COST 355 WG1freight transport, energy GHG
Christophe Rizet (INRETS DEST)

Freight transport, energy GHG
  • Transport sector a significant contributor to
    energy consumption and GHG emissions, (23 of CO2
    emissions from fossil fuel combustion) It is
    98 dependent on oil
  • A significant behavioral change in transport
    sector is necessary, to account for shortage in
    oil and for climate.
  • On the other hand, Freight transport is also a
    key factor in economic prosperity
  • There are significant reservoirs of energy
    efficiency that might allow economies to enjoy
    the same level of wealth with lower overall
    levels of energy use in freight.

Freight transport, energy GHG
  • A clear need for better tracking and monitoring
    freight transport energy performance across
    modes, and activities.
  • In this WG1, we tried different approaches for
    this monitoring and assessment of freight
    transport-sector energy performance.
  • Most of these approaches have been presented
    before How do they compare ?

4
Different approaches to monitor analyse freight
transport energy
  • observe and quantify energy consumption, the
    corresponding transport unit and the
    explanatory variables
  • And anlyse the results
  • The different statistical units observed, (cf
    previous presentation)
  • a vehicle or a fleet
  • a shipper
  • A whole supply chain
  • A geographical unit, town, country,
  • Last mile

5
1) Vehicle or fleet approach advantages
limits
  • Advantages
  • Such a quantification is the basis for a
    bottom-up approach
  • It is precise, well established in Europe for HGV
    and indicators are easy to compare (between
    countries, vehicle types, business or Cies)
  • It is necessary for a detailed assessment of
    policy measures aiming at the vehicle performance
  • It could be improved with GPS
  • Limits
  • Difficult to link the transport to the economy
    nothing on transport chains or on shippers
    logistical choice
  • Transport energy consumption does not only depend
    on the vehicle performance

6
2) Shipper approach
  • DLR shipper surveys
  • Qualitative Survey transport issues in
    production decisions Dynamics of production
    changes Mode use and reasons
  • Quantitative survey Supplier / customer
    structure, Relationship to shippers, Current
    transport demand Transport requirements)
  • INRETS shipper surveys
  • Link freight transport to the shippers a large
    description of the shipper, its logistics and the
    links with its clients
  • Trace the transport chain 3 shipments per
    shipper are traced from the shipper up to the
    consignee the different legs of the chain, the
    vehicles, etc..
  • Univ Paris IX transport mitigation of a Company
    (optimization of the location of the
    establishments)

7
2) Shipper transport chain approach
advantages limits
  • Advantages
  • A good link to logistical choices (behaviour of
    companies) mode choices
  • Tracking of transport chains (parcels)
  • Spatial pattern of supply
  • Other Shipper approach US commodity flow survey
  • Limits
  • High cost of survey (collecting the data)
  • Heavy work for setting the data base
  • Only first step of supply chains (of the
    customers or the sourcing)

8
The supply chain approach
  • Main objectives Link the different steps of
    transport, from raw material up to the consumer
    home.
  • A global vue of spatial organisation of economy
  • energy impact of globalisation
  • energy impact of human density
  • Efficiency of different types of retailers
  • Quantify the weight of transport in the products

9
3) Supply chain approach advantages limits
  • Advantages
  • Impact of spatial organisation of the production
    weight of transport in energy consumption
  • Limits
  • For some products, transport is not important in
    the LCA
  • Increased transport versus economy of scale in
    making
  • Cost of the survey/study a qualitative
    approach.

10
4 Last Mile approach
  • Focuse on the urban part of the SC, where the
    constraints of sustainability are the highest,
  • Where the cost of the entire SC are also high
  • This approach is Policy Oriented research of
    innovating system, mainly to improve good
    distribution, urban traffic, congestion, energy
    consumption and emissions

11
4 Last mile approach advantages limits
  • The monitoring of the last mile is difficult
    because it results of different actors behaviour
    (households, operators and public authorities).
  • During the last decade, many organisational
    changes have been tempted and observed concerning
    the infrastructure and the vehicles which
    contributed to changing behaviours.
  • These experiments are shared over Europe

12
5 Modelling approach
  • international models some relations between
    freight transport and the differential in
    production costs but a big problem of data.
  • Interurban freight models are usefull to analyse
    the relation between economic growth (GDP) and
    freight transprot growth. The de/coupling
    results of many elements (average loading factor,
    land use, origin of sourcing) whose weights
    differ among countries
  • Urban model Freturb is an example of
    integration of survey analysis modelling. It
    gives accurate results for the cities years
    where the data are available and some results
    start to be generalised

13
Modelling approach
  • The modelling approach gives a broader view of
    energy consumed within a town, a country or in
    international relations.
  • Necessary to link the output (energy GHG) to
    the input variables (policies) which is necessary
    to asses the impact of different policy options
    or different scenarii on energy consumption.
  • Models, as well as the data needed to feed them,
    should be harmonised in Europe and worldwide.

14
GHG abatement measures for the freight transport
sector
  • A reduction of energy consumed in freight
    transport sector, without reducing the economic
    activity, can be obtained by
  • A decrease in the ratio between the GDP and the
    freight transport activity expressed in tkm (i.e.
    decoupling),
  • A decrease in the use of the less energy
    efficient means of transport (modal shift)
  • An increase in energy efficiency of each mean
    (decrease of goe/tkm by transport mean)
  • A decrease in the CO2 emitted per litter of fuel
    increase the share of bio fuels and non fossil
    electricity (decrease in CO2/gep)

15
A variety of tools are available for CO2
abatement policies in Freight transport
  • Taxes like carbon or fossil fuel taxes or
    tradable emission quotas extended to the freight
    transport sector
  • Public investments or subsidies for modal shift
    in railways, waterways and low emission modes
  • For increasing the energy efficiency of vehicles
    Setting rules (or agreements) on vehicles per
    km emissions, and disseminating technological
    fuel efficiency improvements.
  • For the carbon intensity of fuels funding
    research in bio fuels and hydrogen and shift
    toward electricity.

16
Assessing CO2 abatement policies
  • No transportation project is done for energy or
    GHG reductions alone. Without accounting for full
    project benefits, incremental costs may appear
    high.
  • An issue is then how to estimate and weight the
    different project benefits? (GHG, air quality,
    health, congestion, economic development, etc.)
  • This would help to estimate a marginal CO2
    abatement cost (/t of CO2) in Europe.

17
GHG abatement policies for Freight Madrid
meeting
  • Countries have not yet decided their policies for
    freight.
  • The different possibilities are not clearly
    considered and compared In Madrid, we heard very
    different approaches among countries.
  • There is a need for an harmonization of policies,
    and so an harmonization of monitoring tools
  • Including harmonization of tools for freight and
    passengers
