BRIEF QUOTATION:
Enhanced Natural Sinks/Offsets
The annual exchange of CO2 between the atmosphere and the combined ocean and terrestrial biosphere
is extremely large compared to total annual anthropogenic emissions. This suggests that small
increases in the net absorption of CO2 in the global carbon cycle could have a significant effect on
changes in atmospheric greenhouse gas concentration.
Dissolved CO2 in the oceans is removed by the growth of phytoplankton, with plant decay products
settling to the deep ocean or ocean bed. When carbon is thus removed, it is ultimately replaced by
CO2 drawn from the atmosphere. Numerous concepts have been proposed for enhancing oceanic uptake of
atmospheric CO2.
An important component of terrestrial uptake of CO2 is tree and plant growth. Trees can remove
carbon from the atmosphere and sequester it in forests and forest products, whereas deforestation
reduces the amount of carbon sequestered. Through improved forest-management technologies,
substantial increases can be made in carbon sequestration by (1) halting deforestation, 2) expanding
forests and reforesting areas, and (3) increasing the stocks of carbon in existing forests.

BRIEF QUOTATION:
In the first of two major project selections the department expects to make this year in its carbon
sequestration program, DOE said it will provide $7.7 million to the laboratories over the next three
years to study innovations ranging from carbon dioxide filtering membranes to the development of
"biofilms" made up of carbon-converting microorganisms.
In seven of the eight projects, lab researchers will team with scientists from the private sector,
universities, or other agencies.
"Carbon sequestration is rapidly emerging as a promising third option for dealing with greenhouse
gas concerns -- joining energy efficiency and the greater use of low-carbon fuels such as natural
gas," said Assistant Secretary for Fossil Energy Robert W. Gee. "The initiative we are announcing
today will draw on expertise from across our national lab complex and the private sector to explore
an exciting array of possibilities for countering the buildup of global warming gases."
