This video addresses both sides of the debate on whether the Keystone XL pipeline will increase GHG production. The proposed pipeline would ferry tarsands from Alberta to refineries on Texas's Gulf Coast. On June 25th, 2013, President Obama made it clear that he will not authorize the building of the Keystone XL pipeline if it results in an increase in greenhouse gases (GHGs). While it is widely understood that the tarsands are much more GHG intensive than traditional fossil fuels, the question is whether this would result in a net increase in GHG emissions. Those that support the building of the Keystone XL say that in the absence of the pipeline there would be increased transportation traffic (tankers and trucks) which would result in even greater levels of GHGs.
What this video does not address is the fact that more fossil fuel infrastructure and easier access to dirty sources of energy will detract from market based forces that would decrease our reliance on climate change causing sources of energy.
