Launched in 2017 on the 800th anniversary of the 1217 Charter of the Forest, the modern charter is an initiative of the Woodland Trust and sets out ten principles including planning greener local landscapes.
Council leader Adam McVey said: "Edinburgh is the UK's greenest city, with more trees than people, more green space than anywhere in the country and more green flag parks than anywhere else for people to enjoy. Since we took office in June 2017 there are 7,000 more trees in Edinburgh as we’ve ramped up our tree planting programme.
"It's crucial that our trees are accessible and a constant feature in our urban and rural landscape to keep our city healthy, beautiful and rich in biodiversity. Our support for the Tree Charter's ten principles is a public demonstration of our commitment in this regard."
Depute leader Cammy Day added: "By signing the Charter, we are publicly pledging to keep nurturing, planting, celebrating, cherishing and increasing Edinburgh's trees."
The Tree Charter's principles are:
- Sustain landscapes rich in wildlife
- Plant for the future
- Celebrate the power of trees to inspire
- Recover health, hope and wellbeing with the power of trees
- Protect irreplaceable trees and woods
- Grow forests of opportunity and innovation
- Plan greener local landscapes
- Strengthen landscapes with trees
- Make trees accessible to all
- Combat threats to habitats.
