Ecosia is a certified B Corp search engine based in Berlin that uses advertising revenue from web searches to fund tree planting and climate action projects around the world. Founded in 2009 by Christian Kroll, Ecosia set out to prove that everyday digital habits could finance environmental restoration at scale, turning something people already do billions of times per day into a force for reforestation, biodiversity, and renewable energy investment.
Unlike conventional search engines that maximize shareholder returns, Ecosia publishes monthly financial reports showing exactly how search income is allocated, with a substantial share of profits directed to environmental partners across 35+ countries. The company has planted more than 200 million trees to date, operates its infrastructure on 100% renewable energy, and has built a user base of millions who choose Ecosia as their default search engine, demonstrating that transparency and mission alignment can compete with the largest platforms in tech.
Ecosia generates revenue from search advertising and allocates a substantial share of profits to tree planting and environmental projects. Users contribute passively by searching the web, creating a scalable model for funding reforestation without requiring donations.
