This project deliverable, LEARN D4.4 Testing Results, reports on the work carried out in LEARN WP4 on Testing and Validation. LEARN WP4 has tested, validated and evaluated the practical applicability of the agreed framework for harmonized greenhouse gas (GHG) emission calculation (GLEC Framework v1.0) and the eco-label concept in complex logistics settings. Earlier work of LEARN WP4 has defined research questions that need to be answered in WP4 during testing and validation. The research questions can be found in LEARN Deliverable D4.1. The process of testing is specified in LEARN Deliverable D4.2, LEARN D4.3 provided interim testing results. The current deliverable provides the final report on the LEARN testing and validation activities. The deliverable reports on feasibility and applicability of GHG calculation methods, their compatibility and consistency, provides insides on ecolabel design and future developments towards carbon accounting based on primary data at shipment level, reports on experience with direct data exchange between logistic and supply chain partners for calculation as well as reporting of GHG emissions.
