Thank you for your question.
I think if we had a price on carbon of $40 a tonne by next year, 2011, and that were to increase, in a phased way, to $100 per tonne by 2020, our own economic modelling shows the government could reach its greenhouse gas reduction targets. And in fact if we put a higher price on carbon, and again graduate that up, we can actually meet a reduction level that would have us in line with what science tells us we need to do to reduce emissions in order to avoid dangerous climate change.
So, yes, as colleagues have said, start with 40 bucks a tonne on the low end and you're going to see it jump-start to different CCS projects.
