Ecosia is a search engine that aggregates search results from multiple other search engines. The ad revenue from our searches funds the planting of trees worldwide. With over 200 million trees planted so far, Ecosia have learned to be fully transparent about their projects, and financials which are available right on that website. Set it as your default search engine, and start planting trees. They also recently released a Chromium based browser if that’s your thing - TechCrunch article for reference.
You should probably not call all reforestation as bullshit projects just based on a John Oliver video.
There is this interesting blog post on Ecosia :

I understand this is just a blog but there is good sources in there. Ecosia looks like a serious initiative and the fact that they got a B corp rating in Germany is impressive.
