What is the role of carbon ledgers in product lifecycle assessments lca

Carbon ledgers play a crucial role in product lifecycle assessments (LCA) by providing precise measurement and tracking of carbon emissions throughout the entire lifecycle of a product. This includes all stages from raw material extraction, manufacturing, distribution, usage, to disposal. By integrating carbon ledgers with LCA, companies can obtain detailed insights into the carbon footprint of each phase, enabling them to identify and mitigate emissions hotspots. This integration allows for more accurate and comprehensive environmental impact assessments, which are critical for developing sustainable product strategies. Moreover, carbon ledgers facilitate compliance with LCA standards such as ISO 14040 and ISO 14044, ensuring that assessments are consistent and reliable. The data derived from carbon ledgers can also inform eco-design, helping companies innovate and reduce the environmental impact of their products. Key Takeaway: Carbon ledgers are essential in LCAs for tracking emissions, ensuring compliance, and informing sustainable product innovation. Sources: ISO 14040, ISO 14044, EPA LCA.
