From the age of 16, apparently, although kids aged 16 - 18 will need parental consent. Thoughts?

Interesting but not very comparable to the UK situation. Their original laws were much stricter than ours. Also not clear from the article what the implications are.

I think it will go ahead in many places. To understand the significance in each individual country requires an understanding of the overall legal system in each place. As we’ve seen in the U.K., the problem also relates to equality law.

Those in the U.K. have to concentrate on the U.K. situation and how proposed changes will affect women and girls. Only time will tell in other places.

Yes saw this yesterday. Self-ID is seen as the gold standard and very much the next step in the push for transgender recognition in many quarters, so I'm sure we'll see more similar decisions and deal with the 'its been fine in Ireland, Malta, Portugal....' line of argument.
As you have said, I'm not sure how this will affect sex-segregated spaces there and what exactly the rules will be - how easy is it to self-delare back again for example? What gets me is that the article points to the increase in even younger children saying they are trans gender, but the response appears to effectively be let's just make it easier to change, rather than examining what lies at the root of it.
