Global trend of environmental degradation

increase of the amount of CO2 in the atmosphere

acceleration of global warming

destruction of the ozone layer ・・・

We need to preserve the environment!

We need a certain regulation.

Main characteristic of environmental issue

External diseconomyAction of a certain economic unit that induces a loss to other economic units, without performing payment or compensating the expense.

PPP (polluter-pays principle)The idea that whoever causes pollution is responsible for the cost of repairing any damage.

4

Two kinds of regulations

Direct regulation (command and control) This has been achieved by applying direct

regulatory controls on industry, for instance by specifying allowable levels of pollution.

The basis of the regulatory system is that the polluter has little choice - they comply with the standard imposed or face penalties.

This system may be the most appropriate for controlling particularly dangerous pollutants.

5

Two kinds of regulations (2)

Economic means (economic instruments) This regulation promises to transform the

pattern of pollution control. This aim to control pollution by harnessing

the power of market incentives, offer a more cost-effective, flexible and dynamic form of regulation than conventional measures.

6

Direct regulation

Merits Immediate effect

Demerits Administration cost is very huge Administration cannot identify discharge

curtailment of expense between companies Causal relationship is complicated Extent of the impact is too wide

7

Economic means

Merits PPP is reflected Use of price mechanism is effective Efficient distribution of resources is possible Applicable from prevention measures to

penal regulations Demerits

A setup of the optimal tax rates is difficult The rate of a low income earner's expense

burden is large

8

Kind of Economics Means

Transferable (tradable) Permit System Fiscal measures Measures for older vehicles Emission charges Quota system on car ownership Road pricing (licence)

9

Transferable Permits (TP) System

10

What is the TP system?

TP is not a new concept (it has been used in fisheries, in the fields of construction and water pollution).

Variety of instruments: introduction of flexibility into traditional regulation, organization of competitive markets for permits…

11

What is the TP system? (2)

These various means have in common: Quantified physical constraints

(obligations, permits, credits, rights) Permission granted to the agents to

transfer these quotas between Activities Products Places (offsetting) Periods of time (banking) Other agents (trading)

12

Features of TP appropriate for the transport sector

More likely to achieve a quantitative objective than taxation.

If the price-elasticity of demand is low in the short term or medium term, a TP system is more appropriate.

It allows flexible implementation of control of policy and can be used to target local and regional problems arising from the transportation activities.

13

Features of TP appropriate for the transport sector (2)

In political terms, systems where permits are allocated free of charge may be seen as a means of avoiding an additional tax, e.g.. High fuel duties in Europe, this can enhance the acceptability of the new environment.

14

Important points for effective TP

The heterogeneity of the agents involved in the system. Marginal costs of pollution abatement must be

sufficiently different for agents allowing profits to be made by the exchange of permits and thus letting the market function effectively.

Clarity: the physical basis is clearly defined Simplicity: for transactions Pragmatism: the program should be able to

evolve

15

Main arguments against the use of TP

Cost of administration over a large number of mobile sources

Transaction cost of transferability.

16

Potential for Implementation

Unitary vehicle emissions Fuel standard Car ownership Car use Land-use

Case study: Ecopoint program in Austria

18

Background

NS route Italy – Germany Major link between

Eastern Europe and Western Europe

Ecologically fragile Alpine valleys

Exhaust emissions cannot readily escape

Highway noise is intensified

NOX are 3 times higher than on a plain with similar traffic volumes

Objectives of the Ecopoint Program

Austria negotiated an agreement with the European Union concerning trucks passing through Austria.

The objectives were to reduce atmospheric pollution (NOX) to 60% of its level in 1991 after 12 years, and to reduce the noise.

20

The Ecopoint Program

Concerns the heavy goods vehicles (HGV) that pass through Austria, originating from all EU Member States and some other countries.

Each vehicle has a Conformity of Production document (COP) which states its level of NOX emissions, and the number of Ecopoints required to travel through Austria (October 1, 1990). 1 Ecopoint = 1g of NOX/kWh

21

The Ecopoint Program (continued)

Ecopoints are distributed annually by the European Commission among the Member States, which in turn redistribute them among their hauliers.

The unused Ecopoints are transferred through an administrative process.

The Ecopoints are deducted using an electronic system (Ecotags, overhead electronic readers).

22

Results: costs

Interoperable electronic road charging systems targeting trucks exist already, or are being set up in several European countries.

the costs will be minimal once these systems are already working

23

Results: benefits

The number of Ecopoints used by trucks has declined more swiftly than the target value laid down in the agreement. The program may have accelerated the technology shift.

Percentage of trucks paying a certain number of Ecopoints

24

Results: shortcomings

Insufficient coverage of pollution sources Trucks going to Austria or coming from Austria Light-duty vehicles and buses

Lack of incentive to use even cleaner trucks Because the number of through trips cannot exceed

108% of the number in 1991 (the “108% clause”) Too comprehensive measure for addressing

the preservation of Alpine valleys The system targets entire Austria, so the traffic may

increase in the Alpine valleys as long as it decreases in plains

25

Conclusions

It is technically possible to apply a quota-based system of permits to mobile sources within a defined area, at an acceptable financial cost.

The points of entry and exit should be few and easily controllable (trade-off with the size of the area).

The transfer of quotas between hauliers could have been introduced, to reduce the total cost of the scheme.
