2. What is the fuel levy?
• Definition:
o It is a indirect excise tax
o paid at the pump on fuel sales
o at a rate of 255 cents per litre of petrol
o and a rate of 240 cents per litre of diesel (April 2015)
• Note – there is a difference between a tax, a charge and a toll
o A tax can be used for anything including general government expenditure
o A charge covers the cost of a specific service rendered
o A toll is used to pay for the specific infrastructure used

3. What is the fuel levy?... (2)
• Contribution:
o 5% of national tax revenue – R48,5 billion (2014 / 2015)
o 4th highest income stream

4. What is the fuel levy used for?
• Introduced in 1935, for the construction of national roads
o National Road Fund
o 3 pence per gallon
o £1,3 million in 1936
• Dedicated (ring-fenced) road use fund between 1983 and 1988 only
o Only a few countries currently have a dedicated road fund - America
• Since 1988 fuel levy used for:
o Construction and maintenance of roads
o Support of public transport…
o General government expenditure (also found internationally)
4
5. What is the fuel levy used for?... (2)
• The argument for using the fuel levy for general government expenditure programmes:
o The fuel levy is a tax
o High income stream for government
o Government will not have control over funds if fuel levy was ring-fenced
• If fuel levy was still ring-fenced:
o May generate insufficient funds
o May even lead to wasteful road constructions
o Hamper other important social development objectives
o NB - Good roads are not a substitute for poor schools, bad hospitals or poor public transport
“A physician would never think of expressing the general state of health of a patient by one single scalar indicator. He
knows that good lungs are not a substitute for bad kidneys… Why cannot the engineer / economist… also shift… to that
way of thinking.” – János Kornai, 1979

6. Is there a problem with the continuing use of
the fuel levy?
A. Becoming unproductive – less fuel is being sold per vehicle per annum
o Technological and societal trends
o The result is less income generated per vehicle
o But there is an increase in the registered vehicles population and total vehicle kilometres travelled
6
7. Productivity…
Period: 2000 – 2014
o Registered vehicle population grew by 68%
o Vehicle kilometre travelled grew by 45%
o Fuel sales grew by 40%
Period: 2015 - 2050
o Registered vehicle population grew by 479%
o Vehicle kilometre travelled grew by 262%
o Fuel sales grew by 139%
7
9. Is there a problem with the continuing use of
the fuel levy?... (2)
B. There is an argument / belief that vehicles don’t pay for actual road use (road use cost
≠ fuel levy paid)
o Cost that should be recouped:
Road construction and maintenance cost
Congestion cost
Environmental cost
Social cost
NB - We do not recover all these costs
9
10. 10
Is there a problem with the continuing use of
the fuel levy?... (3)
C. It is a regressive tax as opposed to progressive tax
o Thus increasing the tax will hurt poorer road users
D. Road construction cost increased
o driven by inflation and scarcity of resources
o and increased labour cost
E. Government needs to spend more on roads than generated from road charges
o R48,5 billion vs an estimated R100 billion road maintenance backlog (Wittman, 2010)
o Shortfall – funded from municipal rate taxes and transport grants (Freeman, 1982)
11. Problem isolated to South Africa?
• NO – other countries also experiencing a decline in fuel levy revenues
• America, European nations, New Zealand and Australia
• These nations actively engaged in looking at alternatives
• How can South Africa generate additional income to make up for the shortfall?
o Identify, explore and test a viable and operationally feasible alternative
o That addresses many of the problems associated with the current SA fuel levy
11
12. What transportation financing solutions exist?
• Traditional:
o Fuel taxes
o Sales taxes on fuel purchases
o Vehicle registration fees
o Traditional bond proceeds
o Tolls
o General fund expenditure – income taxes, sales taxes, property taxes
o Other – inspection fees, driver licence etc.
South Africa uses all these methods in some form, with the fuel levy contributing the highest
revenue from road users - about 80% (House of Commons, 2015)
12
13. What transportation financing solutions
exist?... (2)
• Non-traditional:
o Grant anticipation revenue vehicle – debt financing bond or lease
o Private activity bonds – debt financing for highway infrastructure
o Government credit assistance
o Public-private partnership – collaboration on a transportation project
o Other – traffic camera fees, emission fees, etc.
o Congestion and cordon pricing
o Kilometre-based road user charge
13
14. What transportation financing solutions
exist?... (3)
• Problem with methods (excluding kilometre-based and congestion pricing):
o Stimulate bad travel habits
A tax should change bad behaviour to good behaviour
o Don’t address problems associated with fuel levy
Small contributions to fund
14
15. What transportation financing solutions
exist?... (4)
• Two options remain:
o Congestion charge (cordon)
o Kilometre-based – our focus is on this
• It addresses the problems associated with current fuel levy system
1. Is not influenced by technological and societal trends
2. Can be a progressive tax
3. Generate more income to keep up with road construction costs
4. Is taxed for actual road use
15
16. 16
What transportation financing solutions
exist?... (5)
• Furthermore:
o It can supplement, complement and even in the future replace the fuel levy – provide sufficient income
o It is a policy sensitive alternative whereby if you change the tax, it impacts on road user’s behaviour
o It is in theory at least, relatively easy to implement
o It can inform road users of the road user costs they pay through an itemised road user charge monthly
bill
• So how will this work?....
o America – 26 states
o Europe – Switzerland, Austria, Germany, Hungary, Slovakia, the Czech republic and Poland
o France, Belgium and Russia
o New Zealand
o Developing countries?....
17. Kilometre-based road user charge system
• Many configurations – 11 key technical components
1. The purpose of implementation
o Reduce traffic congestion, excessive road wear , harmful emissions
2. Which vehicles to be charged
o Type, weight, number of axles, vehicle occupancy
3. Technological devices for measuring kilometres travelled
o Odometer, on-board device, GPS enabled, smartphone
4. Communication of the vehicle travel data

