There has been a good deal of interest in the potential of marine vegetation as a sink for anthropogenic C emissions ("Blue Carbon"). Marine primary producers contribute at least 50% of the world's carbon fixation and may account for as much as 71% of all carbon storage. In this paper, we analyse the current rate of harvesting of both commercially grown and wild-grown macroalgae, as well as their capacity for photosynthetically driven CO(2) assimilation and growth. We suggest that CO(2) acquisition by marine macroalgae can represent a considerable sink for anthropogenic CO(2) emissions and that harvesting and appropriate use of macroalgal primary production could play a significant role in C sequestration and amelioration of greenhouse gas emissions.
