|a Climate policy and analysis often focus on energy production
and consumption1,2, but seldom consider how energy transportation
infrastructure shapes energy systems3. US President
Obama has recently brought these issues to the fore, stating
that he would only approve the Keystone XL pipeline,
connecting Canadian oil sands with US refineries and ports,
if it does not significantly exacerbate the problem of carbon
pollution’4. Here, we apply a simple model to understand the
implications of the pipeline for greenhouse gas emissions as
a function of any resulting increase in oil sands production.
We find that for every barrel of increased production, global
oil consumption would increase 0.6 barrels owing to the
incremental decrease in global oil prices. As a result, and
depending on the extent to which the pipeline leads to greater
oil sands production, the net annual impact of Keystone
XL could range from virtually none to 110 million tons CO2
equivalent annually. This spread is four times wider than found
by the US State Department (1–27 million tons CO2e), who did
not account for global oil market effects5. The approach used
here, common in lifecycle analysis6, could also be applied to
other pending fossil fuel extraction and supply infrastructure. |
