emissions from fossil fuel and land use (human caused), vegetation & land
(natural) and ocean (natural). I use the term natural loosely, because the
sequestration rates for vegetation, land and ocean are likely higher because of
the high concentration of carbon created by anthropogenic (human caused) burning
of fossil fuels and land use (deforestation). Since Ocean sequestration
over what they emit causes acidification, we really need to balance our
individual emissions with vegetation and land. These figures do not
include the sequestration from some undetermined human method. So far, bio
char technology is the only method I see on the horizon that does not have huge
risk. </font></font></span></div>

1.66 tons of co2 emissions equivalent, we would not longer be adding GHG to the
atmosphere. I think it would be useful to recognize the level of
performance needed to become harmless to the climate. Beacause of the
delay in achieving this standard, we really need to be net negative.
However, conceptually I think this is a useful concept to understand.
