Investors Demand Climate Risk Disclosure

Investors are becoming increasingly concerned about potential regulatory risks and economic dangers in a carbon-constrained world

A group of 65 leading US investors with collective assets totaling $7 trillion has teamed up with the European investment management firm, F&C Investment to put a halt to Wall Street financial regulators softening of the rules on tar sands reserves disclosed by oil and gas companies.

The Investor Network on Climate Risk and F&C Investment are concerned that the escalating risks posed by climate change have broad implications for oil and gas companies which could impact their future earnings, and that these risks fall into the category of known trends requiring company disclosure.

At a time when governments around the world are taking an increasingly hard line on carbon pollution, these investor groups feel it is essential that investors be able to assess accurately the risk profile of reported reserves.

As quoted in the UK Guardian, Elizabeth McGeveran, senior vice-president of F&C's governance and sustainable investment team said"Understanding climate risk will assist investors in understanding and evaluating reserves. Regulations already require the disclosure of known trends that companies can reasonably expect will have a material impact on net sales, revenues or income from continuing operations, and we believe that the disclosure of any estimated additional risks posed by the extraction and development of additional reserves will be important."

The SEC had been reviewing the regulations on the way reserves are calculated since 2004, when Shell fell foul of SEC rules and was forced to reallocate a quarter of the assets on its books. The move led to steep fines, the ouster of its chairman and a plunging share price.

Three months ago the SEC changed the rules to allow previously excluded resources such as tar sands to be classified as oil and gas reserves that, as with oil or gas, could be listed as probable, possible and proven reserves.

Previously, tar sands were defined as mining materials, and literally speaking they actually contain no oil in their natural state. Only by heating up the rock to boiling point, can any liquid be extracted. However, such large quantities of heat are required to obtain a usable fuel from the rock means that this is a far less efficient source of energy than conventional oil.

"The energy consumption required to extract a barrel from Canadian tar sands is very different to a barrel of crude from the Gulf of Mexico."said McGeveran. As oil prices rise, companies that use a lot of oil in ratio to the product they sell are obviously far more impacted by price rises. Tar sands mining has an input of 1 unit of fossil energy in for every 3.5 units of energy (their product) out. The lower this ratio, the more the cost of producing oil from shale will rise as fossil energy prices go up.

But mostly, this unusually high carbon method of extraction means that the climate impact of tar sands mining is much worse than that of regular oil and gas. So the move reflects changing attitudes among a very large group of mainstream investors about the impact of commercial activities that could worsen global warming. This group of institutional investors, among them the California Public Employees' Retirement System, Ceres and Parnassus Investments have signed a letter of concern about the tar sands proposals and called for the new carbon implications to be taken into account.

Ceres president Mindy Lubber says that there is a need for financial institutions to evaluate these kind of projects with carbon prices that reflect their true long-term costs once carbon-reducing regulations take hold around the world.

"Much of the problem is our reliance on outdated accounting systems. Our economy uses accounting systems that are precise in measuring capital goods and profits, but weak in measuring natural and human resource impacts. This narrowly-defined accounting system means that companies are often able to "externalize" natural resource costs. In other words, they can emit global warming pollution for free without paying for environmental damage. Society and taxpayers shoulders these costs instead."

We're now seeing the capital markets begin to incorporate the external costs of global warming, especially in Europe where government-supported trading systems and pricing mechanisms for every ton of carbon dioxide emitted have fostered a $30 billion a year carbon emissions trading program. "

Therefore, filers of reserves should be required to provide investors with information about the carbon content of proven, probable and potential oil reserves in their portfolio as well as the potential liabilities posed by their continued extraction and use.

The Other Sub-Prime Investment - Tar Sands

With 3 times the CO2 of gasoline how can tar sands pan out in the carbon constrained world of tomorrow?

Products derived from tar sands, which have three times the carbon emissions of traditional gasoline, are a risky investment, because new low carbon fuel standards will increasingly close off sections of the American market.

