Planting Seeds of Change
From 20 Years of Tree Planting to Peace Circle®
Mika Vanhanen – Educator, Peacebuilder and Founder of Peace Circle®
I’m Mika Vanhanen – a Finnish educator, musician and peacebuilder with over 30 years of experience in sustainability education and global collaboration.
In 2000, I founded ENO – Environment Online, a school network that grew to include over 10,000 schools in 157 countries and inspired youth to plant more than 30 million trees.
Today, I continue this work through Peace Circle®, a concept I’ve developed over the years to support reflection, local peacebuilding, and value-based education – from grassroots to cities.
I have recently established a sole proprietorship to offer Peace Circle®-based talks, workshops and support – if and when opportunities arise. I’m also working on a doctoral dissertation, and exploring potential funding to deepen this work.
“Treat all living things
as you wish to be treated.”

Planting trees and building bridges
My journey began as a teacher in a small Finnish school in the early 1990s. I believed – and still believe – that education is not only about information, but about connection, action, and care.
We were among the first to join the GLOBE programme after the Rio Earth Summit, using early digital tools to observe nature and share findings with students around the world. That experience planted the first seeds of what would become ENO – Environment Online – a global school network for sustainable development.
When I launched ENO in 2000, the term “Education for Sustainable Development” had not yet been introduced by the UN. But in practice, we were already living it – combining digital collaboration, hands-on action and global solidarity.
Over the years, ENO grew into a movement of over 10,000 schools in 157 countries. Together, we’ve planted more than 30 million trees – and built bridges of trust across borders, generations and cultures.
Later, I worked with TreebuddyEarth, developing transparent, tech-enabled climate action with communities and companies. But I’ve always stayed rooted in the power of education.
In 2022, as war returned to Europe, I founded Plant and Care for Peace – a non-profit network connecting tree planting with peace education, as a quiet act of solidarity and hope.
In 2024, I launched Peace Circle® – a replicable model for values-based learning and community dialogue. It brings people together to plant, reflect and grow peace in shared spaces – starting in urban areas, where peace and nature are often missing from daily life.
And along the way, I’ve continued to run – and to write music – quiet threads that keep me connected to the rhythm of life and learning.
