Should the specific embedded emissions of aluminium/steel goods be determined separately for different alloy grades?

Specific embedded emissions are generally determined per aggregated goods category, unless different production routes are used in an installation. The aggregated goods categories may cover goods with different CN codes. Within the same CN code, the content of alloying elements or the share of input scrap may vary. Nevertheless, embedded emissions during the transitional period can be reported per aggregated goods category.

Operators may voluntarily choose a more disaggregated determination of specific embedded emissions for certain goods or groups of goods.
