What is the usual choice of "Metrics" for a Lifecycle-Based-Design Assessment?

In a Lifecycle-Based Design Assessment, the usual choice of metrics revolves around the use of primary data for accurate and reliable evaluations. Primary data encompasses information gathered directly from relevant sources involved in the lifecycle of a product, such as manufacturing processes, material extraction, and end-of-life disposal. This data is often specific to the particular product being assessed and allows for a more nuanced understanding of its environmental impacts.

By relying on primary data, the assessment can yield precise insights into resource use, energy consumption, emissions, and waste generation throughout the product’s lifecycle. This granularity is crucial for identifying specific areas for improvement, guiding design decisions effectively, and ensuring that sustainability measures are directly aligned with actual practices.

In contrast, other metrics might rely on estimates or qualitative assessments that may not provide the same level of specificity or accuracy. Standardized global metrics might be useful for broad comparisons but may lack the detail required for lifecycle assessments of specific products. Ultimately, using primary data enhances the effectiveness of lifecycle assessments in achieving sustainability objectives.
