On greenhouse gas emissions from Saskatchewan, I don't have absolute numbers, but I can tell you that per capita I believe they are the highest in Canada. That's not related necessarily to mining, but that's because our primary source of power in the province is from coal-fired generators. So from mining per se, I don't know, but for the mining byproduct it would be fairly high.
