A guide to global warming potentials (GWPs)

Energy Policy, 1993
Abstract In order to quantitatively compare the greenhouse effect of different greenhouse gases a global warming potential (GWP) index has been used which is based on the ratio of the radiative forcing of an equal emission of two different gases, integrated either over all time or up to an arbitrarily determined time horizon.

Experimental comparisons on a gas engine heat pump using R134a and low-GWP refrigerant R152a

, 2020
Gas engine heat pump (GEHP) is attracting increasing interests owing to the high heating efficiency. However, the refrigerants used in existing GEHPs present high global warming potential (GWP) values, facing the challenge to be phased out. In this work,

Hohes GWP nicht mehr erlaubt

HLH
Seit Januar greift die nächste Stufe der sogenannten F-Gase-Verordnung: In der Heizungs- und Klimatechnik ist die Verwendung von synthetischen Chemikalien mit einem Global Warming Potential (GWP) von mehr als 2 500 verboten – selbst für Wartung und Instandhaltung.
