The NF EN ISO 13833 standard: measuring the proportion of biogenic CO₂ in industrial emissions

At CIRAM, we perform radiocarbon analyses in accordance with the NF EN ISO 13833 standard to determine the proportion of biogenic CO₂ in industrial gas emissions.

Requirements and scope of the NF EN ISO 13833 standard

Published in March 2013, the NF EN ISO 13833 standard defines methods for measuring the proportion of carbon dioxide (CO₂) derived from biomass relative to fossil-fuel-derived CO₂ in emissions from stationary sources.

It was developed to provide a harmonized framework for characterizing industrial emissions in the energy, waste incineration, and thermal processes sectors, particularly in the context of carbon tracking and environmental reporting.

The standard is based on radiocarbon (carbon-14) dating, which makes it possible to distinguish between:

  • CO₂ from biomass (biogenic carbon),
  • CO₂ from fossil fuels.

This approach thus makes it possible to accurately determine the renewable portion of CO₂ emissions.

The NF EN ISO 13833 standard also defines:

  • Sampling protocols tailored to industrial gas streams,
  • Collection times vary depending on operating conditions (from a few hours to several weeks),
  • Requirements regarding the representativeness of samples,
  • Analytical methods based on carbon-14 dating.

Several analytical techniques can be used to measure carbon-14. Among these, accelerator mass spectrometry (AMS) is currently the gold standard due to its accuracy and sensitivity. This is the method used by CIRAM for the analysis of industrial gas emissions.

The standard is currently used in emissions monitoring systems, industrial carbon footprint assessments, and certain regulatory or environmental certification processes.

Applications of the NF EN ISO 13833 standard in industry

The NF EN ISO 13833 standard is used in many industrial settings for monitoring and characterizing CO₂ emissions. It applies in particular to:

  • At facilities that generate energy from biomass or waste,
  • In cement plants and heavy industry,
  • At incineration and thermal treatment facilities,
  • To regulatory emission monitoring systems,
  • Carbon reporting and environmental assessment processes.

In practice, emissions are sampled according to standardized protocols that ensure the representativeness of the gases being analyzed. The samples are then processed to isolate the CO₂ before measuring carbon-14 using AMS.

The analysis determines the proportion of biogenic CO₂ in total emissions. The results are typically expressed as a percentage of bio-based CO₂ or as the biogenic fraction relative to total CO₂.

This approach provides an independent measure of theoretical estimates or material balances, based directly on the isotopic signature of the carbon contained in the emissions.

Are you asking yourself these questions?

What types of emissions can be analyzed in accordance with NF EN ISO 13833?

The standard applies to gaseous emissions containing CO₂ from stationary sources, particularly in the energy, incineration, waste-to-energy, and heavy industry sectors.

Why measure the biogenic CO₂ fraction?

This measure makes it possible to distinguish emissions from biomass from those from fossil fuels, particularly in carbon footprint assessments and environmental monitoring systems.

How are samples collected?

Emissions may be sampled in gaseous form or collected on suitable media, in accordance with the protocols defined by the NF EN ISO 13833 standard, to ensure the representativeness of the measurements.

Is the NF EN ISO 13833 standard used in a regulatory context?

Yes. It is used in certain processes for emissions tracking, carbon reporting, and assessing the renewable energy share of industrial processes.
