CO₂ is CO₂. The molecule is the same regardless of where it comes from. But the carbon accounting is not. And increasingly, the buyers who purchase CO₂ for beverages, food processing, and industrial applications care about the distinction.
What Makes CO₂ Biogenic
Biogenic CO₂ comes from the natural carbon cycle. Plants absorb CO₂ from the atmosphere as they grow. When that plant material decomposes or is processed through anaerobic digestion, it releases CO₂ back into the atmosphere. Capturing that CO₂ before it is released does not add new carbon to the system. It is carbon that was recently in the atmosphere and will return to it regardless.
CO₂ from renewable natural gas upgraders is biogenic. The biogas comes from organic waste, dairy manure, food scraps, wastewater, or landfill decomposition. All of these feedstocks were recently living material that absorbed atmospheric CO₂.
Fossil Derived CO₂ Is Different
Most merchant CO₂ in the United States comes from fossil sources. Ammonia plants, hydrogen reformers, natural gas processing, and ethanol fermentation (which uses corn grown with fossil fuel inputs) are the primary producers. When this CO₂ is eventually released to atmosphere, either during use or after, it adds carbon that was previously locked underground back into the active carbon cycle.
This does not make fossil derived CO₂ bad. The CO₂ market exists because there are real industrial needs for the product. But from a sustainability perspective, the two sources are fundamentally different.
Why Buyers Care
Large beverage companies and food processors are setting scope 3 emissions targets. Scope 3 covers indirect emissions from their supply chain, including the CO₂ they purchase. Switching from fossil derived CO₂ to biogenic CO₂ is one of the most straightforward ways to reduce scope 3 emissions without changing any operational processes.
The product is identical. The purity is the same. The only difference is the carbon accounting. For companies that report sustainability metrics publicly, that difference has real value.
The Market Is Moving
We are not predicting a future trend. This is happening now. Multiple major beverage and food companies have told us directly that biogenic sourcing is a procurement priority. Some are willing to pay a premium for it. Others view it as a tiebreaker when evaluating suppliers.
At CleanCycleCarbon, every ton of CO₂ we produce is biogenic. It comes from RNG upgraders processing organic waste. That is not a marketing angle. It is a structural advantage that aligns with where the market is going.
