1)The total of direct and indirect emissions is derived by truncating decimal points from each worksite’s direct and indirect emissions (Scope 1 & 2), which may result in discrepancies
2)The calculation boundaries for all categories are restricted to Pohang and Gwangyang Steelworks
① This is limited to purchased raw materials that have the most direct impact on steel production among purchased products (including iron ore, coal, and limestone, which together account for over 90% of usage).
② Calculated based on assets acquired by POSCO in 2023, including steel mill equipment and vehicles
③ Emissions are calculated using the carbon footprint from the energy used by the steelworks
④ ⑧ Emissions from transportation of certain sold products, based on the terms of delivery (cost of freight), have been reclassified (downstream → upstream)
⑤ Calculated based on commissioned waste from worksites, utilizing data from the government’s waste management system ‘Allbaro Sys.’
⑥ ⑦  Calculated from the business travel and commuting data of employees at Pohang and Gwangyang Steelworks
⑨ Calculated from the Scope 1 & 2 emissions of the lime calcination plant leased by POSCO FUTURE M among leased assets
⑩ Increase compared to the previous year is due to the inclusion of emissions data from other investment companies
