"Either it is or it isn't," implies that it's a binary. That's incorrect and muddies the waters. It's quantitative in a practical sense, as in geography or geology, not in an absolute sense as in mathematics. So "more carbon neutral" can be sensibly interpreted in this quantitative sense. Your use of language implying that it's a binary, "confuses the discussion to use it as such."

You probably think it's "unfunny" because you missed the logical distinction. Now that it has been explained to you how you were the one who derailed the discussion in the first place with bad logic, you probably still think it's "unfunny."
