On 1st July 2012 the Carbon Tax came into force and I’m going to try and explain the implications for air conditioners. Without putting too fine a point on it, we’ve been robbed!
The carbon tax is based upon the Global Warming Potential of various synthetic gases as defined by the International Panel on Climate Change AR2 1995 report. Put simply each gas is assessed against CO2 (carbon dioxide) as to its’ potential for global warming, and this figure is then applied to the carbon tax rate to determine how much tax should be paid. The initial rate for the tax has been set at $23 per tonne.
So for example let’s look at a mid range residential air conditioner suitable for a single room or area. This might have 2 kgs of R410a gas and the calculation would be as follows…
2kgs = 0.002 tonnes x $23 x 1725 (GWP for R410a)
So the carbon tax payable for this would be $78.35
Here are some popular gases and their GWP figures.
Carbon tax rates per refrigerant
|Refrigerant||Global Warming Potential|
Using this information we can gauge the carbon tax payable on residential air conditioners. In the table below I have listed the latest L series models from Daikin, together with their pre-charge amount of refrigerant gas and the carbon tax applicable. All gas in this example is R410a.

Not exactly cheap I think you’ll agree.
