Biochar, certified.

With Isometric, biochar project developers get paid sooner, and their buyers get certificates backed by proof, not trust.

Why biochar developers choose Isometric

Certified fast

Certify, Isometric's AI-powered certification platform, brings every step from feedstock to storage into one place and checks every data point, so certificates are issued in days, not months.

Durability options

Project developers can choose to credit biochar at 200 years, aligned with the EU's CRCF, or at 1,000 years with additional testing.

Accurately quantified

Every biochar certificate is backed by a protocol developed by the largest Science Team of any certifier and an independent network of more than 500 academics.

Globally accredited

Isometric is accredited by ICVCM, CORSIA, and ICROA, and its Biochar Protocol is approved to use the CCP label.

Isometric is accredited by ICVCM, CORSIA, and ICROA, and has nine protocols approved to use the Core Carbon Principles label.

How certification works

Every biochar project follows the same five steps, from checking your feedstock to certificates on the public Registry.

  1. 01
    Eligibility check

    Isometric confirms your feedstock, production approach, and storage meet the protocol. You can check your biomass first with the Feedstock Eligibility Checker.

    Before you start
  2. 02
    Public comment

    Your project's design is published so scientists, carbon market experts, and the public can comment on it.

    10 days by default
  3. 03
    Validation

    An independent verifier, chosen by Isometric, reviews the project design and visits the pyrolysis site.

    Once per project
  4. 04
    Verification

    Certify and an independent verifier review the evidence for each production batch, from feedstock to storage.

    In days
  5. 05
    Issuance

    Certificates for each batch are issued on the public Registry, with the data behind them.

In their words

“Isometric is well staffed, well organized, and laser-focused on scientific rigor, data transparency, and an ability to deliver results quickly.”
Josiah Hunt
CEO, Pacific Biochar
“Isometric helps us deliver on our monitoring responsibilities by making protocol requirements clear and data flows very efficient. Certify makes the verification process and our project development easier every day.”
Mart de Bruijn
Co-Founder and Director, Carboneers
“Certify is emerging as our single source of truth for certificate issuance. It's helping us accelerate the time to receive those certificates and deliver those to customers. It's now much more streamlined and the required inputs are clearer.”

FAQs

Is my biochar project eligible?

Your project is eligible if it makes biochar from eligible biomass, stores it for more than 200 years in soil, a low-oxygen burial site, a subsurface mine, or building materials, and delivers a net removal once every project emission is counted. It must also be additional and meet environmental and social safeguards. Check your feedstock or see the full criteria in the protocol.

How long does it take to get certified?

Validation can be completed in weeks. After that, Certify reviews each reporting period's data in hours, so certificates can be issued in days rather than months.

How does biochar certification work?

You validate your project once, then verify each reporting period, which usually covers a batch of biochar from sourcing through to storage. An independent verifier reviews your data in Certify, and certificates are issued once the biochar is in storage. See the five steps.

What does certification cost?

Under Isometric's buyer-pays model, certification fees are paid by the buyers of your certificates, not by you. That keeps Isometric aligned with the people who need certificates to be accurate. See how Isometric's fees work.

Will my certificates be 200-year or 1,000-year?

It depends on how your biochar is tested and where it is stored. Biochar in soil can be credited at 200 years using its H/Corg ratio and soil temperature, or at 1,000 years using random reflectance measurements. Biochar in low-oxygen burial sites or subsurface mines is credited at 1,000 years, and biochar in building materials at 200 years. Only the fraction of each batch expected to last that long earns certificates.

How many certificates will my project earn?

One for every tonne of carbon dioxide your project removes and durably stores, after subtracting every emission from sourcing the biomass, pyrolysis, transport, and storage.

What are pre-approved pyrolyzers?

Pyrolyzer models whose manufacturers have already completed Isometric's reactor validation. Select one in Certify and add those reactors to new or existing projects without validating the pyrolyzer again. See the pre-approved models.

Can I move a project from another registry?

Yes, as long as the project is registered only with Isometric from then on, so no removal is ever credited twice. During validation you share details of any registry you have used in the past five years, and your crediting period can start up to five years before you first submit. Talk to the team about moving.

How do Certify and Remi help with submissions?

Certify is where you build and submit your project. Its AI agents check every data point behind it, not just a sample, so the verifier can review it in hours. Remi, the AI assistant built into Certify, works alongside you in real time as you prepare your submission. See how Certify works.
