And one tree does 25kg per year. So each person should plant 14 * 365 / 25= 204 trees. Seems very reasonable.

Consider UK; 204 trees * 65 million people = 13.2 billion trees. Woodland estimates there's approx 3 billion trees in the UK now. That's over 4 fold increase in trees every year. I doubt the terrain/nature could support such a significant increase in just one year, let alone a number of years. But I like the idea of more trees.

The UK is one of the least forested countries in Europe. It is very doable.

It used to be covered in trees! Surely it can support forests again.

You don’t need a new tree each year cause they can live decades. UK 4xing it’s tree coverage sounds doable and nice!

:facepalm: you’re right! Just 4xing alone is enough to cover the population’s emission. I’m totally up for upping the tree population in the UK.

This planting should happen one time, not yearly. Of course every dead tree should be replaced though. If there are 204 trees capturing CO2 for every human (and these numbers are correct) we should effectively be carbon neutral. No idea if that is even remotely realistic though

UK population density is 715 / sq mi. World average excluding Antarctica is 154.

There are less densely populated places where more trees could be planted.

Yes but that is skewed by the South of England. There's a TON of hardly populated land in Scotland/Wales.
