Some thoughts:
Yes, if you define "environmental journal" as any journal that ever published an article dealing with environmental issues. Determining this will often involve original research and interpretation.
No, if you go by the inclusion criteria given in the lead of this list: this journal clearly is not "focused" on environmental issues, even though they may be included in the scope.
No, if you go by the journal's homepage, which not even mentions the word "environmental".
So it all depends on how you want to define "environmental journal". Personally, I would define that as a journal dedicated to environmental issues, not just any journal that occasionally also publishes something related. But I also know that David tends to go for the latter, wider definition -)
