Why the name Sandbag?

We came up with the name Sandbag because for us it symbolised a positive action people could take to protect themselves from natural disasters and flooding is likely to be increasing impact of global climate change. We also wanted a single word that would distinguish us from the many 'climate this' or 'carbon thats' there are already out there.

Only after we had launched, someone pointed out that sandbags are used as a safety control in hot air ballooning - 'hot air' is a term used in emissions trading to describe the permits that become spare through no actually effort on the behalf of the owner - ie they were given them wrongly in the first place. We like this. Sandbag is all about controlling 'hot air' in emissions trading.
