Berman, author of This Crazy Time and co-founder of ForestEthics, pointed out that every independent study, including one from the U.S. Department of Energy, has found that the oil sands are one of the world's dirtiest forms of oil, producing three times more greenhouse gas emissions per barrel produced, and 22 per cent more than conventional oil when their full life cycle of emissions, including burning them in a vehicle, is included.

The nonpartisan Congressional Research Service found in a survey of published literature that because tar sands oil is more carbon intensive than conventional crude oil, the Keystone XL pipeline would increase U.S. greenhouse gas emissions by the equivalent of «approximately 558,000 to 4,061,000 passenger vehicles» annually:

On the contrary, Figure 1 is a conservative estimate of potential emissions from tar sands because: the economically extractable amount grows with technology development and oil price; the total tar sands resource is larger than the known resource, possibly much larger; extraction of tar sands oil uses conventional oil and gas, which will show up as additions to the purple bars in Figure 1; development of tar sands will destroy overlying forest and prairie ecology, emitting biospheric CO2 to the atmosphere.

Tar sands oil is one of the dirtiest fossil fuels in commercial production today and produces three to five times more climate changing emissions than conventional crude oil.

We have two main concerns: the risk of oil spills along the pipeline, which would traverse highly sensitive terrain, and the fact that the extraction of petroleum from the tar sands creates far more greenhouse emissions than conventional production does.

Additional escalation of the mining impact occurs as conventional oil mining is supplanted by tar sands development, with mining and land disturbance from the latter producing land use - related greenhouse gas emissions as much as 23 times greater than conventional oil production per unit area [152], but with substantial variability and uncertainty [152]--[153].
