The Campaign to Stop GE Trees
Genetically engineered trees pose risks of contaminating forests, damaging ecosystems and harming communities
Action Alert! Sign on to stop the large-scale commercial release of Genetically Engineered Trees!

The President of Brazil, Luiz Inácio Lula da Silva, must immediately cancel the legalization of Suzano’s nine varieties of genetically modified eucalyptus trees.
The goal of the campaign:
To protect native forests and to defend the rights of forest dependent communities and Indigenous Peoples from the unknown and irreversible risks of releasing genetically engineered (GE) trees.
Why are trees being genetically engineered?
Genetic engineering makes changes directly to the genetic material of an organism, without mating, by introducing genetic material or material that induces change to that genetic material. This invasive process causes mutations and other impacts.
Trees such as eucalyptus, American chestnut, poplar and pine are being genetically engineered for traits including faster growth, insect and disease resistance, and altered wood composition. If released, these GE trees risk contaminating native forests, damaging ecosystems and harming communities.

Why should genetically engineered trees be prohibited?
Trees have a very long life-cycle. They can live for decades or centuries. This means the risks GE trees pose to forests and communities are impossible to assess over the lifespan of the tree. Because these risks are both profound and unknowable, GE trees must be prohibited.
Where can I find out more?
The campaign to STOP GE Trees has put together reports, newsletter, factsheets, and bulletins about genetically engineered trees. They can be found on the publications section of our website. Many are offered in multiple languages.
What can I do?
Are you looking to take action? Current calls to actions include sending a letter to stop GE Trees, signing on against industral tree plantations, and signing on in support of Indigenous and local communities devastated by the social and ecological impacts of industrial tree plantations, and threatened by the planned future use of GE tree plantations.
We also have a list of partner organizations if you wanted to get involved in your local community.
WHAT ARE GE TREES?
Trees are being genetically engineered for traits such as faster growth, and disease resistance.
