MRV (Monitoring, Reporting, Verification): technology and partners

What MRV means at Tree-Nation

MRV ensures that:

• Projects are monitored over time

• Data is reported consistently

• Outcomes are verified using both field evidence and independent data sources

Rather than relying on a single method, Tree-Nation combines multiple layers of verification.

1. On-the-ground MRV (Tree-Nation controlled)

Tree-Nation directly monitors and verifies project activity through:

• Geolocated photos of planting and monitoring activities

• Planting and monitoring reports from project partners

• Site-level tracking through Purchase Orders (POs)

• Ongoing project updates over time

• Site visits and field checks 

This layer ensures that:

• Real planting activity is documented

• Projects are actively followed throughout their lifecycle

• Data is continuously updated, not just reviewed once

2. Remote sensing MRV (objective data layer)

Tree-Nation complements field data with satellite-based monitoring, which provides an objective and independent view of project performance.

This includes:

Vegetation monitoring

• Based on the Enhanced Vegetation Index (EVI)

• A scientific index developed by NASA

• Measures vegetation health and density using satellite data

EVI allows Tree-Nation to:

• Track vegetation development over time

• Detect changes in ecosystem health

• Monitor trends across large areas consistently

Aboveground Carbon (AGC) measurement

• Provided through partners such as Planet and Chloris

• Estimates the amount of carbon stored in vegetation using real-world data

This enables:

• Large-scale carbon monitoring

• Independent validation of biomass growth

• Comparison between expected and observed outcomes

Why this approach matters

Tree-Nation’s MRV system combines:

• Operational verification (what is planted and reported on the ground)

• Objective satellite data (what is actually happening at landscape level)

Satellite data represents the most independent layer of verification, as it cannot be altered or influenced by project stakeholders.

Together, these layers provide a more complete and reliable picture of project performance over time.

In summary

Tree-Nation’s MRV approach is built on two complementary pillars:

• On-the-ground verification → geolocated photos, reports, and project tracking

• Remote sensing verification → satellite data, EVI (NASA), and Aboveground Carbon measurements

This combination ensures that project impact is:

• Continuously monitored

• Independently assessed

• Directly linked to real-world outcomes
