The decarbonization of economic activities is one of the demanding global policies implemented to significantly reduce the impact of greenhouse gas emissions. While three main sectors are primarily targeted as the most polluting – namely metallurgy, chemicals, and the cement industry – many other sectors are also concerned by this objective, and multiple solutions are emerging.
These solutions are often still in development and combine the integration of new technologies into existing processes with the partial use of recycled materials. To properly assess their true relevance and avoid rebound effects, Life Cycle Assessment (LCA) appears to be one of the most appropriate tools for evaluation.
However, most LCA methodologies currently in use follow sector-specific standards, allowing for a certain degree of flexibility in their application, which prevents full consistency in calculations. These methodologies are also challenged by the ex ante evaluation of immature processes, for which data remains fragile. It is therefore necessary to complement them with calculations—particularly of the carbon footprint—that should be standardized and made more robust. For instance, there is currently no consensus within the sector on how to calculate the carbon footprint of recycled metals.
This session will explore—through examples from key industries—the methodological advances developed to address these challenges.
