What are the specific environmental and energy usage benefits of R-32?

R-32 has significantly lower Global Warming Potential (GWP) – one third that of R-410A. This means the refrigerant charge amount can be reduced by 10 to 30% over R-410A and the CO2 equivalent refrigerant charge (kg x GWP) can be drastically reduced. Also, compared with R-410A, R-32 transfers a larger quantity of heat-per-unit amount, producing greater efficiency, and requiring less electricity to operate.
