9th Land Webinar

The Science & Practice of Ecosia's Journey to Grow 250 Million Trees

How did a search engine plant 250 million trees? Join us to discover how online searches translate into real-world impact, and how we’re not just planting and growing trees, but ensuring the long-term success and sustainability of our restoration projects.

To celebrate the 250 million trees milestone, Ecosia is hosting an online Restoration Seminar in collaboration with the journal Land.

This seminar will explore the science and real-world practices behind Ecosia’s global reforestation and restoration mission, featuring case studies from leading restoration experts across the world.

We will feature real-world on the ground example of how our partners are working to plant trees to create forest corridors and expand animal habitats, how finance and investment can integrate more trees into business models, how a brigade of firefighters is protecting millions of trees, how an invasive species is creating a business model for forest restoration and much more.

Headquartered in Berlin, Germany, Ecosia is the world’s largest not-for-profit search engine. It has planted 250 million trees across over 35 countries worldwide. In 2014, Ecosia was accredited as a B Corporation, and in 2017, it built the first of its four solar plants to ensure that it is 100% renewable. In 2018, Ecosia gave away its shares to the Purpose Foundation to ensure that they can never be sold and that no one, including the founder, can profit or receive dividends from the company. Ecosia was founded by Christian Kroll in 2009.
