Find the right pathway for your project

Quality certification establishes the foundation, while carbon removal certification verifies and tracks the resulting climate impact.

How the pathways work

Two pathways, different goals

Quality certification examines the biochar and the way it is produced. Carbon removal certification follows the carbon beyond production - quantifying its climate impact, verifying its storage and recording the resulting carbon sink.

Product quality

Certify the biochar

  1. 01 Assess the production

    Feedstock, technology, process controls and sustainability requirements are reviewed.

  2. 02 Test the material

    Biochar properties, contaminants and quality parameters are measured against defined thresholds.

  3. 03 Certify product quality

    The outcome confirms that the production process and biochar meet the applicable requirements.

Carbon removal potential

Certify the climate impact

  1. 01 Quantify the removal

    The net amount of atmospheric CO2 removed is calculated using the applicable methodology.

  2. 02 Track the carbon sink

    The material, its application and long-term storage are monitored with full traceability.

  3. 03 Verify and register

    The climate impact is independently verified and recorded as a unique carbon sink.

For biochar projects, the pathways often work together.

Quality certification establishes the foundation, while carbon removal certification verifies and tracks the resulting climate impact.

  1. Step 1 · Biochar certification Start with quality certification

    If you are a biochar producer, start with quality certification.

  2. Step 2 · Carbon removal certification Move on to carbon removal certification

    Once your quality certification is in place, you can move on to carbon removal certification to quantify and certify the carbon removal generated by your biochar.
