to GDP in country B (as year X is the result of price increases from previous years etc). Therefore, cross-country comparisons of transport intensities based on real GDP may be relevant for trends (i.e. growth/changes over time) but not for comparing intensity values in specific years. If we are interested in knowing whether passenger transport intensity is higher in one country than in another, GDP should ideally be measured in purchasing power parities. These are currency conversion rates that both convert to a common currency and equalise the purchasing power of different currencies (i.e. they eliminate the differences in price levels between countries).
It is arguable, however, whether purchasing power parities are the best currency unit for time-series analysis. One way to avoid such problems is to use population instead of GDP. This would in principle be appropriate for the comparison of intensities between countries as well as for looking at trends over time. It seems also more equitable. To respond to the question of whether or not we are decoupling transport demand from economic activity (i.e. looking at growth rates over time) we would still need to use GDP.
Uncertainties related to IEA/SMP transport modelThe model does not include any representation of economic relationships (e.g.,
elasticities) nor does it track costs. The IEA has a cost-optimization model capable of this, the ETP model, but this model was not employed in the SMP's work due to its lack of transparency and its complexity.
Uncertainties related to use of outlooksto be filled
Data sets uncertaintyThe table below provides a simplified picture of what types of variables and the level of
detail modelled for each major transport mode in the IEA/SMP transport spreadsheet model. As can be seen in the next table, there is a range of coverage by mode, as well as variations in the quality of the data available (indicated by x or i). In general, there is better data available for light-duty vehicles than for other modes, though for non-OECD regions most data is quite poor, except for aggregate estimates of transport energy consumption. New vehicle characteristics are only tracked for light-duty vehicles; existing stock is used as the basic vehicle indicator for all other modes.

The relevance of the modal split policy for environmental impact of passenger transport arises from differences in environmental performance (resource consumption, greenhouse gas emissions, pollutant and noise emissions, land consumption, accidents etc.) of transport modes. These differences are becoming smaller on a passenger-km basis, which makes it increasingly difficult to determine the direct and future overall environmental effects of modal shifting. The total environmental effect of modal shifting can in fact only be determined on a case-by-case basis, where local circumstances and specific local environmental effects can be taken into account (e.g. transport in urban areas or over long distances).
