Carbon sponge

A carbon sponge would be a natural or man made technology that is able to absorb carbon emission (from a fuel burning plant, for example) or from the atmosphere itself. The most common example of a naturally occurring carbon sponge are forests. Forests, by their very nature, pull carbon from the atmosphere as an essential building block and replace it with oxygen in the atmosphere. There is some evidence that man made materials might also prove effective. Pores of carbon sponge materials would be precisely controlled at the nanometer scale to make the most efficient carbon sponge.
