2Energy Dialogue Transport
- The Energy Review
- Historic Trends
- Technical Issues
- Fuel Efficiency
- New Fuels
- The Social Dimension
- How important is it?
- New Ideas
- Conclusions
3The Energy Review
- Just 3.2 of Review but Transport is 33.1 of
energy demand - Mostly what has been done
- Limited on future measures
- Has major omissions
but much with a positive spin.
Band G covers a broad range Base taxation
directly on carbon emission?
Data from Vehicle Emissions Database
4Historic Trends Personal Mobility
- Increase in personal mobility by 400 in 50
years - Mostly by car journeys
- Decline in bus travel (but trend now reversed )
- Nearly 50 increase in rail travel since
privatisation - represents a saving of 1.5 - 2 millions tonnes of
CO2 per annum compared to road.
If this travel is replacing road travel!!
Will investment in public transport necessarily
reduce car journeys?
5Historic Trends Freight
- Distance each tonne has travelled has increased
by - 223 since 1960
- 20 since 1990
- Is this increase in movement of freight conducive
to optimum economic growth, energy security, and
carbon reduction?
6Private Motoring
- Components of Energy Demand in personal
transport. - Desire for mobility exceeded fuel efficiency
improvements until 1990. - Since 2000 energy consumption approximately in
balance. - Need to reduce further increases in mobility if
CO2 is to be reduced significantly.
7Energy Efficiency Trends
Mean CO2 emissions voluntary targets will not
reach 140 g/km by 2008/09
Trends in car engine size
Consequence of increase in engine size is 2.9
Mtonnes extra of CO2. per annum.
Data from Transport Statistics 2005. Table 2005.
8Size of Car Engines in Market 2006
Percentage of models available compared to social
desire. -ve means less models on market
than people intending to buy.
Size of Choice according to survey

the Impact of Graduated Vehicle Excise Duty
9Fuel Consumption and Driver Behaviour
- Car 5 door Toyota Yaris
- Real performance is best at 50 mph. Saves up
to 15 in fuel consumption cf 70 mph. - Driver behaviour at low to moderate speeds can
affect consumption by up to 10
Raising Awareness
- A small car emits equivalent of 1 party balloon
every 60m. - Driving just 1.6 miles emits as much carbon
dioxide as heating an old persons room for 1 hour.
10Technical Issues New Fuels
- Biofuels one part of the solution in near term
with Fuel Cells in longer Term?? -
- Biofuel Options
- Biogas
- Bioethanol (5 or 85)
- Biodiesel (5 to 100)
- Vegetable oil
- Benefit
- gt Reduced CO2 and other emissions?
Depending on the pathway, biofuels can have a
major impact in reducing CO2 from
transport.However, other studies give
differing results and clarity and robustness of
methodolgy is needed including Real Road Tests
Overall CO2 emissions for different
fuels/production methods/power trains. Based on
CONCAWE/JRC/EUCAR results as adapted by Andy
Taylor
11Launch of BioEthanol in UK Norwich 15th March
2006
Planning is needed both for vehicles and
infrastructure
12Biodiesel Trials Banham Poultry 2004
First trials ever of fuel economy on the road
using biodiesel 8 Volvo FH12 Trucks 5, 20,
35, 50 biodiesel blends
- Despite reduced calorific value of biodiesel,
- fuel consumption remained the same
13Biodiesel Trials Banham Poultry
Driver behaviour
- Driver behaviour can affect performance
- Driver 2 uses 13.8 more fuel than driver 1
14Biodiesel Trials Banham Poultry
- Trials demonstrated other benefits compounding to
60 saving - Using 50 uvo biodiesel (40 saving)
- Advanced driver training (15 saving)
cumulative 49 - Better route/load planning (10 saving)
cumulative 54 - More fuel-efficient trucks (10 saving)
cumulative 59 -
Total CO2 saving 59 - However
- Widespread availability of biodiesel at this
concentration and new trucks will take time - Other actions could be taken in shorter time
scale - Advanced driver training (15 saving)
- Better route/load planning (10 saving)
- Total CO2 saving 24
15Implications of Road Transport Fuel Obligation
for 2010
- In UK it is 5 substitution of biofuels by
volume. Should it be 5 by energy? - Will the buy out money necessarily end up
promoting UK projects as with Renewable
Obligation? - Significant quantities of wheat are exported
which could be used for bioethanol. - Land Area required for 5 by volume
- 10000 12000 sq km (similar to NFU figure of
1.2 Mha) - or 4-5 of total land area of UK.
- area of Norfolk, Suffolk, and part of
Cambridgeshire combined - Opportunities for use of co-products- animal
feed/power generation - What happens if RTFO is increased further? Is
land area requirement sustainable?
16Personal Mobility Does Public Transport reduce
car travel?
More use of car gt more total distance
travelled. Greater distance by train gt greater
use of car. Compare UK with Germany switch
UK car journeys to public transport at German
levels. saving by train
1.01 M tonnes
saving by bus 0.74 M
tonnes Reducing mobility desire 9.22
M tonnes
Suggests overriding issue is increased desire for
mobility rather than significant switching of
mode of transport.
17Investment in Public Transport
- Invest in Public Transport and get people out of
their cars? - Norwich Orbital bus scheme - 1.2 million
- Links railway station, hospital, University, City
Centre with places near Ring Road. - Not that popular yet. People still using their
cars. Fare 1.65 return car park charges
at hospital often considerably more.
B
- Smart Dynamic Bus Routing?
- Bus Service A gt B
- People at C not served
- Divert route via C
- increased journey times less popular with A gt B,
particularly if people only occasionally get on
at C. - Dynamic Routing on demand
- extension of Trinidad Route Bus
System
C
- Mobile phone SMS
- Intelligent bus stops

18Social Issues Lift SharingOur congested
roads are full of empty seats
- Car travel (2004 statistics)
- 679 billion passenger kilometres
- 398 billion vehicle kilometres
- Average occupancy 1.71.
- Raising this to an average of 2 would save
- 9.9 Mtonnes CO2.
Lift sharing/car pooling is very cost effective,
can help combat social exclusion, and enhance the
effectiveness of public transport. Increasing
average car occupancy is a very cheap way of
saving CO2 and reducing car use.
The UK leader in lift sharing, Liftshare.com is
based in Norfolk Aim CO2, Car Occupancy 2 52
million km shared each year.
19Social Issues First car share club in East
Anglia
However, some research of Cambridge scheme by
Prof. Crawford Brown suggests that much of use is
additional use not replacement use.

20Providing Public with more information
- Impact of carbon emissions
- Petrol receipt from Denmark
- Individuals often go for budget airlines for the
cheap weekend break in Europe. Is this
rational? - e.g. Paris for weekend break

21Conclusions
- Significant opportunities exist for reducing CO2
using biofuels. - Government needs clearer statements on its
commitments e.g.RTFO. - Why not a requirement of 5 by energy content?
- Where will buy out money go?
- Will it promote industry in UK?
- Land requirements in post 2010 ideas from
increased RTFO? - Issues of fuel efficiency need addressing more
effectively - Reverse trend towards large engine cars
- Revisit the banding system and related taxation
- Social Dimension must not be overlooked.
- Better education/awareness - driver behaviour.
- Address issue of continual increases in desire
for mobility. - Could provide more rapid and cheaper method to
reduce CO2?
