There are legitimate environmental concerns that should be raised.  If for example a company produces goods for trade, and that production involves dumping waste into a nearby river (which companies in the other 2 countries would be prohibited from doing), then that pollution probably should be covered off somehow under NAFTA.  

But good luck trying to bring global warming into it.  Different standards under both governments, not to mention provinces and states.  Plus there's the inconvenient fact that Canada itself is not on track to meet its "international obligations" under the Paris Accord.  

Global warming is a global issue.  It requires a global solution.  A regional trade agreement is not the appropriate place for that.

Also, as a separate (and likely) rhetorical question, do you think the Liberals will raise these same issues in their negotiations on the Canada-China free trade agreement?
