ORE: an asset at Treeseve

If you follow us on our social media, you must have seen us mention “ORE”, but do you know what those initials stand for? We explain everything to you!


What is an ERO?

The real environmental obligation (ORE) is a land device environmental protection attached to a piece of land (hence the name “real”, from the Latin RES the thing). They were created by the law of August 8, 2016 for the reconquest of biodiversity, nature and landscapes. This allows landowners to create sustainable obligations to protect the environment on their land.


Environmental protection obligations

The ERO is a contract concluded between the owner of a property and a public or private entity acting for the protection of the environment. It makes it possible to put in place obligations with a view to protecting biodiversity and ecological functions.

The ERO allows the owner to define the obligations he accepts. They can be both active obligations (to do) and passive obligations (not to do).

ORE contract

What shape should an ERO have?

An ERO must meet two formal requirements:

  • Be drawn up in the authentic form, that is to say that the contract “hasbeen received with the required solemnities, by a public official having competence and quality to instrument< /em>” (articles 1369 and following of the civil code). This public officer can be a notary or, in the case of an ORE concluded with a public authority, the mayor or the president of this authority.
  • Be registered with the land registration service. This procedure thus makes it possible to establish the validation of the contract.


Regarding its content, three elements must appear on the agreement:


The reciprocal commitments of the parties to the contract, i.e. those of the owner of the property on which the ERO will apply, and those of its co-contractor.


The duration of the obligations which will be freely set by the parties


Possibility of revision and termination


A long-term commitment

The duration of the obligations set by the ERO can be freely chosen by both parties. Thus, these bonds can have a long duration, up to a maximum of 99 years. Each party is bound to respect these obligations until the end of the ERO.

The obligations continue for the entire duration of the contract, even in the event of a change of owner. This is why BROs are much stronger legally than an obligation that would only be attached to one person


An innovation at Treeseve

As part of its plantations, Treeseve asks the owners of the land (companies or communities) to sign, before a public officer, an ORE.

By this act, the owners of our climate forests undertake to protect these forests, or groves, and in particular not to cut trees for a period of up to 99 years.

It is this duration that translates the principle of permanence, necessary to assure the companies that finance the plantation that it will be protected in the very long term.

Other mutual commitments, post-planting, will be set out in the Real Environmental Obligation agreement. In return, Treeseve undertakes to carry out the annual scientific monitoring necessary to provide partner companies with traceability of the plantations in terms of species survival and growth. These detailed measurement elements will be communicated to the owner of the land.

To date, we have signed OREs with 11 municipalities or communities including Caen, Caudry, Chauny, Urban Community of Dunkirk, Florange, Gasville-Oisème, Metz, Mondoubleau, Mulhouse, Saint- Denis-sur-Sarthon, and Laon. A final one is being signed to close the 2021/2022 season and half a dozen new ORE conventions is already being drafted.
