We haven't done a detailed study to see what those would be. Our understanding and our belief is that it would be fairly heavy. It's not like applying a regular tariff, whereby you simply say it's going to be 10%, or whatever the number is, and you apply it. There has to be an assessment of the embedded emissions in imported goods, as well as preparatory work on what the emissions are in your own country, to have that comparability.
We are aware that the EU's process was a three-year-long process involving the staffing of a group. The U.S. International Trade Commission is just doing a study to do some of this preliminary work on what emissions are embedded in goods. That is a fairly heavy process too.
I won't say it wouldn't be a somewhat heavy process, but it would depend, as well, on how you design the system.
