Alipay has a function called ant forest, you use the app more often, you get more credit. And when it reach certain amount, aliaba will plant a small tree in the desert. People used to be crazy about this shit, but not for now. I guess the main reason is that these effort are good activities, but it didn’t help that much, compared to the effort from the government. At least on the this topic, they did a pretty good job, it last for decades, and it will countinue.
Alipay has another function called zhima credit score, which is related to the ant forest, you can rent bikes and power banks with no deposit when you have a high score. and it’s the base block of so called ‘social credit score’ for Chinese people
Projects around planting trees have often failed, in part from the choice of tree, in part because it takes more than just planting a tree to restore the habitat. It's generally better to work with the existing flora to promote growth and expansion, and/or help the stumps of trees that have been cut-down grow fresh again (e.g. https://www.youtube.com/watch?v=S5g60g9vmlY)
