Where 2.82 comes from

Derived by open-climate.ai

Σ 2.82: worldsteel prints the two parts separately; open-climate.ai adds them up. Benefit of recycling (D) stays beside it.

What this number covers

What worldsteel counts in the figure for one kilogram, phase by phase.

    • Transport to the plant
    • Raw materials
    • Fuel supply chain
    Included

  2. Production

    • Fuel combustion
    • Manufacturing
    • Packaging
    • Purchased electricity and heat
    Included

  3. End of life

    • End of life

  4. Your record

    1 kg in your records. The factor is per kg.

    = 2.82

Outside this boundary

  • Retail

worldsteel does not count any of this in the figure for one kilogram.

Gases

  • Fossil CO₂e2.82
  • Biogenic CO₂e0.0026

The total counts fossil CO₂e. worldsteel reports biogenic CO₂e separately; it is shown beside it, not added.

From worldsteel's record to a comparable factor

worldsteel publishes the two parts; open-climate.ai added them up to this total. Here is each field as printed and what open-climate.ai made of it.

The total and its parts

Each part has its own page, with its own years and source record. Never add a part to the total.

About this factor

From worldsteel

Obtained by electro plating a thin finished cold rolled coil with a thin layer of tin. It can be found on the market in coil or in sheets and is further processed into finished products by the manufacturers. Tin plated steel is used primarily in food cans, industrial packaging (e.g. small drums). Typical thickness between 0.13 - 0.49 mm. Typical width between 600 - 1100 mm.
