(More) Sustainable search engines can be easily set as the default search engine for search queries in the settings of your own browser via the address or search bar. This way you do not have to select the desired search engine every time.

Every search query on the internet requires electricity, which causes a carbon footprint. Although certified green electricity is purchased at the university and everyone can switch to a green electricity provider at home, the servers of the search engine operators also need electricity to process search queries. It is worth taking a closer look and choosing a search engine that is powered by renewable energy. Some search engines also finance charitable causes with their revenues from advertising. Here are two examples:

The search engine Ecosia claims to be climate-positive. Not only does it run entirely on renewable energy, but it also donates 100% of its profits to charitable projects that plant trees around the world, for example. With every search query, 1kg of CO2 is neutralised, according to Ecosia. Ecosia's search results are based on the Bing search engine. is a search engine that uses 100% of its search revenue to fund projects that contribute to the 17 SDGs. It too bases its search results on the Bing search engine and operates in a CO2-neutral way.

In addition, there are many other search engines that operate their servers with green electricity in Europe or Germany, or are committed to strict data protection. Simply search the web for the keyword "sustainable search engines" and select a search engine that meets your needs.
