Biofuelwatch claims a lot, but their agenda is not reality and overlooks novel findings from recent science.
For instance a recent nature study finds: Sustainable biochar to mitigate global climate change we estimate the maximum sustainable technical potential of biochar to mitigate climate change. Annual net emissions of carbon dioxide (CO2), methane and nitrous oxide could be reduced by a maximum of 1.8 Pg CO2- C equivalent (CO2-Ce) per year (12% of current anthropogenic CO2-Ce emissions; 1 Pg=1 Gt), and total net emissions over the course of a century by 130 Pg CO2-Ce, without endangering food security, habitat or soil conservation. Biochar has a larger climate-change mitigation potential than combustion of the same sustainably procured biomass for bioenergy, except when fertile soils are amended while coal is the fuel being offset. http://www.nature.com/ncomms/journal/v1/n5/full/ncomms1053.html Gaia Foundation and Biofuelwatch seem to be spreading lies in africa: telling that small scale biochar stoves poison air, people and plants.... http://groups.google.com/group/biocharindia/browse_thread/thread/799b39e2bb879a11 There is no science to support the claims from Biofuelwatch or the Gaia Foundation both are some ill advised projects which motives are very weird. > > http://www.biofuelwatch.org.uk/docs/Biochar-%20A%20Critical%20Review%... > > A common vision amongst > biochar supporters is that it should be scaled up to such a large > scale that it can help to reduce or > stabilise atmospheric concentrations of carbon dioxide. > Research to date on biochar has had mixed results and clearly > indicates that biochar is not one > product but a wide range of chemically very different products which > will have very different effects > on different soils and in different conditions.
