One of the big issues around CO2 capture and storage, about which there is a lot of discussion, is long-term storage as one of the factors in liability. But the other thing is the monitoring and measurement and verification that you're referring to. In a lot of the international discussions around this area, there's almost violent agreement between both the petroleum producers and the NGO community about the need for monitoring, measurement, and verification. The only difference between those two groups is how much monitoring and measurement is appropriate over the long term.
So it's widely recognized that for any regulatory regime for safe storage and appropriate site selection for CO2 storage, you have to have effective monitoring, measurement, and verification measures in place. I think that's what Environment Canada is saying, that if we're going to proceed with this technology, we have to have appropriate monitoring technologies in place, but also the appropriate mitigation measures if there is such leakage. That's the big factor here.
With respect to the London Protocol, there's been an agreement now that storage in geological media in the sub-sea can be permitted. Right now, there's a series of meetings in the scientific community to develop guidelines for any company or any organization that wishes to store CO2 in the geological media under the seabed.
