How to choose projects for CO₂ offsetting
Choosing the right reforestation project is key to ensuring your CO₂ offset efforts are meaningful, transparent, and aligned with your goals.
This article explains how to make informed choices based on your climate objectives, budget, and reporting needs.
🌍 Understand how offsetting works on Tree-Nation
Tree-Nation offers a curated selection of nature-based projects that can offset CO₂ emissions through reforestation. Each project has:
- CO2 included in each tree
- Verified CO₂ sequestration estimates per tree
- A detailed methodology aligned with climate science
-
Full transparency through your Forest Impact page carbon issuance and retirement logs
🌐 How to choose your certification
Tree-Nation offers two certification approaches based on how carbon is measured and validated:
-
Foundation: Uses confirmed carbon (AGC) datasets to quantify carbon sequestration with high precision, calculating CO₂ by the tonne as the project develops.
-
Mission: Uses EVI (Enhanced Vegetation Index) as an independent proxy to track vegetation growth and estimate carbon impact in a more flexible and scalable way.
Both approaches are fully transparent and based on remote sensing, but differ in the level of precision and methodology used to model carbon.
In addition, Tree-Nation integrates external and national certification frameworks (e.g. MITECO) where relevant.
For a detailed comparison of both approaches, see our dedicated certification guide.
✅ Are these certifications compatible with EU regulations?
Yes — EU frameworks such as CSRD focus on transparent reporting and methodology, rather than prescribing a single type of carbon credit. Tree-Nation provides the data and documentation needed to support these requirements.
However, Tree-Nation operates within the voluntary carbon space. Our certifications are designed for climate contribution and reporting, rather than formal regulatory compliance schemes.
