Emission factor from IPCC

Tier 1 emission factors for oil transport - CH4; Pipelines

World · Fugitive releases · Any year

Each m³ processed released to the air counts as 0.161 kg CO₂e, its 100-year warming potential under IPCC AR6. open-climate.ai worked this figure out from values published by IPCC, for use anywhere and in any year.

Where 0.161 comes from

Derived by open-climate.ai

open-climate.ai adds up the gases IPCC publishes, each weighted by its warming potential.

Reporting this cubic metre under the GHG Protocol

Scope 1 0.161

Gas that escapes from equipment you run is a direct emission, so it is your Scope 1.

Every horizon, every IPCC report

A warming potential rests on two choices: how many years of warming are counted, and which IPCC assessment report supplies the numbers. IPCC publishes one of these 9 cells; the other 8 read “Not published by IPCC”.

What this number covers

One step: the gas getting out. Nothing before or after it is counted.

  1. Released to the air

    Gas escaping from equipment, a process or a container, counted by the mass that gets out.

    Included1 m³ processed

  2. Warming over 100 years

    Heat trapped by that kilogram, compared with 1 kg of CO₂: its GWP100 from the IPCC's sixth report.

    Included× 0.161

  3. Your record

    1 m³ processed of gas released. The factor is per m³ processed that escapes, not per m³ processed held.

    = 0.161

Outside this boundary

  • Making the gas
  • Burning fuel

Producing the gas is a different factor, reported when you buy it (Scope 3, category 1). Fuel burned on site has factors of its own.

A warming potential, not a measurement

Nobody measured this number at a site. It is the warming caused by 1 kg of the gas over 100 years, divided by the warming of 1 kg of CO₂. It is the same wherever the gas escapes.

m³ processed released × 0.161 = kg CO₂e

From IPCC's record to a comparable factor

IPCC publishes the inputs; open-climate.ai computed this value from them. Here is each field as printed and what open-climate.ai made of it.
