For instance, refrigerants are a big problem because these gases have an extremely high Global Warming Potential (GWP). This is a measure of how much one kilo of gas contributes to climate change:
– Carbon dioxide (CO2) has a GWP of 1, we use it as a reference point;
– Methane has a GWP of about 26, which means one kilogram of methane is as bad as 26 kilograms of CO2;
– The refrigerants in common use in Cambodia have GWPs between 1300 and 2000!
To put this in perspective, when you burn one litre of gas in your car, you emit about 2.5 kilos of CO2 into the air. If you release into the atmosphere the refrigerants from only one household AC (usually about 0,5 kilos), it has the same impact on the climate as burning 400 litres of gasoline!
So let’s go deeper into this problem and see how we can solve it.
