Chemicals production — what makes this sector technically different.
Where carbon enters as feedstock rather than as fuel, an energy-based inventory misses the largest source in the plant.
Hardest data points
Where inventories in this sector fail.
- Feedstock carbon that leaves in the product rather than as CO₂, which a mass balance captures and an energy-based calculation does not
- Process emissions from reactions themselves, separate from the combustion that drives them
- Co-product and by-product allocation across a plant producing several saleable streams from one reaction train
- N₂O and CH₄ from specific processes, which carry high global warming potentials and are often outside the CO₂-focused monitoring
- Vent and flare streams, and whether abatement performance is measured across the period or assumed from a design specification
- Imported and exported heat and steam between units and across the fence
- Catalyst regeneration cycles, which are periodic and are lost inside an annual average
- Purchased intermediates and the data quality behind them, where an intermediate can carry more embedded emissions than the final conversion adds
What is examined
The evidence we will ask for.
- Mass balance across the plant with carbon in and carbon out, including carbon leaving in product
- Process-specific emission measurements for N₂O and CH₄ where the reaction generates them
- The allocation rule for co-products, documented before the period, with its justification
- Abatement system performance data across the period, including outages
- Heat and steam import and export records at the unit level
- Regeneration and turnaround records, and purchased intermediate data with its verification status
CBAM
What CBAM says about this sector specifically.
Hydrogen, ammonia and nitric acid are CBAM goods with their own aggregated goods categories. Hydrogen is direct emissions only and is a precursor to ammonia; ammonia is a precursor to both nitric acid and urea. If any of these leave your plant for the EU, the CBAM boundary applies to them regardless of what the rest of the site produces.
Scope note: CBAM verification accreditation has not been granted. Nothing here is offered as accredited CBAM verification before formal grant.

The normative frame
The standards the work runs under.
ISO 14064-1:2018 · ISO 14064-3:2019 · ISO 14067:2018 for product claims. Where an EPD is intended, ISO 14025:2006 with the applicable product category rules, on an ISO 14040:2006 and ISO 14044:2006 basis.
Scope position: Confirm the specific activity against Accreditation Schedule 1225009B at pre-engagement.
