I don’t have much to go on, all I can remember is one specific scene (which in my mind is towards the end of the book but maybe not) where this family (mum, dad, sister and brother) have travelled to the Artic(?) and have joined the queue to get on the spaceship to leave Earth - they got selected months/years before due to the parents having jobs that would be beneficial for a new colony (scientist etc) as I think the Earth was dying. There were protest groups near this queue about the selection process and not saving everyone and in this queue they meet an older woman who has also been selected who has just finished a travelling tour and tells them she has now visited all seven continents before leaving Earth and that her grown son has not been selected (because he’s an artist?). I seem to think it was from the daughters POV, or at least part of it was, it could have been dual timeline or multiple POV, and I seem to remember her narrating how once the family had been selected boys at school kept trying to date her in hopes that if she got pregnant they would be saved too? And that she and her brother had been kept busy with their mother scanning in family photos/documents which they couldn’t take physically due to a weight limit on the spaceship but they could take a digit copy (all had some sort of wristwatch with data) and that the family had to watch their own weight to make sure they could go and had a treat before they left (dads was possibly a pint of Guinness?)
This may not even be the main plot point of the book but it’s the part I can remember - there may have been another timeline in the story.
I read it around the early 2010 - it’s not Across the Universe by Beth Revis or These Broken Stars, but it’s around that era I believe.
Parts of this sound familiar - like the family going because of their jobs, the protests groups at the departure sight but not all. This is the one I read, maybe it's similar? The Mayflower Project It's the Mayflower Project by K.A. Applegate.

Any help greatly appreciated.
