In April 2021, I signed up to Ecologi to help compensate for my carbon footprint. Not only does Ecologi plant trees, but they also support carbon reducing projects around the world.
Ecologi has a really neat website actually and from as little as £1.25 a week, you can start growing your own forest and make a real difference in the fight against climate change.
(If you do sign up via my 'See my forest' link, we both get 30 trees. What's not to love about that!)
