Oops another nail: Keystone will create more pollution than previously calculated

Looks like the pipeline is in even deeper trouble as initial pollution calculations are proved wrong.

A proposed pipeline from Canada to the United States may result in much higher greenhouse gas emissions than previously calculated as it could fuel greater oil consumption through higher production and lower prices, a study said Sunday.

Researchers from the Stockholm Environment Institute used a mathematical model to estimate the Keystone XL pipeline’s potential for atmospheric pollution.

Unlike calculations by the US State Department, they took into account a possible consumption rise in line with production, the pair wrote in the journal Nature Climate Change.

It was not clear, though, what the production increase was likely to be.

Using basic supply-and-demand economic principles and assuming a rise in production, the team calculated the pipeline would yield greenhouse gas emissions of 100-110 million tonnes of carbon dioxide equivalent (MtCO2e) per year — “four times the upper State Department estimate” of 27.4 MtCO2e, they said.