Welcome everyone
Thank you for choosing to attend my presentation. I promise I wont bore you. Although according to my undergrad classes I’m very good at that.
The research that I am going to show you today currently affects everyone of us in this room and will affect all of us in the future.
It is a hot topic at the moment both locally and internationally.
Many people have their own opinions on the subject
Ok, lets start….
I am currently busy with my PhD under guidance of Prof Stephan Krygsman focussing on transport infrastructure financing. I would like to show you today why I am researching this and where this will eventually lead.
Now, some of you will know what the fuel levy is, but some might have no idea. Effectively all of use pay a fuel levy when we fill up our car. So what is it?
Essentially we pay the fuel levy because we use the road.
Currently 285 cents for petrol and 270 cents for diesel.
Just note there is a difference …. You’ll understand the relevance of this as I go along
Subsequent to Personal income tax, VAT and company tax
Meaning the could use the tax you pay for using the road to supply school books to pupils, distribute TB medication or even pay for Nkandla.
Stock piling of road materials, rock and tar
We need to spend more on transport infrastructure than we can generate from the fuel levy. Government must use other funds.
Building of hospitals, schools.
For economic growth it doesn’t help that we have excellent roads but our hospitals and schools are falling apart. All infrastructure in a developing country must be maintained at the same level
A. This increase is due to technological trends:
Fuel efficiency
Electric and hybrid vehicles
Alternative fuels
And societal trends
Employees can work from home
Internet shopping
The registered vehicle population and vehicle kilometres travelled indicate the growth in demand for infrastructure
Fuel sales indicate the growth in resources to fund infrastructure (supply)
The demand exceeds supply which leads to congestion, thus a decline in infrastructure quality
Projecting the growth rates between 2014 and 2050:
Assumptions:
1500 electric / hybrid vehicle increase per year (10% increase per annum) (Dane, 2013)
Average vehicle kilometres travelled per vehicle decreasing by 1% per annum (Van Rensburg and Krygsman, 2015)
Bio-fuel - 2% share of fuel sales (SouthAfrica.info, 2013)
100% in 2000 (2378,3 litres per vehicle, per annum used)
81% in 2015 (1932,7 litres per vehicle, per annum used)
44% in 2050 (1022,9 litres per vehicle, per annum used)
Good news for you, bad news for government who has to supply the infrastructure
B. Cost that should be recouped:
Road construction and maintenance cost – to built infrastructure
Congestion cost – time delays / more fuel use / time value of money
Environmental cost – CO2 gas emissions
Social cost – cost to community – private cost and external
80% - figure from England
SA still unknown
Grant anticipation revenue vehicle – GARVEE – Used in America – issue debt for transportation projects using future funds. New Mexica 44 road example (forest of white crosses) – Government to state
Private activity bonds – debt financing for highway infrastructure – same as above – State gives to private entity – Parking garage
Government credit assistance – Government supplies loans for infrastructure projects – pay back the loan with interest
Public-private partnership – collaboration on a transportation project – Gautrain – Banks supplied funding with government
Other – traffic camera fees, emission fees, etc. – other taxes / fees / charges
That is why we have sin tax. Let you smoke and drink less.
We charge road users not per litre of fuel sold, but for every kilometre that they drive
My fuel levy this morning R2,8
22 km, 5l per 100 km @255 cents per litre
These include dedicated short-range communications (DSRC), global systems for mobile connections (GSM) and chip cards.
For using the system, we want to give something back to users:
Road use cost allocation model already proposed by Peter Freeman (1982)
Calculated propose charges by assuming an income of R54,6 billion in 2015
+ 5% operating cost of system
Fuel levy must still be paid – viable income source and easy to administrate
Otherwise we will lose income from fuel sales not for road use
Must still be used for general government expenditure
Proposed system simply complements the fuel levy to correct problems
