摘要
We propose the sequestering of crop residues to capture a significant fraction (12%) of the present U.S. atmospheric carbon emission through disposal in deep oceans below the thermocline or in river deltas. In the United States, the annual carbon content in residues from corn, soybeans and wheat crops is approximately 250 million tonnes. Globally, an additional 1 billion tonnes of carbon in the form of crop residues may be available. Implementation of this sequestering proposal would allow the US to approach the CO2 reductions stipulated under the Kyoto Protocol.
