Our good news post comes from the Good News Network.

Reaching the milestone just before Earth Day, Ecosia, the nonprofit search engine, is celebrating 250 million trees planted worldwide, becoming the world’s largest planter of native trees.

Since its founding in 2009, Ecosia has built the world’s largest network of local reforestation operations, numbering more than 200,000 tree planters and 125 organizations worldwide. Users’ clicks and searches, as well as the ad revenue they generate, translate into funds the company uses to organize tree planting.

These partnerships have allowed the tech company to focus on working with local experts to plant 1,600 native tree species, including 144 endangered or vulnerable species, making it a leading contributor to threatened-tree conservation. These efforts are helping biodiversity hotspots recover and restoring ecosystems in communities for generations to come.

Founder Christian Kroll, together with Germany’s Federal Minister for the Environment, planted a tree to mark the 250 million milestone in front of the German federal parliament, the Reichstag, in Berlin, where Ecosia is headquartered.

“All of our successes have come from this powerful on-the-ground movement, ” said Christian Kroll, founder of Ecosia. “From one click in 2009 to 250 million trees today, our global community supercharged our climate action.”

GNN has previously reported on Ecosia. The search online often targets countries that are the most biodiverse, where tree loss directly corresponds with species loss. This has led them to launch projects in Nicaragua and Peru, Burkina Faso and Malawi, Indonesia, and Australia.

In 2018, for example, they created a tree nursery for 200,000 trees in Madagascar, to help create a forest corridor leading from an isolated habitat to the ocean. In 2019, they created a forest-agriculture project in Borneo to prevent locals from selling land to oil palm development.

That same year, Ecosia took measures to ensure it could never be sold and that no one, including the founder, could profit from or receive dividends from the company. This means that the business is set up purely to benefit the planet.

Growing trees and forests is a long-term game that goes beyond just planting seedlings. Some of Ecosia’s trees get planted because they guarantee future revenue for the community (e.g., fruit and nut trees or trees that boost harvest yields); these provide a strong incentive for the beneficiaries of these products to protect the trees long term. Other reforestation work provides returns on investment for financiers. These are the most well-funded.

However, not every tree has a straightforward financial return on investment, and therefore, making a case for long-term investment is not clear-cut. In fact, much of today’s deforestation is the result of trees not being valued much in economic terms.

This is why Ecosia’s work is so critical to reforestation. It can step in where return-seeking capital won’t. This allows vital ecosystems and communities to be supported without greenwashing or offsetting motives. A purpose company with only one shareholder: the planet.

Unique to any other tech company, Ecosia has a dedicated Tree Team: a group of forestry and nature conservation experts, social business experts, economists, and social scientists, focused on finding the right partners to work with, collaborating with communities, and planting the right species to ensure our trees thrive. It is the only company in the world with a CTPO (Chief Tree Planting Officer).

“We care about our trees long term, not just for some pretty pictures of young saplings,” shared Pieter van Midwoud, Ecosia’s CTPO. “We have developed a vigorous monitoring program to analyze whether projects that we started would benefit from further support. Ecosia, as a purpose company, is best placed to do this long term, and we hope to grow millions more trees.”

The next chapter for Ecosia is to make a bigger move into landscape restoration. Rather than solely assessing projects based on factors that affect the long-term benefits of trees—such as water supply, fuel access, and financial sustainability—the company has begun to take a more active role in influencing those factors.

“We know that collaborating together with the local community is the only way to run a successful restoration project long term, so combining tree planting with complementary interventions that enable farmers and nature to have a bigger impact will be further strengthened,” said van Midwoud.

The good news in this story is that a serious effort to enable sustainable tree planting is sponsored by a tech company. Today’s JohnKu talks about tech and the environment. I hope you have a great weekend.

Tech and conservation,

Are not usual bedfellows . . .

Good when it happens.
