    1)  The sum of emissions by business site may differ from the reported total, as Scope 1 and Scope 2 emissions are aggregated after truncation of decimal places
         at the site level.
    2) Total Scope 3 emissions are calculated as the sum of emissions across all applicable categories and may therefore differ from the aggregate of upstream and
         downstream Scope 3 emissions.
    3) The calculation boundary covers Pohang and Gwangyang Works in 2023 and all business sites from 2024 onward.
         ① Limited to purchased raw materials with the greatest impact on steel production, including iron ore, coal, and limestone, which together account
              for more than 90% of total raw material consumption.
         ② From 2024 onward, emissions associated with certain supplies and vehicles acquired as POSCO assets are calculated using product carbon footprint data 
              certified under Korea’s Environmental Product Declaration (EPD) program.
         ③ Emissions from energy consumed at business sites are calculated using carbon footprint factors from the Environmental Product Declaration assessment
              factors published by the Korea Environmental Industry & Technology Institute (KEITI).
         ④,⑥ Transportation emissions associated with certain sold products are included in upstream transportation and distribution, depending on the applicable
                  delivery terms and freight payment responsibility.
         ⑤ Emissions are calculated based on the amount of waste generated at business sites and treated outside the organizational boundary, using data from Allbaro,
              Korea’s national waste management system.
         ⑦ Emissions are calculated based on Scope 1 and Scope 2 emissions from the lime calcination facility leased by POSCO FUTURE M and classified as a leased asset."

    1)Energy consumption is calculated on a company-wide basis using data disclosed in the Greenhouse Gas Emissions and Energy Consumption Statement, excluding renewable energy purchases. Minor discrepancies may occur due to the aggregation of figures after truncation of decimal places.

    2)At POSCO, coal is used as a reducing agent in the ironmaking process and is therefore excluded from energy consumption. Process-generated gas used as an energy source is included in by-product gas consumption.

    3)Electricity consumption is converted to energy consumption using a factor of 3.6 GJ/MWh, which represents the conversion factor for electricity consumed by the final energy user. Total electricity consumption excludes renewable electricity purchases and self-generated electricity.

    4)Self-generated and self-consumed renewable energy, including rooftop solar photovoltaic systems and building-integrated photovoltaics (BIPV), is converted from MWh to GJ using a factor of 3.6 GJ/MWh.

    5)The renewable energy utilization rate is calculated by dividing total renewable energy use and purchases, including Renewable Energy Certificates (RECs) and Green Premium purchases, by total energy consumption."
