GWP and ODP in refrigerants: what they mean

Two key environmental indicators for refrigerants are GWP and ODP.

GWP

Global Warming Potential indicates how much a gas contributes to global warming compared to CO₂.

ODP

Ozone Depletion Potential indicates the effect of a refrigerant on the ozone layer.

Why it matters

European and international legislation is gradually leading towards refrigerants with lower GWP and zero ODP.

Practical significance

The choice of refrigerant affects the design, safety, service, and future availability of equipment.
