What Is GWP and Why Does It Matter for Refrigerants?
When we talk about cooling systems, refrigeration, air conditioning, or cold storage, we often get to hear the term GWP. But what does GWP actually mean? GWP stands for Global Warming Potential. In simple words, it tells us how much a greenhouse gas can lead to global warming compared with carbon dioxide (CO₂). CO₂ is used as the reference gas, so its GWP is 1. A refrigerant with a higher GWP can have a greater impact on the climate if it is released into the atmosphere. Why Is GWP Important for Refrigerants? Refrigerants are an important part of cooling systems. They help remove heat and keep systems such as air conditioners, cold rooms, chillers, freezers, and cold storage facilities cool. Normally, the refrigerant stays inside the system. But leaks, poor servicing, or improper disposal can release refrigerants into the atmosphere. This is where GWP becomes important. For example, some older refrigerants have a high GWP. If they are released into the atmosphere, their impact on globa...
