GLEC Logistics Emissions Declaration
What GLEC Logistics Emissions Declaration Covers
The Global Logistics Emissions Council (GLEC) Framework provides the harmonised methodology for calculating greenhouse gas emissions from freight transport and logistics. It is the reference standard adopted by the EU in ISO 14083 and required by leading logistics providers and their customers including Amazon, Unilever, and the Science Based Targets initiative for Logistics.
The Global Logistics Emissions Council Framework was first published in 2016 to solve a fundamental problem in corporate carbon accounting: freight transport crosses multiple carriers, modes, and geographies, yet no consistent methodology existed for calculating and communicating the associated GHG emissions. The result was a proliferation of incompatible carrier-reported emission figures that prevented meaningful comparison, aggregation, or verification. The GLEC Framework established a harmonised set of emission intensity values (EIVs) by transport mode, fuel type, and vehicle class, and a standard calculation approach based on the weight-kilometre as the unit of transport work.
In 2023, the International Standards Organisation adopted the GLEC Framework as ISO 14083:2023 (Quantification and reporting of greenhouse gas emissions arising from transport chain operations), giving it the legal standing of an international standard. The EU CSRD and its ESRS standards reference ISO 14083 for transport-related Scope 3 calculations, and the standard is now cited in the EU's Sustainable and Smart Mobility Strategy. For logistics companies subject to CSRD — large 3PLs, shipping lines, and airlines — ISO 14083 reporting is a mandatory disclosure requirement from 2025 onwards.
For shippers and manufacturers, the significance of GLEC/ISO 14083 lies in the Scope 3 Category 4 (upstream transport and distribution) and Category 9 (downstream transport and distribution) reporting obligations under the GHG Protocol and CSRD. Most companies' freight emissions are material — for a globally sourced consumer goods brand, Category 4 can represent 5-15% of total Scope 3 emissions — yet many still report it using rough estimates or omit it entirely. Leading logistics providers now offer GLEC-certified emission data in their customer portals, and shippers are expected to use this data rather than defaulting to generic emission factors. Sustalium's GLEC module ingests carrier-provided emission data alongside TMS shipment records and calculates a GLEC-compliant emission total by mode, route, and reporting period.
