Arctic oilThis is the scientific paper that should stop all Arctic drilling now. It should also stop the controversial Keystone XL pipeline.

It is yet another warning that business as usual for the oil industry is just not acceptable.

And it once again reiterates a simple truth so, so unpalatable to the Canadians: that exploiting the tar sands is incompatible with preventing climate change.

The paper should make deeply uncomfortable reading for any financial institution or oil company thinking of investing in the Arctic or the tar sands, or the heads of OPEC. In short, it affects everyone involved in the oil industry.

It should be essential reading for the CEOs of Gazprom and Shell, for one. And it should force them to change their unsustainable business strategies.

The paper, entitled, “Un-burnable oil: An examination of oil resource utilisation in a decarbonised energy system”, will be published by the journal Energy Policy in January. You can view a copy here. And then you should spread it far and wide.

The scientists warn of a large “disconnect” between developing new areas of exploration such as the Arctic and “pledges to restrict temperature rises to 2 °C. The continued licensing of new areas for oil exploration is only consistent with declared intentions to limit CO2 emissions and climate change if the majority of fields that are discovered remain undeveloped, which fatally undermines the economic rationale for their discovery in the first place.”

The scientists argue that “large volumes of oil currently considered to be reserves cannot be produced before 2035 if there is to be an evens chance of limiting the global average temperature rise to 2 °C.”

Globally, they argue, that nearly 600 billion barrels of oil reserves must remain unused by 2035, if widespread Carbon, Capture and Storage (CCS) is unavailable.

This is just under 50 per cent of current available reserves.

Even in a future scenario where there is widespread and rapid adoption of carbon capture and storage (CCS) in both the electricity and industry sectors, nearly 500 billion barrels must never be burnt.

In a scenario with no CCS, the scientists argue that no region can fully exploit their reserves although some regions must leave greater proportions of their reserves in situ than others: the Middle East must not use 55% or around 390 billion tonnes of its current reserves before 2035.

The warning over Arctic oil is clear: “These results suggest that the development of Arctic regions is largely inconsistent with an evens chance of limiting average global temperature change to 2 °C and that it may be reasonable to classify Arctic resources as ‘un-burnable’; this therefore calls into question the rationale for ongoing exploration efforts in Arctic regions, if stated commitments to emission reduction are to be taken seriously.”

Another way to look at this, if Shell or Gazprom are serious about pushing ahead Arctic drilling then they are not serious about addressing climate change.

If the Canadians are thinking that not drilling Arctic oil makes it more likely that the tar sands should be exploited, they should think again. “If the declared ‘proved’ reserves of these countries were to be believed, then 80% Canadian reserves and 92% Venezuelan reserves must remain in the ground,” argue the scientists.

It is worth repeating that figure: 80 per cent of tar sands reserves need to stay in the ground. And if that is the case, there is no need for the Keystone XL pipeline.
