**"Control of fossil-fuel particulate black carbon and organic matter, possibly
the most effective method of slowing global warming"(pdf)**

**Updates to "Control fossil-fuel particulate black carbon..." (pdf)
**In the update above, the 100-year climate response per unit mass emission of
f.f. BC+OM relative to that of CO2-C was estimated as 90-190. Below is an example
application of this function:

If 1 tonnes of f.f. BC is emitted and the emission ratio of OM:BC is 2:1 (the assumption used to derive the climate response function), the low-end equivalent CO2 emission over 100 years is

1 tonnes f.f. BC * (3 tonnes f.f. BC+OM / tonne f.f. BC)

* (90 tonnes CO2-C / tonne f.f. BC+OM) * 44 tonnes-CO2/ 12 tonne CO2-C = 990
tonnes-CO2

The high end is

1 tonnes f.f. BC * (3 tonnes f.f. BC+OM / tonne f.f. BC)

* (190 tonnes CO2-C / tonne f.f. BC+OM) * 44 tonnes-CO2/ 12 tonne CO2-C = 2090
tonnes-CO2
