Ecosia
Ecosia is a not-for-profit search engine founded in Berlin in 2009 by Christian Kroll. It earns money from search ads and dedicates its profits to climate action, especially tree-planting and restoration projects, while positioning itself as a privacy-friendly alternative to larger search engines.
What Ecosia is
Ecosia is a search engine and browser company built around a climate mission. People use Ecosia.org to search the web much like they use Google, Bing, or DuckDuckGo, but the company directs its profits toward environmental projects. That makes Ecosia as much a social-business case study as a search-engine case study.
How it makes money
Ecosia earns money mainly when users click ads shown with search results. Like other search engines, the value of an ad click depends on the query, country, advertiser demand, and other factors. Ecosia says its search ads are delivered through partnerships with Google AdSense and the Microsoft Advertising network.
Search partners and results
Ecosia is not a pure independent web crawler in the way Google or Bing are. Its results and ads draw on search partners, while Ecosia adds its own product layer, privacy choices, environmental indicators, and impact model. This means its quality and privacy tradeoffs depend partly on its partners and partly on Ecosia's own handling of users and data.
Trees and climate impact
Ecosia funds tree planting and restoration with local partners. The company emphasizes planting the right trees in the right places, long-term survival, biodiversity, and community benefits. Its tree counter is not a simple one-search-equals-one-tree measure; Ecosia says it counts trees expected to survive long term and typically plants several seedlings for each tree it expects to survive.
Transparency model
A major part of Ecosia's credibility comes from publishing monthly financial reports and project updates. These reports show income, costs, reserves, and money directed to climate action. Transparency does not remove every question about tree planting, but it gives users a way to inspect whether the business model matches the public promise.
Privacy and stewardship
Ecosia presents itself as privacy-friendly and says it cares about trees rather than user data. It also became steward-owned in 2018, meaning the company says it cannot be sold for private profit or have profits extracted by shareholders. This ownership structure is meant to lock the mission into the company rather than treat it as a marketing campaign.
Rise and differentiation
Ecosia rose by offering a clear reason to switch search engines: everyday searches could fund climate action. Its differentiation is not that it has the largest index or the most advanced ranking system. It is that it turns a routine digital habit into a visible environmental contribution, while trying to stay transparent about money and impact.
Why it matters
Ecosia matters because it expands what a search engine can be judged on. Search quality still matters, but so do business structure, environmental claims, privacy, transparency, and dependence on larger search partners. It asks whether users can redirect part of the economic value of search toward public-benefit goals without giving up too much convenience.
