Article 31 3.

The Commission shall adopt calculation and verification rules for a specific critical raw material if it has concluded, having considered the various relevant environmental impact categories, that the critical raw material concerned has a significant environmental footprint and that therefore an obligation to declare the environmental footprint of that critical raw material regarding the environmental impact categories referred to in paragraph 1, when placing it on the market, is necessary and proportionate to contribute to the Union’s climate and environmental objectives by facilitating the supply of critical raw materials with lower environmental footprint.
