Many of the refrigerants used in HVAC systems are greenhouse gases – often hundreds of times more powerful than CO2. So they’re subject to increasing limits and regulation, based on the global warming potential (GWP) of each refrigerant. Practically, these “F-Gas” rules affect your system in several ways, such as:

Bans on some uses of high-GWP refrigerants

Inspection and leak detection requirements

Advancing quotas based on GWP level, limiting refrigerant supply

CO2e means “carbon dioxide equivalent”. Where a refrigerant’s GWP measures its climate impact compared to the same amount of CO2, your CO2e is the total potential impact of all the refrigerant in your system – so it’s the refrigerant’s GWP multiplied by its charge.

This is important for two reasons:

A growing number of countries are introducing taxes based on CO2e

Your CO2e determines your inspection and leak detection arrangements.
