For the Fertilizers Sector CBAM Solution
Carbonaz supports the entire range of ammonia, nitric acid, urea and compound fertilizer production. N₂O emissions (GWP 273), the fertilizer-specific fixed 1% mark-up penalty and CBAM 2026 benchmark data are defined in the system. CN code series 3102 and 3105 are fully supported.
Product Types
All Products of the Fertilizers Sector
Customized calculation for every product, from the ammonia base to NPK blends.
Ammonia (NH₃)
Ammonia produced from natural gas reforming via the Haber-Bosch process. It is the base raw material for all other nitrogen fertilizers. It is the most carbon-intensive fertilizer process.
Nitric Acid (HNO₃)
Produced by the oxidation of ammonia with platinum catalysts. As a by-product, high-GWP N₂O (nitrous oxide) emissions are formed.
Urea (CO(NH₂)₂)
Produced by combining ammonia and carbon dioxide under high pressure. It is a widely used nitrogen source. Synergy can be created by using CO₂ from the ammonia process.
NPK Compound Fertilizers
Compound fertilizers containing nitrogen, phosphorus and potassium. Formulations in different ratios are produced in a combined granulation process. Ammonium nitrate or urea based.
Calculation Accuracy
CBAM 2026 Benchmark Data Built In
The EU Commission's official fertilizer benchmark values are defined in the system. Separate values are applied for ammonia and nitric acid.
| Product | Benchmark | Source |
|---|---|---|
| Ammonia | 1.522 tCO₂/ton | CBAM 2026 Benchmark |
| Nitric Acid | 0.582 tCO₂/ton | CBAM 2026 Benchmark |
Source: CBAM 2026 Benchmark (IR 2025/2620) · Carbonaz seed data available in the system
Sector-Specific Capabilities
Designed from Scratch for Fertilizers
N₂O (Nitrous Oxide) Emission Calculation
N₂O emissions from nitric acid production are calculated automatically. They are converted to CO₂ equivalent using the GWP 273 value. This is the most critical emission item in the fertilizer sector.
Fixed 1% Mark-up Penalty (Fertilizer Exemption)
For the fertilizer sector only a 1% mark-up is applied in all years (10-30% in other sectors). This exemption is applied automatically in the system.
Natural Gas Reforming (SMR) Tracking
For natural gas reforming, the basis of ammonia production, fuel consumption and process emissions are tracked in detail. A distinction between grey ammonia and blue ammonia is possible.
CO₂ Recovery Systems
The use of CO₂ from the ammonia process in urea production (recovery) is tracked. In-sector CO₂ use is taken into account in the emission calculation.
Full Support for CN Code Series 3102 and 3105
CN codes 3102 (mineral nitrogen fertilizers), 3105 (mineral compound fertilizers), 2814 (ammonia), 2808 (nitric acid) are defined in the system.
Pt Catalyst Performance Tracking
In nitric acid production, catalyst performance is critical for N₂O minimization. The system models the relationship between catalyst efficiency and emissions.
Ready for the Future of Green Ammonia
There is a separate recording logic for ammonia production with green hydrogen produced from renewable electricity (green ammonia). Ready today for the technology of the future.
Multi-Tier Raw Material Supply Chain
Collect data at unlimited depth from your raw material suppliers such as natural gas, phosphate rock and potassium salt.
Scope 2 Electricity Consumption
Electricity consumption for ammonia synthesis and the nitric acid process is tracked. The Türkiye grid emission factor (IEA 2025) is applied automatically.
Full CBAM Factor Transition 2026 → 2034
The 0.025 → 1.000 transition schedule is recorded in the system. A full projection combined with the 1% mark-up exemption.
Immutable Audit Trail · 7-Year Retention
Every data entry, every calculation and every report is recorded in a way that cannot be changed retroactively. Ready for SGS audit.
Native-Language Interface and Support
Your team works in their own language. The interface, terms, documentation and support are available in multiple languages.
Fertiliser Sector Exception
Mark-up Penalty Fixed at 1%
The fertiliser sector has a special exception under EU regulation. Unlike other sectors, the mark-up penalty applies at only 1% across all years.
| Year | Other Sectors | Fertiliser Sector |
|---|---|---|
| 2026 | +%10 | +%1 |
| 2027 | +%20 | +%1 |
| 2028+ | +%30 | +%1 |
This exception works in favour of fertiliser producers. Carbonaz applies this rule automatically, with no manual entry required.
