Professor Tasman Crowe:

I had not spotted that. I completely agree; that is certainly what it implies. There is now such a body of international evidence that suggests 30% is where we need to be. In fact, there is evidence that we should be going further. One of the big conclusions of the new UN Convention on Biological Diversity, CBD, global biodiversity framework is that everyone should be aiming for 30% by 2030. That was long debated and discussed and agreement was eventually reached. I agree that it should be a firmer phrasing. I had not really spotted those two little words "up to".
