Ecosia (derived from "eco" and "utopia") is a not-for-profit business[2] based in Berlin, Germany. It runs its namesake internet search engine, which launched on 7 December 2009 to coincide with UN climate talks in Copenhagen.[3] More recently the organisation has launched additional products such as a namesake web browser.
Services
Ecosia
Ecosia delivers a combination of search results from Yahoo!, Google,[4] Bing and Wikipedia.[5] As of 2023, it sources its search results predominantly from Google.[6] In 2024, Ecosia started building an independent European search index as a joint venture with Qwant,[7] and in August 2025 user queries started being partially fulfilled by the new index.[8]
Advertisements are delivered by Yahoo! and Microsoft Advertising as part of a revenue sharing agreement with the company.[9]
Ecosia Chat
Ecosia Chat is an AI chatbot powered by OpenAI's API which features a unique "green answers" option.[10]
Ecosia Browser
The Ecosia Browser is a proprietary web browser based on Chromium. The browser has a built-in ad blocker, AI chatbot, and a climate pledge rating that assess a company's pledges on environmental sustainability. Ecosia has also committed to producing 25Wh of renewable energy for each day that a user browses with the browser.[11][12][13]
Former services
Freetree, launched in 2022, was a browser extension that used commission from online shopping to plant trees.[14] Ecosia announced in June 2025 that it was shutting Freetree because it "never reached enough users to scale sustainably".[15]
Privacy
Ecosia states in its privacy policy that it does not create personal profiles based on search history or use external tracking tools. The IP address and search queries of the user are given to either Microsoft Bing or Google to "provide search results and ads" and to "prevent bot attacks and frauds". Additionally, Ecosia shares the user's IP address with Tripadvisor and Wikimedia when images from those services are displayed.[16]
For the Ecosia Chat feature, Ecosia retains queries to improve its service but does not store personal information.[16][17] They do not share personal data with OpenAI; however, any information shared during chats is sent to OpenAI.[18] Although the data from these chats will not be used to train OpenAI's models, chat data is stored in OpenAI's database for up to 30 days to allow access for issue resolution and conversation recovery.
Business model
The company uses renewable energy to power its servers and invests its profits in tree-planting projects, aiming to absorb more CO2 than it emits.[21]
In October 2018, founder Christian Kroll announced he had given some of his shares to the Purpose Foundation.[22] As a result, Kroll and Ecosia co-owner Tim Schumacher gave up their right to sell Ecosia or take any profits out of the company.[23][24]
Ecosia is also transparent about their financial status as their financial reports are readily available online on their website.[25]
In 2022, Ecosia stated that it earns "a few cents" on every click of an ad, as well as a portion of the price of a purchase made through an affiliate link
Partnerships
Microsoft
Ecosia has a long-standing relationship with Microsoft to keep its investment in infrastructure small, through the use of Bing's existing implementation and an ad revenue sharing agreement.[27]
TreeCard
In October 2020, Ecosia announced it had bought a 20% stake in the debit card company TreeCard.[28][29] Cards produced by TreeCard are made of British cherry wood instead of the customary plastics found in most other debit cards.[29]
Impact
On internet search
Ecosia in 2021 claimed that each search removes 1 kg of CO2 from the atmosphere.[36]
In January 2023, Ecosia handled 0.29% of European search requests, behind DuckDuckGo's 0.53%, Bing's 3.65%, and Google's 92.23%.[37]
As of 2024, Ecosia has handled 0.30% of European search requests and 0.09% of global search requests.[38]
On ESG
Over time, Ecosia has supported various tree-planting initiatives.
Ecosia uses 80% of its profits (47.1% of its
Availability
Ecosia can be used on any web browser from ecosia.org. Web browsers can also be configured to use the search engine from a built-in user interface without having to load a web page first.
Ecosia can be made the default built-in search engine on Google Chrome,[50] Firefox,[51] Safari,[52] Microsoft Edge,[53] and other browsers as by downloading the extension from the Chrome Web Store or Mozilla's Add-on site, among others. In Mobile phones, Ecosia has its own Chromium-based web browser app in Google Play Store and App Store.
As of 26 January 2016, with its version 26 release, the Pale Moon web browser has included Ecosia as a built-in search engine option[54]
Issues
Dependence on Bing
An article in Ethical Consumer examined Ecosia and its relation to its search provider, Bing.
Giving Ecosia an "Ethiscore" of 11, in contrast to Google (5.5) and Microsoft Bing (6.5), Ethical Consumer found Ecosia to be superior to the other search engine companies it looked at, but marked it down in seven categories for its relationship with Microsoft (the lowest scorer in those categories).[66]
Ethical Consumer made a point of clarifying that it's not the actual searches which lead to tree planting, but the click-through of search engine users to the ads, and called for improved transparency concerning its relationship with Microsoft Bing.[66]
Boycott of Google
On 12 August 2019, Ecosia announced it would not participate in the "search-choice" auction to appear on Android devices led by Google.[67]
