Carbon Standards Proposes Real-Time Monitoring for Industrial Biochar Kilns

Carbon Standards has opened a 30-day public consultation on a draft standard that would replace annual sampling at industrial biochar plants with continuous digital monitoring and batch-level verification. The final text is scheduled to take effect worldwide on December 30.

The Swiss-based registry published version 0.9 of its Technically Advanced Kilns (TAK) Standard on October 20. The Ithaka Institute developed the framework, which targets professional, closed-flame pyrolysis systems operating at industrial scale. Comments close on November 20, 2026.

Existing biochar standards typically rest on annual sampling and audit visits. The proposed framework changes that baseline.

What would continuous monitoring cover?

Under the draft, key production data would be recorded continuously and transmitted online:

• reactor and flue-gas temperatures
• oxygen levels
• biochar output

Carbon content would shift from periodic sampling to daily measurement. The system would cross-check production figures against feedstock consumption, temperature readings and carbon content.

Batches would qualify for certification only for periods supported by complete records. Volumes produced during gaps in monitoring would be excluded. In plain terms: no data, no certificate.

What are the operating requirements?

The standard sets conditions beyond monitoring. It requires pyrolysis to operate without fossil-fuel energy, mandates oxidation of pyrolysis gases, and sets continuously monitored limits for carbon monoxide and methane emissions.

The framework also draws a boundary between two functions. TAK certifies biochar production and quality; the carbon removal associated with the material is quantified and registered separately under the Global Biochar C-Sink Standard. The new framework links each registered carbon sink to a verified production batch, creating a documented chain of evidence.

Who is behind it, and what have they said?

Carbon Standards Chief Executive Ueli Steiner said real-time monitoring was designed to address uncertainty in carbon markets and strengthen confidence in the underlying data.

Hans-Peter Schmidt of the Ithaka Institute, the standard's lead author, framed the framework as a step beyond existing rules. "The TAK Standard goes one step further [than other frameworks]: it does not only set the rules, it verifies that they are met – in real time, batch by batch," Schmidt said.

The distinction matters for buyers of removal credits. A standard that verifies compliance continuously, rather than once a year, narrows the window in which unverified material can enter the chain. Whether the market rewards that rigor remains to be seen.

What happens next?

A webinar presenting the standard and inviting feedback is scheduled for November 11 at 11 a.m. CET. Carbon Standards said it would publish consultation feedback and structured responses before issuing the final version.

The decisive dates are firm: comments close on November 20, and the standard takes effect globally on December 30. Operators of industrial pyrolysis kilns now have roughly one month to shape the rules they will certify under.
