What Is ISO 14083?
ISO 14083:2023 is the official international standard for quantifying and reporting greenhouse gas (GHG) emissions from transport chain operations. Published by ISO in April 2023, it provides a consistent methodology for all transport modes — road, rail, inland waterway, maritime, and air.
ISO 14083 is directly based on the GLEC Framework v3.2 (Global Logistics Emissions Council), the industry-developed standard. The two are methodologically aligned: a calculation compliant with GLEC v3.2 is also compliant with ISO 14083:2023.
For EU freight carriers, ISO 14083 is the standard referenced in shipper sustainability requirements, CSRD supply chain reporting, and major retailer procurement frameworks from 2024 onwards.
WTW vs TTW: Why the Difference Matters
TTW — Tank-to-Wheel
Covers only the COâ‚‚ emitted when fuel is burned in the vehicle engine. Does NOT include the emissions from producing and transporting that fuel.
âš Not sufficient for CSRD / ISO 14083 reporting alone
WTW — Well-to-Wheel ✓
Covers the full fuel lifecycle: extraction, refining, fuel transport to the pump, AND combustion in the vehicle. This is what ISO 14083 and GLEC v3.2 require.
✓ Required for ISO 14083:2023 / GLEC v3.2 compliance
WTW emissions are typically 15–25% higher than TTW for diesel road freight. If your current CO₂ reporting only uses TTW, your numbers will be rejected by shippers for CSRD purposes.
How LogisticsAI Automates ISO 14083 Calculation
Instead of manually looking up GLEC emission factors in spreadsheets, LogisticsAI reads your TMS export CSV and automatically applies the correct GLEC v3.2 WTW emission factor for each shipment based on the vehicle type, transport mode, and load data.
What LogisticsAI calculates automatically:
- ✓Per-shipment CO₂e using GLEC v3.2 WTW factors for the correct vehicle type
- ✓Total transport chain emissions in tonnes CO₂e for the reporting period
- ✓Modal split: road, rail, sea, air — with individual emission subtotals
- ✓Intensity metrics: CO₂ per tonne-km and CO₂ per shipment
- ✓Methodology documentation: emission factors used, boundary conditions, calculation basis

Frequently Asked Questions about ISO 14083
What is ISO 14083?
ISO 14083:2023 is the international standard for quantifying and reporting greenhouse gas emissions from transport chain operations. It defines how to calculate COâ‚‚ equivalent emissions for road, rail, sea, and air freight, using standardised emission factors. It is aligned with and based on the GLEC v3.2 Framework.
What is the difference between WTW and TTW?
WTW (Well-to-Wheel) covers the full fuel lifecycle: extraction, refining, transport to the pump, AND burning in the vehicle. TTW (Tank-to-Wheel) covers only the fuel actually burned. ISO 14083 and GLEC v3.2 require WTW emissions — just reporting TTW is not sufficient for CSRD compliance.
What emission factor does the calculator use?
The estimator uses the GLEC v3.2 EU average road freight emission factor of 0.0895 kg COâ‚‚e per tonne-kilometre (WTW). Actual factors vary by vehicle type (rigid <7.5t, articulated >40t, etc.), fuel type (diesel, HVO, electric), and load factor. LogisticsAI applies the correct specific factor from your TMS data.
Is this calculator accurate enough for CSRD reporting?
The estimator provides an approximate figure for planning purposes only. For CSRD reporting, tender responses, or shipper submissions, you need an exact report generated from your actual shipment data with documented methodology. Upload your TMS CSV to LogisticsAI to generate a fully compliant ISO 14083 / GLEC v3.2 report.
What data do I need to generate a full ISO 14083 report?
You need a CSV export from your TMS (Transport Management System) containing: shipment dates, origin and destination postal codes (or distances in km), cargo weight per shipment, and vehicle type or mode of transport. LogisticsAI maps your column headers automatically — no reformatting required.
