Standards for Reforestation within Restoration projects

As restoration is in itself an intricate network of interrelated actions, it makes sense that the best option to achieve long-term success is to use a holistic approach towards ecosystem restoration. With this in mind, Plant-for-the-Planet has developed restoration/reforestation guidelines covering biological, social, and economic aspects to ensure high quality projects are supported by our platform.  

These standards build on academic literature and the International Principles and Standards for the Practice of Ecological Restoration (by SER et al.), the Principles for Ecosystem Restoration to Guide the United Nations Decade 2021–2030 (by UN Environment Program, FAO et al.), and the Road to Restoration (by WRI & FAO).

We would love to receive any comments, feedback, or suggestion.

Please feel free to write to anytime.

Restoration Project Review Board

The Restoration Project Review board advises on restoration project standards and makes the final decision on which projects meet our restoration standards to participate on the Plant-for-the-Planet Platform.

    Code of Conduct

    All projects are required to comply with the Plant-for-the-Planet

    Other Risks
    Plant-for-the-Planet reserves the right to reject or later remove projects from the platform for reasons other than the ones stated in these standards. In particular if it believes that there is a considerable risk that the project is not sufficiently effective at restoring or protecting the ecosystem, or risks harm to the local ecosystem, the local community, the environment more broadly or Plant-for-the-Planet’s reputation. Projects may also be rejected, removed or frozen in the case of gross violation of non-mandatory standards.
    Enforcement Action & Reallocation Policy

    What is our Funding Reallocation Policy?

    The Plant-for-the-Planet Platform is committed to fulfilling our donor’s wishes. As far as possible, we want to ensure that donations go to the projects selected by our donors. However, when new information comes to our attention that indicate that a selected project is potentially unable to use the funds responsibly or achieve the promised ends or there is other doubt regarding their integrity, Plant-for-the-Planet reserves the right to reallocate the donations to other projects.

    For that purpose, we have developed a funding reallocation policy. This policy is a framework that outlines the circumstances and principles guiding the redirection of funds allocated to restoration projects. We want to ensure that resources are channeled efficiently to projects that create the greatest positive change.

    When Does a Reallocation Occur?

    A reallocation of funds may occur in specific situations to uphold our commitment to responsible funding and positive impact:

    1. For-Profit Organizations: Funds may be reallocated from projects led by for-profit organizations. This may be the case, when a project incorrectly reports their status or looses its non-profit status.
    2. Non-Compliance and Review: A project might loose donation privileges due to non-compliance with our standards during a review (off-site or on-site). The review board grants a window for improvement; if the project fails another review within the specified timeframe, funds are redirected. During the window, funds that have not yet been paid out to the project are frozen.
    3. Overfunded Projects: Projects receiving more donations than can be implemented effectively within 24 months might see funds reallocated to other initiatives to ensure resources are optimally utilized.
    4. Requests for Reallocation: An organization in charge of a project may request reallocation from one project to another, typically similar in nature.

    The decision to reallocate funds is made with careful consideration, engaging relevant stakeholders and maintaining open communication. Our priority is to ensure your contributions lead to meaningful, lasting change in restoration efforts.

    How Does the Reallocation Process Work?

    Our funding reallocation process is transparent and structured to ensure responsible allocation of resources. The steps include:

    1. Decision: The Project Review Board makes a decision to halt payouts and donation collection for a project. In urgent cases, the lead project reviewer might take the decision but is always subject to review by the review board.
    2. RO Manager Informed: The lead project reviewer notifies the RO Manager about the suspension.
    3. Disabling Donations: The RO Manager disables donations for the affected project.
    4. Project Communication: The project is informed about the suspension and given twelve months to pass a subsequent review.
    5. Review Outcome: If the second review is not passed within twelve months, or if not reapplied for, the reallocation process begins.
      • Project Selection: A similar project in price and ecosystem type, is chosen by the lead project reviewer.
      • Donor Notification: Donors contributing over €50 are informed about the new project reallocation. Donations are reallocated unless they object within a month. €5,000+ donors require active consent.
      • Database Updates: Donations are updated in the database, and history is reflected in backend and frontend systems.

    The process may be adapted depending on the specific circumstances.
