ECOSIA Search Engine

Ecosia Company Logo

What is Ecosia and does it work? 

A non-profit CO2-neutral search engine.

Ecosia is a social business and CO2 -neutral search engine that uses ad-generated revenue to fund planting trees. Each search with Ecosia removes roughly 1 kg of CO2 from the air. To achieve its objectives Ecosia cooperates with non-profit organizations (NGOs) across the world and uses 100% renewable energy thanks to having built their own solar plants so they can supply enough clean energy to power the searches.

How is it different from other search engines? 

Ecosia distinguishes itself from the main search engines in the market, trying to make a positive environmental contribution to society (Yunus, 2008). 

Ecosia importantly doesn’t use any third-party tracking tools, meaning that any search made on the service won’t be seen by any party other than Ecosia. Furthermore, any search made on Ecosia becomes anonymized after one week. In contrast, Google and Bing will hold onto bits of search data (such as the device or date), even after deleting browser history and cookies.

Clicks revenue to plant trees across the world

Clicking on ads generates revenue for Ecosia, which is paid by the advertiser. Ecosia then uses at least 80% of its monthly profits to plant trees where they are needed most. Here’s the math: an average search generates around 0.005 € of revenue. It costs roughly 0.25 € to plant a tree, which means that Ecosia can plant one tree every 50 searches. On average, these trees will each remove 50 kg of CO2 during an expected 15-year lifetime

Using ECOSIA at the Department of Chemical Engineering 

Our aim is to make Ecosia, the search engine that plants trees, the default across the department. 

Our sustainability objectives 

The UCL sustainability strategy is targeting carbon neutral activity across the university. By using Ecosia at the department level, we will have figures to showcase the number of trees we can plant when everybody in the department uses Ecosia as search engine. 

Tracking our tree count

By adding Ecosia to your browser, each of your connexions and search plants trees. We have one specific link created by Ecosia for UCL. Ecosia will share monthly reports so you'll be able to follow the Universities progress.

How can I set up Ecosia and plant trees? 

  • https://ecosia.co/UCL is the unique link for the university
  • Anyone that downloads Ecosia through this link will start to add to the UCL tree counter. If you already use Ecosia you first need to uninstall the extension from your browser and clear your internet cookies. You then need to re-install Ecosia using your university's link. Instructions can be found by visiting the ecosia website. (add link)


Is anywhere else in UCL doing this?

There was a student lead campaign back in January 2019 and Ecosia is still used elsewhere in UCL. On average, 22 trees are already planted each month as a result.
