I'll try to address those issues. My colleague may want to supplement the answer.
I think inter-jurisdictional comparisons are always useful to determine how a jurisdiction is doing and whether or not there are lessons to be learned. Specifically your question is, can we compare performance as reflected under the NPRI with performance as reported under statutes administered by certain U.S. states? There I would suggest that what would be appropriate to do, as in any comparison, is to ensure that you're comparing apples to apples and oranges to oranges. The particular comparison that was provided to the committee—and we'd be happy to follow up with an objective assessment of the numbers—compared the full set of releases that are reported under the NPRI, which includes emissions to the atmosphere, direct emissions to water, and off-site releases, which are basically taking something and putting it in a waste disposal facility, which counts as a release in the NPRI. That's different from a reported emission to the environment under, for example, the New Jersey toxics reduction initiative.
While I think the main point of comparison in the presentation was to New Jersey—indeed, we have long tried to benchmark ourselves against New Jersey, which has an extremely effective toxics initiative—I would suggest that the data that you were presented with didn't compare apples to apples and therefore provided a rather large number on the Canadian side compared to a lower number on the U.S. side.
Again, what we'd be happy to do is give the committee the data, and not in a kind of defensive manner or explanatory manner, but just breaking down the data so that you can see emissions to air and emissions to landfill sites compared to....
