Which factor is used to compare refrigerants and their environmental impact?

• A. Color
• B. Global Warming Potential
• C. Thermal conductivity
• D. Viscosity

Answer: (B)

Global Warming Potential is used to compare refrigerants by their climate impact. It measures how much heat a given amount of refrigerant traps in the atmosphere over a set period (usually 100 years) relative to the same amount of CO2. CO2 is defined as 1, so a refrigerant with a higher GWP traps more heat than CO2 over that time frame. This makes GWP the standard way to rank refrigerants in terms of their contribution to warming, guiding choices toward those with lower climate impact. Other factors listed—color, thermal conductivity, and viscosity—relate to appearance or physical properties and do not indicate environmental effects.
