Metlen Energy & Metals scores 35/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified August 2026.

That places Metlen Energy & Metals joint 347th of 596 companies scored, and 14th of 22 in Energy Supply / Utilities.

Metlen operates 2GW+ of gas generation while adding 826MW of new fossil capacity in 2024, undermining its -30% by 2030 absolute emissions target. Emissions disclosures rely on intensity metrics rather than absolute data. Third-party verified operations (EU ETS, ASI certification) exist, but public absolute figures remain opaque.
