On the life cycle greenhouse gas emissions for Kearl, IHS CERA, recently put out a study, I believe in November 2012, in which they compared an oil sands mine that uses a paraffinic froth treatment, which doesn't require an upgrader, to a basket of crude oil refined in the U.S. We could provide you with a reference for that study. It compares Kearl, or a Kearl equivalent, and its paraffinic froth treatment to any number of crudes and can give you a direct comparison on life cycle greenhouse gases.
With respect to the cost of reclamation, in terms of the funding of technology, industry, through COSIA, has collectively contributed about a billion dollars towards faster reclamation. I can't tell you exactly what various projects are spending on actual reclamation. I can tell you that Syncrude, in which we own a 25% interest, is spending hundreds of millions of dollars on reclamation.
