Even if they did survive - where is the public and verifiable information on how much carbon is stored in mallees ? I'd like to know the per hectare potential for mallee carbon storage, so I can get a rough idea of the companies possible cashflow (having made some reasonable assumptions about carbon price etc). I saw the MD on a re-run of a Landline show yesterday, and thoughts of used cars and canal developments did spring to mind.
