Carbon footprint calculator
Estimate the supply-chain emissions of a biomass fuel for your route and volume, and compare them with the coal it replaces. Verified, shipment-specific figures accompany every GFTx quotation.

t CO₂e per year
| Biomass supply-chain stage | Assumption | t CO₂e / year |
|---|---|---|
| Collection & processing at mill | Diesel handling, drying, screening | 180 |
| Inland transport to port | Truck, 120 km average | 140 |
| Sea freight | Bulk vessel, Belawan → Gdańsk, ≈ 9,400 nm | 860 |
| Port handling & storage | Discharge, covered storage | 70 |

Factors follow published life-cycle inventories for biomass supply chains (the sources listed on the current GFTx calculator) and standard combustion factors for coal; sea-freight factors use vessel-class averages per tonne-nautical-mile. Factors, sources and the version date are stored as JSON in the site repository so every change is reviewed and versioned.
Palm kernel shell is a residue of palm oil milling; the carbon released at combustion was absorbed during growth and is reported separately from fossil emissions under common GHG accounting conventions. Supply-chain emissions are fossil and are counted in full.
The calculator gives an indicative comparison. Contractual GHG values follow the RED methodology and are calculated per shipment from measured moisture, calorific value and the actual voyage.
Indicative estimate for planning purposes with sample factors. Contractual greenhouse-gas values are calculated per shipment from measured data and delivered with the certificate of analysis.
