HFC PHASE DOWN IN THE EU

 

 

CALCULATION OF CARBON DIOXIDE EQUIVALENT OF A QUANTITY OF F GAS

You need to find out how to express the mass of a fluorinated greenhouse gas (F gas) in terms of CO2 so that you comply with EU regulations on F gases.

Some EU requirements for fluorinated greenhouse gases (F gases) have size thresholds.

The size thresholds are expressed in terms of Carbon Dioxide (CO2) equivalent.

That takes into account how much a gas contributes to global warming, relative to carbon dioxide.

 

You calculate the carbon dioxide equivalent of a quantity of F gas by multiplying the mass of the gas (in tonnes) by the gas global warming potential (GWP)

You’ll usually find the mass of an F gas expressed in Kilograms (Kg) on product labels etc. To convert the mass to tonnes divide by 1000.

 

EXAMPLE CALCULATION:

The amount in tonnes of CO2 equivalent is the mass (in tonnes) of F gas multiplied by the global warming potential (GWP) of that F gas.

For Example

The global warming potential of HFC 404a is 3922. Therefore the tonnes CO2 equivalent of 10Kg of HFC404a is calculated as follows :-

 

  1. Mass (in tonnes) of F gas , multiplied by the global warming potential of F gas.
  2. = (10 / 1000) x 3922
  3. = 39.2 tonnes CO2 equivalent

 

KEEP RECORDS

The operator and the company that services it must keep detailed records of equipment checked for leaks

(i.e. any equipment that contains F gas equivalent to more than 5 tonnes of CO2)

You must also record if the gas used in the equipment has been recycled or reclaimed.

You must keep records for 5 years and make them available to government officials if they ask for them.

 

A.E.L. are able to service and maintain your equipment to meet all EU and F gas regulations.
