“MF” provides a consumption perspective of resource use and new insights into the actual resource productivity of nations, including all chains.

3 Pros:

• Despite the principal incomparability of diverse materials, MF still provides one sober number
• Systemic comparability of production systems is thus allowed on a quantitative basis for all
• Effectivity of matter usage across all economic sectors (in all countries) is a helpful descriptor

3 Cons:

• The extreme care when interpreting such highly aggregated data is easily forgotten
• No toxicological differentiation of materials
• No differentiation into (un)protected usages
