The State Department could release its final environmental analysis on the controversial Keystone XL pipeline as early as Friday, according to multiple media reports.

The report will include the findings of a years-long study into the environmental impact of the $5.4 billion construction project, which would carry oil from Canadian refineries to the Gulf Coast.

Sources who have been briefed on the draft of the document told Bloomberg News that environmental groups who opposed construction of the pipeline would likely be disappointed with the results. While the report will include some modest changes that respond to concerns raised by environmentalists, it is still expected to find that the pipeline would have only a minimal impact on carbon emissions.
