GWP (Global Warming Potential)
GWP stands for Global Warming Potential, a scale used to measure how much heat a specific greenhouse gas traps in the atmosphere over a set period of time, typically 20, 100, or 500 years, compared to carbon dioxide (CO2). CO2 is used as the baseline with a GWP of 1. For example, a gas with a GWP of 100 would trap 100 times more heat than CO2 over the same time period. This measurement helps scientists and policymakers understand the environmental impact of different gases, including those used as refrigerants in HVAC systems.
