Global Logistics Emissions Council

What is GLEC?

GLEC drives widespread, transparent, and consistent calculation and reporting of logistics GHG emissions.

The Global Logistics Emissions Council (GLEC) is our program where companies and NGO’s are dedicated to drive widespread, transparent and consistent calculation and reporting of GHG emissions. The GLEC Framework was developed to offer multinationals and their suppliers a harmonized, efficient, and transparent way to calculate and report logistics emissions. This methodology framework allows our members and partners to accelerate their action to reduce greenhouse gas emissions and to collectively meet the Paris Climate Agreement.

The GLEC Framework version 2.0 has provided the principles upon which ISO 14083 has been based, which will serve as a formally recognized global standard for calculating GHG emissions from transport chains (including logistics and freight).

Organizations on their journey to freight decarbonization can become a member of Smart Freight Centre and join the SFC community. Members have access to a wide portfolio of initiatives and projects to help them collaborate to improve their GHG emission performance and supply chain economics. Membership unlocks solutions through several SFC programs, including Global Logistics Emissions Council (GLEC), Clean Cargo, Sustainable Freight Buyers Alliance (SFBA), and Clean Air Transport.

GLEC Framework

The GLEC Framework was the first global recognized methodology to calculate logistics GHG emissions and formed the basis for ISO 14083. It  remains the primary industry guideline to support implementation of ISO 14083, and is aligned with:

Greenhouse Gas Protocol

GHG Protocol establishes comprehensive global standardized frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Global Green Freight Action Plan

The goal of the Global Green Freight Action Plan is to enhance the environmental and energy efficiency of goods movement in ways that significantly reduce the climate, health, energy, and cost impacts of freight transport around the world.

CDP Reporting

CDP runs the global environmental disclosure system. Each year CDP supports thousands of companies, cities, states and regions to measure and manage their risks and opportunities on climate change, water security and deforestation.

The GLEC Framework serves as primary industry guideline how to implement ISO 14083:


ISO 14083

The International Standard offering the first universal method for logistics emissions accounting. A game changer for climate action, the forthcoming standard is expected to support the industry globally in its carbon reduction efforts.

SFC Conformity Assessment Scheme

We launched the SFC Conformity Assessment Scheme (CAS) in 2023, inviting Validation and Verification Bodies (VVBs) to apply. In this CAS, independent VVBs are approved by SFC after having demonstrated they are qualified for GHG verification, and their auditors undergoing customized training on ISO 14083 and a mandatory exam.

GLEC Publications

Measuring and Reporting the Carbon Footprint of Electric Freight Vehicle Operations: Whitepaper

This Whitepaper addresses the critical aspect of measuring and reporting greenhouse gas (GHG) emissions from electric vehicles in logistics. As the adoption of electric freight vehicles gains momentum, particularly in the US and the EU, understanding and accurately accounting for their carbon footprint is crucial. This Whitepaper provides essential guidance for logistics professionals, offering nuanced insights into lifecycle emissions calculation, specifically tailored to electric vehicles and electricity usage. This resource acts as a valuable supplement to the ISO 14083 and the GLEC Framework.

End-to-End Guidance

Smart Freight Centre , in partnership with over 30 leading global organizations, supported by the World Economic Forum, with McKinsey & Company providing analytical insights and advisory guidance, co-developed and released in January 2023 an actionable and implementable guidance to quantify the impact of GHG logistics emissions from supplier to final customer; an End-to-End Guidance.

Market Based Measures Accounting Framework

The Market Based Measures Accounting Framework explains how to apply a market based accounting approach to the quantification and reporting of transportation greenhouse gas emissions.

Fuel Emission Factors in ISO 14083

This report explains how the current emission factors for Europe and North America in ISO 14083 annex K were derived. The report also includes Europe and USA's updated fuel emission factor values based on ISO 14083 methodology, allowing for greater accuracy and reliability in emission calculations.

GLEC Participants

Our SFC Community Members support the GLEC mission through participation in GLEC projects. They work in partnership to influence the future direction and standards for logistics emissions reporting and reduction. The following SFC Community Members participate in GLEC projects:


GLEC is supported by a network of accredited calculation tools, programs and strategic partners that share our vision of a zero-emissions freight and logistics. Our Associates support the GLEC mission and work with Smart Freight Centre on guidelines, development and projects.
