Bio-char from pyrolysis the fastest route to draw down CO2 to safe levels, say experts

In Washington, Durwood Zaelke, president of the Institute for Governance & Sustainable Development, speaking at the Climate Change & Security At Copenhagen conference at Washington, outlines two fast-track options for mitigating CO2 impact. The first is to use the international ozone treaty to phase down black carbon soot  and non-CO2 emissions, such as HFCs.

The second strategy is the expansion on bio-sequestration through forest development, agriculture and the production of biochar. Zaelke said “Some scientists have noted that bio-sequestration appears to be the only current way to draw down CO2 concentrations to a safe level of 350ppm.” Biochar is a byproduct of a pyrolysis process that converts biomass into renewable fuels, and power.
