Definition or understanding of tradable pollutionpermits (a limit placed on firms carbon emissionsthrough issue of permits / permits can bepurchased and sold / fines if firms exceed limitwithout buying permits) (1+1 marks).
•
Data reference: e.g. Australian governmentintends to reduce carbon emissions by 5% by 2020/ Australia accounts for 1.5% of greenhouse gasemissions (1 mark) Benefits of tradable pollution permits to reducepollution (2+2+2+2 or 3+3+2 marks): NB: Do not award for discussion of benefits inreducing air pollution and impact of globalwarming. The focus has to be on the merits anddemerits of the system of tradable permits.
•
A market created for buying and selling carbonpermits / use of price mechanism to internaliseexternal costs / the best way to reduce carbonemissions.
•
This may be shown through a relevant externalitydiagram / where external costs are internalisedthrough trade in carbon permits / somedevelopment e.g. reduce welfare loss or identifyrevenue from sale of carbon permit (1+1+1marks).
•
Use of demand and supply diagram / depicting adecrease in supply of permits and its subsequentincrease in price of permits (1+1 marks)
•
Australia is one of the world’s largest carbonpolluters per head of population / so the scheme isjustified to help reduce global emissions.
•
The Australian emissions trading scheme is similarto the EU and so could help create a global scheme/ especially as China and South Korea showinterest in setting up one.
•
Government can raise funds by selling somepollution permits / revenue can be used to reduceeffects of pollution / subsidise cleaner technology /compensate victims.
•
Firms have an incentive to invest in cleantechnology / then sell excess permits to other firms/ or bank surplus permits for future years.
•
The heavy polluting firms are disadvantaged byexperiencing higher production costs from buyingextra permits/ whereas the cleaner firms are at anadvantage with relatively lower production costsfrom selling surplus permits.
•
Data bias could exist as Anglo AmericanCorporation may be exaggerating theunemployment effects of an emissions tradingscheme. Evaluation = 6 marks
Consideration of the limitations of tradablepollution permits for reducing pollution or theirdisadvantages (2+2+2 or 3+3 marks):
•
Extract 2 suggests huge increase in costs formining industry of A$25 billion by 2020 / manyjobs directly and indirectly at risk / development ofthis point e.g. related industries such as miningtools industry or manufacturing industry.
•
Extract 2 indicates that Australia only accounts for1.5 per cent of global carbon emissions / not muchpoint setting up the scheme compared to the costfor mining companies.
•
Extract 2 suggests a decrease in mininginvestment projects / development of this pointe.g. reduce Australia’s ability to meet futureenergy needs.
•
Little incentive for firms to reduce pollution since /94.5 per cent of permits issued for free and sogovernment failure / heavy polluters can purchasesurplus permits from other firms rather than investin expensive clean technology.
•
Disputes arise over allocation of permits / possiblebarriers to entry.
•
A cost to the government of monitoring andenforcing carbon pollution emissions rules.
•
The valuation of pollution permits may be too riskyto leave to the market.
•
Problem that most countries in the world are notpart of an emissions trading scheme especially US(apart from California).
•
Other schemes might be more effective in reducingcarbon emissions e.g. carbon offsetting orrenewable energy certificates.
