I hesitate to add to what is already a leviathan of a thread... but here goes. Assuming a carbon price were in effect, could coastal governments and landowners offset the cost of beach enhancement & sand replacement with CO2-sequestering sand? It would not have to optimally efficient to be substantial. On the face of it, getting permitted to use olivine on beaches seems a huge hurdle, but there is a already a tremendous amount of stirring-up of shallow coastal waters, budgeted and permitted. Transportation has already been arranged. Based on my familiarity of the Jersey Shore, coastal towns throw enough money at replacing sand that will quickly erode away, so why not put it to some long-term use? (Perhaps Atlantic City's unemployed croupiers can be sent out stirring the beaches). I have no idea how to calculate the potential scale, but perhaps this has already been done.
Convince homeowners' associations to link CDR to property values and you've harnessed an unstoppable force... And is dredging relevant here?
