Man-made industrial chemicals
Summary
- Sulphur hexafluoride (SF6), has a global warming potential (GWP) 22,200 times more powerful that of CO2. And it’s increasing (Video & Fig. 1).
- CFCs, HCFCs, HFCs, PFCs and others (Fig. 2) are man-made chemicals with a global warming potential many thousands of times that of CO2. Some contribute to the loss of the ozone layer. They have been linked to why the Arctic and Antarctic regions are warming faster than anywhere else on Earth.
- Collectively, they contribute 2.4% to NZ’s emissions.

Global Warming Potential (GWP):
Is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (CO2). This is sometimes written as eCO2 or e-CO2.
