Accurately measure the proportion of biogenic carbon in your biofuels, solid recovered fuels (SRF), and CO₂ emissions using carbon-14 analysis.
CIRAM supports manufacturers in quantifying biogenic carbon tomeet regulatory requirements, ensure the accuracy of carbon footprints, and enhance the reliability of environmental disclosures.
Biogenic carbonrefers to carbon derived from recent biomass (plant, animal, or microbial matter), as opposed to fossil carbon derived from oil, gas, or coal.
Unlike fossil carbon, biogenic carbon is part of a short natural cycle: it is absorbed by living organisms and then released when those organisms are broken down or burned. In carbon footprint calculations, it is generally considered carbon-neutral, unlike fossil carbon.
When it comes to biofuels, RSDs, biogas, or CO₂ emissions, identifying the share of biogenic carbon makes it possible to:
Major players in the energy, waste management, and chemical industries turn to CIRAM to characterize their biofuels, CSR, and CO2 emissions.
European regulations require producers and users of alternative fuels—such as biofuels or Solid Recovered Fuels (SRF)—to demonstrate the proportion of renewable carbon in their inputs and emissions. This measure is essential for:
At CIRAM, we produce reliable analytical results that are accepted by certification bodies, regulatory authorities, and industry partners.

To quantify the proportion of biogenic carbon in biofuels, solid recovered fuels (SRF), or CO₂ emissions, CIRAM relies onaccelerator mass spectrometry (AMS) analysis of carbon-14, the international reference method.
This technique makes it possible to distinguish between fossil carbon (which contains no carbon-14) and biogenic carbon derived from recent biomass. It thus provides a reliable and accurate measurement of the renewable fraction, which is approximately 0.3%.
The analysis applies to both fuels and industrial emissions, making it possible, in particular, to determine the proportion of biogenic CO₂ in flue gases and to improve the accuracy of carbon budgets.
Our protocols are developed in accordance with current international standards:
In addition, stable isotope analysis can be performed to refine the interpretation, particularly in cases involving complex mixtures or disputes.
Each sample is prepared and analyzed in our laboratory according to rigorously validated procedures, guaranteeing traceability, reproducibility and robustness of results. You benefit from a clear, standardized report that can be used directly in your compliance, certification or environmental enhancement procedures.
Unlike bio-based content analyses, which assess a material’s composition, this approach aims to characterize carbon flows within an energy and industrial context.
Request a studyCIRAM 's analysis process is rigorous and transparent:
We work with you to identify the type of sample, the applicable standard, the regulatory context and your objectives (declaration, audit, benchmarking, etc.).
We provide you with precise instructions for collecting, packaging and shipping samples (liquids, solids, gases).
Each sample is handled according to strict procedures to guarantee accuracy of analysis, even for heterogeneous or complex materials.
Analysis is carried out according to the relevant standard, with the possibility of quality control or double analysis.
You receive a full report, with biobased data expressed in %.
When you choose CIRAM, you benefit from the support of an independent laboratory, specialized in carbon-14 analysis and recognized for the quality of its services on complex matrices. We regularly work with :
We deliver our results within 10 working days, accompanied by a technical interpretation and, if necessary, a discussion with your teams to integrate the data into your reports or internal tools.
Contact our teamsSolid RSCs, liquid biofuels (ethanol, HVO...), biogas, CO₂ from flue gases, or complex mixtures (textiles, plastics, biomass...).
