ISO 14083:2023 is the international standard for quantifying and reporting GHG emissions from transport chain operations. It applies to all modes (road, rail, air, sea, inland waterways, logistics hubs) and all actors (shippers, carriers, logistics service providers). It is the reference methodology behind the GLEC Framework v3 and the upcoming EU CountEmissionsEU regulation.
What is the GLEC Framework?
The Global Logistics Emissions Council (GLEC) Framework, maintained by the Smart Freight Centre, is the industry implementation guide for ISO 14083. Version 3 (2023) is fully aligned with ISO 14083 and provides default emission factors, energy intensity data and reporting templates for each transport mode.
What is the difference between WTT, TTW and WTW emissions?
Well-to-Tank (WTT) covers upstream fuel/electricity production. Tank-to-Wheel (TTW) covers combustion on the vehicle. Well-to-Wheel (WTW), or Well-to-Wake for ships/planes, is the sum of both and is the reference boundary under ISO 14083. GHG Protocol Scope 3 Category 4 and 9 use WTW as well.
Who uses ISO 14083 reports?
Shippers need ISO 14083 emission data from logistics providers to complete their Scope 3 Categories 4 (upstream transport) and 9 (downstream transport). Freight forwarders and carriers provide the data to customers. Many large retailers and manufacturers now require ISO 14083 / GLEC-aligned data from their logistics suppliers as a condition of procurement.
What is CountEmissionsEU?
CountEmissionsEU is the proposed EU regulation establishing a common framework for measuring and reporting transport-related GHG emissions across all modes, based on ISO 14083. Once adopted, it will make ISO 14083-aligned emission data mandatory for transport services in the EU, with particular importance for passenger and freight carriers.
Can Formist calculate ISO 14083 emissions from my TMS export?
Yes. Formist reads freight shipment records, routing data and fuel/energy consumption (or defaults from GLEC v3) to compute per-shipment and aggregated transport chain emissions by mode, energy carrier and data quality tier, and exports the filled SFC CAS Emissions Report (ASU-TPL-011-2 v02).
