Avoid Carbon Emissions About 22% of the world ’ s total energy are utilized just in the United States, which has only 4.5% of the world ’ s population (USCB 2007) North Americans consume more than twice as much energy (per capita) than Europeans (7,943 and 3,773 kg of oil equivalent respectively http://earthtrends.wri.org)
Each year, the USA population uses three times more fossil energy than the total solar energy captured by all the plants in the USA per year ( Pimentel et al. 2009) In the USA, only 1% to 2% home heating is achieved with wood (USCB 1990).

Sequester Carbon
What is Sustainable Biomass? Example Slash and Char 1.31 Pg yr -1 (billion tons) of biomass is cleared in all secondary forests (fallow vegetation) (Fearnside 2000, Climatic Change)Is secondary forest re-growing biomass? Should forest re-grow and increase the stock in living biomass? Can living biomass be utilized for biochar carbon sequestration? Under which conditions? Alternative to fire?

Half-life of biochar? Keith Harris, kharris@engr.uga.edu
Trade in Emissions Reducations Is biochar different? Is the carbon value of biochar more than that of charcoal used to substitute fossil fuel? Additionality? Is biochar additional as it will always compete with charcoal?
