 - Companies have a growing need to calculate and report logistics emissions data with greater accuracy and transparency. They want to move from standard and modeled data to primary data that accurately reflects their supply chain emissions.
 - This document specifies a [[#data-model]] and the [=data transactions=] necessary for the interoperable exchange of primary logistics emissions data, ensuring that they are structured to facilitate the calculation of Product Carbon Footprints (PCFs).
-- Based on the [[!GLEC]] Framework and [[!ISO14083]], this technical specification adopts the format established by the PACT Framework and PACT Technical Specifications. It conforms to the basic semantics framework for the [SFC Data Exchange Network project](https://www.smartfreightcentre.org/en/our-programs/emissions-accounting/global-logistics-emissions-council/digitalization-program/sfc-exchange-network).
+- Based on the [[!GLEC]] Framework and [[!ISO14083]], this technical specification is built on top of the PACT Technical Specifications. In addition, it is based on the basic semantics and framework developed by the [SFC Data Exchange Network project](https://www.smartfreightcentre.org/en/our-programs/emissions-accounting/global-logistics-emissions-council/digitalization-program/sfc-exchange-network) and advances them further.
 - Adoption of this specification will enable the exchange of data between all actors in the logistics value chain, facilitating the calculation of emissions at the [=shipment=], [=Transport Chain Element|TCE=] and [=TOC=] levels, and the integration of these calculations at the [=PCF=] level.
 
 Advisement: The iLEAP Technical Specifications will be continuously refined as part of the ongoing iLEAP project. Significant changes may be introduced as the project progresses.