Requirements that alternative fuels must be at least 20% lower in carbon emissions than oil have already been implemented in California, where Democrats predominate in the legislature.

Clean fuel standards are supported by Obama and Senate Democrats who could gain a fillibuster-proof 60 vote majority in November. Given the Democrats' votes to implement the 20% low carbon fuels rule, a majority in 2009 would likely put an end to tar sands oil.

McCain stopped this bill from becoming law by his "veto" of the 2007 energy bill cloture-vote in December, killing the clean fuels requirement and many other clean energy requirements, but it will come up for a vote again, and in the meantime, voters are becoming more aware of the dangers of scraping the bottom of this barrel while climate catastrophe looms.

The Guardian quotes Mark Hoskin, senior partner at investment advisors Holden & Partners as saying, “There is a good chance that tar sands could be to the oil industry what sub-prime lending was to the banking sector.

The recent banking crisis has shown how the financial markets can totally misjudge both the risks and values inherent in company balance sheets. Oil companies depend on oil reserves for their market values. "

DesmogBlog lists the sub prime aspects of this ghoulish bet against the environment:

Oil sands mining is licensed to use twice the amount of fresh water that the entire city of Calgary uses in a year.
At least 90% of the fresh water used in the oil sands ends up in ends up in tailing ponds so toxic that propane cannons are used to keep ducks from landing.
Processing the oil sands uses enough natural gas in a day to heat 3 million homes.
The toxic tailing ponds are considered one of the largest human-made structures in the world. The ponds span 50 square kilometers and can be seen from space.
Producing a barrel of oil from the oil sands produces three times more greenhouse gas emissions than a barrel of conventional oil.

So, why would you invest in a fuel that is likely not going to even be legal within a decade? I guess you would be counting on a McCain/Palin victory.

Queensland Follows In Rudd's Carbon Footsteps

Anna Bligh has placed a 20 year moratorium on oil shale development until it can be proved environmentally sound.

The day he took office as Prime Minister of Australia, Rudd reversed Howard's fossil-fuelish ways by moving promptly to sign on to Kyoto. He had the support of most Australians: 84% say Climate Change is a real problem.

Looks like Queensland's Premier, Anna Bligh, is following in Rudd's carbon footsteps.

She is halting plans to dig up about 400,000 tons of rock for resource testing. She said first the Government would spent the next two years researching whether shale oil deposits "can be used in an environmentally acceptable way" before releasing her moratorium.

Premier Bligh said the company would be allowed to try to develop new technology, "And if that is proved satisfactorily, then the Government will have a look to see if other sites are suitable to be developed." This marks the second energy source Queensland has halted. The state already placed a prohibition on the mining and export of uranium until it can prove itself environmentally safe.

QER said it had looked into 60 different technologies for extracting shale oil and was confident that the one it had chosen would satisfy the requirements of Queensland's Environmental Protection Agency. The technique they plan to use is the Paraho process which involves drilling holes and inserting heaters in target underground zones to slowly heat the shale. Per Energy Bulletin

Once the shale is sufficiently heated, a chemical reaction starts and releases the lighter hydrocarbons, which rise. The heavier hydrocarbons remain within the formation. The lighter hydrocarbons, almost a gasoline-type product, are subsequently pumped out of the ground through conventional means.

The advantage of this new process is that it eliminates the problem of waste disposal, because the heavy hydrocarbons are left in their original form in the underground shale. Also, the process requires much less water.

In contrast, the old retort method requires a lot of water to cool the heated rock. Also, once the oil is extracted from shale, the greasy residue - which almost doubles in volume because of heat expansion - has to be disposed of.

Current oil shale mining makes at least 3 X more carbon emissions than traditional oil drilling and uses 3 barrels of water to make 1 barrel of oil, and already Australia is ten years into the worst drought in the developed world.

So if this technique does prove to be a more environmentally sound way to scrape oil from rocks, than what we are doing now, it will be big news.
