Tar sands get a lot of bad press, much of it to do with the fact that the extraction and processing of tar sands bitumen creates a lot more pollution than other fuel sources. A few companies are working on a technology that could change this, though. If all goes to plan, the greenhouse gas emissions from tar sands development could be significantly reduced, diminishing one element of environmental harm that has fanned opposition to this fuel source. Watch the video below to learn more about this technology and what its implications could be.
