With this feature, you can use your accumulated Climate Points to plant trees. Here’s how it works:

As soon as you have collected 500 Climate Points, you receive a credit. When you redeem one of these credits, a tree is planted for you right here. Get started now and plant your first tree: https://climate-quest.de/personals/credits/

By the way: The credit system might seem unnecessarily complicated at first glance, but it is actually important—after all, you wouldn't want to redeem your actual Climate Points, as doing so could cause you to drop in your Family ranking or lose a level.
