The document is a detailed draft technical review of potential environmental impacts associated with the segment of the pipeline in the US, including: impacts from construction, impacts from potential spills, impacts related to climate change, and economic impacts. Aside from the potential construction and spill impacts of the pipeline, the scope of the climate change impacts have become the most contentious and politicized issue surrounding the pipeline.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. From a global climate change perspective, it does not matter where or from what source the reduction occurs: the effect on the atmospheric concentration of GHGs would be the same.
