How Tree-Nation co-develops its reforestation projects

1. Methodology defines the framework

Projects are developed under a defined Tree-Nation certification methodology, which sets:

• The rules for project eligibility

• The approach to species selection and planting

• The calculation framework for carbon and ecosystem tracking

• The requirements for monitoring and verification

This ensures that projects follow a consistent and auditable structure.

2. Project Design Document (PDD) defines the implementation

For each planting site, a Project Design Document (PDD) is created.

The PDD functions as a project-specific implementation plan, and includes:

• Location and boundaries of the planting site

• Species to be planted

• Planting design and timeline

• Local environmental conditions and constraints

Unlike traditional PDDs, which often cover large aggregated project areas, Tree-Nation’s PDDs are defined per planting site, enabling higher precision, traceability, and alignment with on-the-ground reality.

Each PDD must comply with the selected methodology, ensuring that the project is both locally adapted and methodologically consistent.

3. Co-development with local partners

Projects are co-developed with local planting partners, who:

• Provide site-specific knowledge

• Adapt implementation to local environmental and social conditions

• Execute planting and on-site activities

Tree-Nation ensures alignment between the methodology (framework) and the PDD (execution plan).

In summary

Tree-Nation co-develops projects by combining:

• A standardized certification methodology (rules and calculations)

• With site-specific Project Design Documents (PDDs) (implementation at planting-site level)

This structure ensures that each project is consistent, transparent, and precisely linked to real planting activities on the ground.
