Biochar carbon credits are increasingly included in net zero strategies as organisations look for durable, long-term carbon storage. When designed and deployed well, biochar-linked approaches can offer meaningful climate benefits alongside wider environmental outcomes.
For purchasers, understanding how biochar carbon credits create and retain value over time is essential.
Not all biochar-linked credits are the same. The differences are rarely visible in headline figures, but become clear when the underlying system is examined.
Carbon value is created through use
Biochar carbon credits do not deliver climate benefit simply through the production of biochar.
The climate value associated with biochar depends on what happens after production, including:
- How the biochar is used
- Where it is deployed
- Whether it remains in place over the long term
A credit linked to biochar that has a clear, realistic route to deployment is fundamentally different from one that relies on future assumptions.
Permanence is achieved through use, not intention.
Why deployment matters to purchasers
For carbon credit purchasers, deployment is not an operational detail — it is central to value.
Biochar achieves long-term carbon storage when it is:
- Incorporated into soil systems
- Encapsulated within materials
- Embedded in applications where removal is unlikely
Without a defined deployment pathway, carbon benefits remain theoretical.
This does not mean projects without immediate deployment lack intent.
It does mean purchasers should understand how and when permanence is achieved.
Understanding risk and durability
All carbon credit mechanisms involve assumptions. The key question for purchasers is how those assumptions are managed over time.
With biochar-linked credits, useful considerations include:
- What evidence exists for long-term residence in the chosen application?
- How is biochar tracked once deployed?
- What mechanisms are in place if deployment is delayed or changes?
These questions are not about fault-finding.
They are about understanding durability and risk.
The importance of systems thinking
Biochar works best when it is part of a clearly defined system that links:
- Feedstock
- Production
- Quality control
- Deployment
- Long-term residence
When these elements are aligned, carbon value is easier to defend and maintain. When they are treated separately, uncertainty increases.
For purchasers, clarity around the whole system provides confidence that carbon value is not just claimed, but sustained.
Asking the right questions
Purchasing biochar-linked carbon credits is not simply a transaction. It is a long-term commitment to an outcome.
Questions worth asking include:
- How does this biochar achieve permanence in practice?
- What assumptions underpin the carbon claims?
- How is long-term value monitored and maintained?
Clear answers to these questions help ensure that credits remain meaningful over time.
A balanced perspective
Biochar can play a valuable role in net zero strategies. Its strength lies in its potential for long-term carbon storage when deployed responsibly.
For purchasers, the most robust outcomes come from understanding how that potential is realised in practice — and ensuring that deployment, use, and permanence are treated as core components of value.
Getting this right benefits everyone involved.
It supports credible carbon outcomes and protects long-term confidence in the market.
