What this number covers

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

    • Fuel supply chain
    Included

  2. Production

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

  3. Also counted

    • Plant and equipment
    Included

  4. Your record

    = 0.0857

Outside this boundary

  • Installation
  • Maintenance
  • Transport to the border
  • Retail
  • Use
  • End of life
  • Recycling credit

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

Gases

Basis: Excl. biogenic CO₂FossilBio CH₄Land useBio CO₂GHG Protocol and IPCC inventories

  • Fossil CO₂0.082996.8%
  • Methane (CH₄)0.001892.2%
  • Nitrous oxide (N₂O)0.0008481%

Σ 0.0829 + 0.00189 + 0.000848 = 0.0855979, which GEMIS rounds to 0.0857.

Each gas is converted to CO₂e with AR6 100-year warming potentials; biogenic CO₂ and land-use carbon are left out, while methane from biogenic sources is counted.
