Pumice has a Zero Carbon Footprint.  Minimal energy is required for simple screen grading, solar drying & packaging. Distance to Perth is just 3,175 Nautical Miles. 

Compare this to glass which requires nearly half a litre of petroleum equivalent energy value, for each kilogram of glass products produced, energy needed to raise the temperature of both new and recycled glass to 1,575 degrees C the melting/forming temperature. That is not GREEN.   Distance from LA to Perth is  16,666 nautical miles over 5 times more transport energy required than Pumice.
