www.ecosia.org plants tree for your search requests.
Sounds crazy, I admit it. I didn't know the site myself until a few days ago, but now I have looked into it intensively. I wouldn't introduce this project if I wasn't convinced of it myself. Above all I found it also exciting that it is a German company. If you are not interested in the underlying company and how it works, but want to join, scroll down to "How can you use Ecosia?". For everyone else, I'll explain the project briefly. The basic principle is this:

The obvious criticism now would be that although Ecosia spends money for planting trees, it takes most of the profit into its own pockets. However, Ecosia actually uses at least 80% of the financial surplus for forest cultivation.
This is why we use all of the income which is not needed to run the company to support reforestation efforts. Every month we use at least 80% of our surplus to finance tree planting projects.
Income- How is the project financed?
For all who don't know exactly how search engines generate revenue, here is a short explanation from me. You probably know this, no matter which search engine you use, you will see so-called "sponsored links" in your search results. Sometimes they are also marked directly as Ads. Here are two examples:
Search with Chrome + Ecosia Addon
Search with Edge via Bing
If a user clicks on one of these links, Escosia gets paid. So basically it's similar to an affiliate link like you may already know it from online stores like Amazon. To go into the financing in more detail, let me quote briefly from the corresponding Wikipedia article[1]:
Ecosia shows advertisements next to its search results, and are paid by their partners at Bing for every click on a sponsored link for having directed users to their advertisers. Considering that not every Ecosia user clicks on an ad every time they search, Ecosia states that on average a search raises around half a Euro cent (0.005 EUR).
Additionally I would like to mention that Ecosia does use an algorithm to filter out "fake" search queries. So you programmers can't work around it.
Transparency
For me personally, transparency is always one of the most important aspects of such projects. Just as with monetary donations, you want to know how the income is used. In this respect, we really must praise Ecosia very much. Each month, a financial report is published which can be viewed online. Here is for example a screenshot of the current report from June 2018[2]:
In the report you will find following statement:
This month we financed the planting of 4,850,375 trees.I think it's pretty good for just a month. It would be great, if you would just have a look yourself at the PDF if you are interested You can find it at the end of this post at the sources.
Data privacy
The advantage that springs to mind for me here is the fact that it is a German company. German or/and EU law applies. Another indirect advantage is that by (theoretically) abandoning the Google search engine, you make it (minimally) more difficult for Google to create a user profile of yourself. Ecosia does not promise to create user profiles and also states on its website that all search queries will be made anonymous after 7 days. The search engine also only allows connections via a secure HTTPS connection. They also mention directly, if you have activated a "Do Not Track" option in your browser, that they do not collect any analysis data at all. Many websites like to ignore this setting. In general, Ecosia is quite upfront here. After all, they have to collect certain data or pass them on to Bing. In this regard, however, they only store the least amount of data necessary. They also explain their procedure very transparently on their own website[3].Who is behind Ecosia?
