These Guidelines have been developed by OICA (International Organization of Motor Vehicle Manufacturers) and CLEPA (European Association of Automotive Suppliers) to provide a common understanding and practical guidance on the application of Life Cycle Assessment (LCA) to passenger cars and automotive parts. ACEA, part of OICA, was major contributor to the creation of these guidelines.
They are intended to facilitate a common basis among industry stakeholders and to support dialogue between industry, authorities and other relevant stakeholders regarding the calculation and interpretation of automotive carbon footprints.
Automotive LCA is a complex assessment that relies on evolving methodologies, assumptions and data from multiple stakeholders across global supply chains. The Guidelines therefore reflect the current state of industry knowledge and experience and are intended to evolve as methodologies, data availability and best practices develop. They may be subject to future updates, refinements and further interpretation as experience with their application increases. They are intended to support informed discussions and facilitate convergence where appropriate, while recognising the methodological challenges and uncertainties inherent to LCA. (....)
