Emission factor from UNEP Ozone Secretariat, Refrigeration, Air Conditioning and Heat Pumps Technical Options Committee (RTOC) 2022

CFC-11 - tri­chloro­fluoro­methane

World · Fugitive releases · Any year

Each kilogram of trichlorofluoromethane released to the air counts as 6,410 kg CO₂e.

Value for trichlorofluoromethane, per kg leaked

6,410kgCO₂e/kg

Leak to air · GWP100

One value, for any year

UNEP sets no date window, so there is no year to pick.

Reference year 2022

Default: what search and the API return when you ask for nothing specific

1 kg leaked = 6,410 kg CO₂e

The same warming over 100 years as releasing 6,410 kg of carbon dioxide.

Refrigerant you topped up this year

1 kg= 6,410 kg CO₂e

No top-up records? Charge × yearly leak rate gives the kilograms.

Where 6,410 comes from

Published as one number

UNEP prints this factor as a single figure, with no parts to add up and no split by gas.

Reporting this kilogram under the GHG Protocol

Scope 1 6,410

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. UNEP publishes 3 of these 12 cells; the other 9 read “Not published by UNEP”.

What this number covers

One step: refrigerant leaving your equipment. Your records give the kilograms; the factor converts them.

  1. Refrigerant in your equipment

    The charge in a heat pump, air-conditioning unit or chiller. No emission while it stays in the circuit.

    Starting point, not counted

  2. Leak to air

    Refrigerant lost through seals and joints, during servicing, or in a failure. Counted as the kilograms you top up.

    Included1 kg

  3. Warming over 100 years

    Heat trapped by that kilogram, compared with 1 kg of CO₂, over 100 years.

    Included× 6,410

  4. Your footprint

    1 kg leaked, reported as CO₂e.

    = 6,410

Outside this boundary

  • Making the refrigerant
  • Recovery at end of life
  • Power the unit uses

Buying the gas is Scope 3, category 1, with its own factor, not this one.

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 leak happens.

kg leaked × 6,410 = kg CO₂e
