Unconventional oil increases climate change
Research done by independent energy consultants IHS CERA finds that unconventional oil from Canada’s tar sands would emit 5% to 15% more carbon dioxide ‘from well to wheel’ than regular crude (Oil Sands, Greenhouse Gases, and US Oil Supply, 2010). That’s an increase, but by far not as much as the opposing side claims. Moreover, new technologies like carbon capture and storage can mitigate the extra emitted carbon dioxide, making this a feasible alternative.
