Three B-Wedge Scenarios5.8 Closing RemarksBiochar analysis remains a very complicated topic. Despite enormously rapid progress over the last few years,important unanswered questions abound. There is ignorance about Biochar’s existence by most policy analysts –even those active in energy, climate and soil areas. This should not be surprising, given almost no governmentalfunding.Nevertheless, we conclude that Biochar could become THE major carbon-negative technology in both the UnitedStates and the world. It also seems likely to become one of the top three carbon-neutral supply sources as well(supporting solar and wind to be even larger than without Biochar). No major impediments for large scale introductionfor Biochar have surfaced – save that of adequate incentives. Although there are upper land limits to itsintroduction, those limits do not now look insurmountable. The necessary biomass resource (about 4 B-wedgesin the US and 40 B-wedges globally) seem to be available, if the political will is there.Thanks are especially offered to Mr. Jonah Levine who suggested the topic and provided editorial guidance.Also thanks to many Biochar friends, especially those at the Yahoo “Biochar-policy” list, and those met at severalBiochar conferences over the past three years. who have helped hone the ideas expressed here.Biochar GHG reduction accounting in: Potential Biochar Greenhouse Gas Reductions65
