CRed carbon reduction 2 Energy Dialogue: Transport The Energy Review Historic Trends Technical Issues Fuel Efficiency New Fuels The Social Dimension How important is it? New Ideas Conclusions

CRed carbon reduction 3 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 The Energy Review Band G covers a broad range Base taxation directly on carbon emission? but much with a positive spin. Petrol Diesel Data from Vehicle Emissions Database

CRed carbon reduction 4 Historic 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 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?

CRed carbon reduction 5 Historic 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?

CRed carbon reduction 6 Private Motoring Components of Energy Demand in personal transport. Desire for mobility exceeded fuel efficiency improvements until Since 2000 energy consumption approximately in balance. Need to reduce further increases in mobility if CO 2 is to be reduced significantly. Personal mobility

CRed carbon reduction 9 Fuel 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% 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. Raising Awareness

CRed carbon reduction 10 Technical Issues: New Fuels Biofuels: one part of the solution in near term with Fuel Cells in longer Term?? 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” Biofuel Options Biogas Bioethanol (5% or 85%) Biodiesel (5% to 100%) Vegetable oil Benefit > Reduced CO2 and other emissions? Overall CO 2 emissions for different fuels/production methods/power trains. Based on CONCAWE/JRC/EUCAR results as adapted by Andy Taylor

CRed carbon reduction 12 Biodiesel Trials – Banham Poultry 2004 Despite reduced calorific value of biodiesel, fuel consumption remained the same First trials ever of fuel economy ‘on the road’ using biodiesel 8 Volvo FH12 Trucks: 5%, 20%, 35%, 50% biodiesel blends

CRed carbon reduction 13 Driver behaviour can affect performance Driver 2 uses 13.8% more fuel than driver 1 Biodiesel Trials – Banham Poultry Driver behaviour

CRed carbon reduction 14 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% Biodiesel Trials – Banham Poultry

CRed carbon reduction 15 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 – 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? Implications of Road Transport Fuel Obligation for 2010

CRed carbon reduction 16 Personal Mobility: Does Public Transport reduce car travel? UK D More use of car > more total distance travelled. Greater distance by train > 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.

CRed carbon reduction 18 Social Issues: Lift Sharing Our congested roads are full of empty seats The UK leader in lift sharing, Liftshare.com is based in Norfolk; Aim: CO2, Car Occupancy 2 52 million km shared each year. Car travel (2004 statistics): 679 billion passenger kilometres 398 billion vehicle kilometres Average occupancy Raising this to an average of 2 would save 9.9 Mtonnes CO 2. 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.

CRed carbon reduction 21 Conclusions Significant opportunities exist for reducing CO 2 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 Lao Tzu ( BC) Chinese Artist and Taoist philosopher "If you do not change direction, you may end up where you are heading." 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 CO 2 ?
