Extra Carbon Flows from Burning Fossil Fuels

CO2 levels have increased sharply in the 20th

century. (From 280 ppm to 380 ppm)

Greenhouse Gas Levels

• Greenhouse gases exist in minute concentrations but have an essential role supporting life.

• In the absence of approximately .02% to .03% (200 ppm to 300 ppm) concentration of CO2 in our atmosphere the surface mean temperature of the globe would be -18 °C. (Peixoto, J.P. and Oort, A.H., Physics of Climate Springer, 1992, p. 118.)

• If CO2 reached 1% the surface temperature would be > 100 deg C – our oceans would boil. (Explained by Arrhenius in 1896)

Changing Economic Behaviour

There are perhaps six ways that governments fix/intervene or influence economic behaviour

1. Government takes over the market entirely• e.g. Communism / Socialism. “We are from the government and

know what is good for you” e.g. China!

2. Government Participation in markets• E.g. Nationalisation or share holdings in major infrastructure industries

3. Criminal code • E.g. Insider trading laws, to prevent distortion of share markets.

4. Behaviour Change – Moral/Social/ Religious incentives. • E.g. “Be a good citizen”, Waterwise campaign, “Your litter is OUR

problem” etc.

5. Incentives – Government Grants• E.g. R&D grants, Renewable energy grants

6. Incentives and Disincentives Through Taxation• E.g. We tax income but not investment. R&D has larger tax

deductions.

The Carbon Trading seeks to address what economists call a “failed market” –i.e. A market where individuals or entities take profit by forcing others to bear the costs.

The Concept Behind Carbon Trading “The Failed Market”

Pegasus Gold Corp (1979 ~ 1998)

Example : Cyanide Leach Mining in Montana

Zortman /Ladusky Mine 1998

Total Gold : 2,529,644 ouncesProfits : US$ 300 million

Cleanup Bond : US$ 33 millionActual Cost : US$ 63 million

- US$ 30 million

• Pegasus declares bankruptcy 1997.

• Executives get US$10.4 million in success bonuses! (1995 to 1997)

Taxation of carbon emissions can occur in three ways

1. Direct Taxation of emissions

2. Baseline and Credit Trading• “Credits” for reducing emissions from a BAU

baseline• e.g. NSW Govt Greenhouse Gas Abatement

Scheme (GGAS - 2003)

3. Cap and Trade System• “Permits” to emit• Fixed cap on total emissions (= total number of

permits)• “e.g. The CPRS

SKM Sustainability Group

WHY NOT A “CARBON TAX” OR “BASELINE AND TRADE”?> With perfect information a direct tax can achieve the same outcome as

either of the trading systems & vice versa

> In practice outcomes from taxation & regulatory approaches may be different:o Cap & trade system

• Emissions outcome ‘certain’, but price is uncertain• Pressure on govt in setting cap – but market determines price• No carbon credit incentives for new technology

o Taxation• Price is “certain”, but emissions outcome is not• Pressure on government to alter tax / price.• Uncertainty about progress towards targets

o Baseline and Credit • price and emissions outcome are uncertain• Pressure on govt to determine BAU case for every industry• Uncertainty about progress towards targets.• Focus on efficiency but not emissions• Market determines price • Carbon credit incentives for new technology

THE PROBLEMS OF LEAKAGE & POLITICAL INFLUENCE

> Carbon Trading Schemes apply an economic theory that assumes that all business play to the same rules.

> When trading partners do not participate our Emissions Intensive Trade Exposed (EITE) industries “leak” to economies that do not have a tax on carbon.

> Heaviest Polluters EITE Industries and “Strongly Affected Industries” (i.e. Coal burning power stations) receive compensation to remain in Australia and/or stay in business.

o EITE Industries • Unclear compensation under CPRS but last indicated

to be 95% assistance for up to 45% of permit value for highest emitters.

o Heavily Affected Industries• Last indicated to be $7.5 billion in direct

compensation

• Impact of CPRS ~ 4.3% of revenue

• Nickel Laterites alone ~ 5.6%

• Nickel Sulphides alone ~ 1.6 %

Nickel Industry - Example

Source: Graph courtes of G. Fariss Mincorp Limited

• The Nickel Industry is not eligible for special treatment (“EITE or Strongly Affected Industries” ) from the CPRS

• While Prices remain low the industry is marginal and vulnerable to carbon price regardless of whether trading partners are being taxed or not.

• Nickel Laterite production is particularly vulnerable and some operations will shut down

• Some parts of the community will be adversely affected. (Redeployed in new industries? )

THE ENERGY ECONOMY IN 2050

• Non-electric energy is mostly heating , efficiency saving potential is 20% (at best)

• 100 % cuts in “other energy” and transport emissions can (ONLY?!!) be achieved using clean electricity

• Electrifying the whole energy sector with low GHG emitting equipment will achieve the 60% cut to Year 2000 emissions.

• In 2050 the Electric power infrastructure would be four times larger than the infrastructure we have now.

CO2 Emissions Engineering - Conclusions• Fossil fuels are 70% of all GHG Emissions.

• A 60% cut in Year 2000 levels of CO2 can be achieved by electrification using low GHG technology (renewable and/or nuclear )

• Electric power infrastructure would be 3 to 4 times larger than it is today at a cost of $400 ~ $525 billion over 40 years. (The CPRS predicts an electric sector only 1.5 times larger)

• Carbon Trading has underlying theory which assumes a free and fair market. Its underlying assumptions are violated leading to the largest polluters being compensated to continue “business as usual”

• Australia’s CPRS scheme currently relies heavily on demand-side management and will cost $3.3 trillion over 40 years in carbon taxes.

• “Tax and Grant” is a lower cost way of reducing emissions. It will decouple the economy from fossil fuels, and produce a much more robust electric sector (135 ~ 180 GW compared to c.a. 70 GW).

Page 40: Australias Co2 Reduction Targets By J Bremer

SKM Sustainability Group

“Carbon Trading” vs “Tax and Grant” Conclusions

• If the market was “free and fair” renewable energy could compete at $25 / tonne-CO2 with govt funding on $1 for every $2 spent basis.

• At $10 / tonne-CO2 , renewable energy could compete with coal with a 50:50 funding, provide the tax is in a “free and fair “ market.

International Carbon Trading – and Emissions Reduction

• Is the world in a Mexican stand off on CO2 mitigation?

• Who will make the first move? And why was the developing world reluctant to follow the Western’s world’s ETS model?

Copenhagen and The Future

* Quotation from Prof. Ross Garnaut, Garnaut Report 2008

o Australia and Western Nations went to Copenhagen with “Demand side” solutions.....Cutting consumption ONLY WORKS WHEN ALL INDIVIDUALS ARE ALREADY WEALTHY!!

o Carbon Trading and “Demand Side” solutions do not work in the developing world. (Consider 600~800 million Chinese and Indian people aspiring to a middle class lifestyle!)

o “Tax and Grant” is a “Supply Side” approach to emissions reduction. It seeks to INCREASE supply of energy to match future demand while lowering CO2.

o The “very large” cost of “Tax and Grant” is in the order of 1/8th to ¼ of the costs contemplated in the ETS.
