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.
