Not a bad idea if implemented intelligently. BUT...what does this have to do with Free Trade?

The old United States is a slave to NAFTA, The UN, black leaders. Every politician running for POTUS agrees with our servitude to these criminals.

Not sure how fixing buildings only in North America fixes any global issue.

My guess is that, if country A applies some more-restrictive regulations on building materials or design than country B, that would adversely affect building materials or design exported from country B.

While that by itself may not be a bad thing, if it becomes a method to give an artificial competitive advantage to country A's producers or designers, then it has strayed into NAFTA terrority. The idea, in theory, is to have a common set of regulations so the issue can be sidestepped altogether.
