The International Biochar Initiative (IBI) announces that the United Nations Convention to Combat Desertification (UNCCD) has submitted a proposal to include biochar as a mitigation and adaptation technology to be considered in the post-2012-Copenhagen agenda of the UN Framework Convention on Climate Change (UNFCCC).
Biochar is a fine-grained, highly porous charcoal that helps soils retain nutrients and water. The carbon in biochar resists degradation and can sequester carbon in soils for hundreds to thousands of years.
UNCCD proposes that biochar must be considered as a vital tool for rehabilitation of dryland soils: “The fact that many of the drylands soils have been degraded means that they are currently far from saturated with carbon and their potential to sequester carbon may be very high … making the consideration of Biochar, as a strategy for enhancing soils carbon sequestration, imperative.”
UNCCD also cites the ability of biochar to address multiple climate and development concerns while avoiding the disadvantages of other bioenergy technologies that deplete soil organic matter. Biochar restores soil organic carbon and soil fertility, reduces emissions from agriculture, and can provide clean, renewable energy.
Reduced deforestation is another biochar advantage cited by the UNCCD in their submitted proposal for including biochar in carbon trading mechanisms: “The carbon trade could provide an incentive to cease further deforestation; instead reforestation and recuperation of degraded land for fuel and food crops would gain magnitude.”
UNCCD proposes to include biochar in the Clean Development Mechanism (CDM), and to revise the rules to account for biochar as a permanent means of carbon capture. UNCCD also proposes adjusting the carbon offset rules to allow greater financial flows to help developing countries increase soil organic matter with biochar.
Overall, the potential magnitude of biochar as a climate mitigation tool is great. IBI Board Chair Dr Johannes Lehmann said, "Biochar production from agriculture and forestry residues can potentially sequester one gigaton of carbon in the world's soils annually by 2040. Using the biochar energy co-product to displace fossil fuel energy can approximately double the carbon impact of biochar alone."
IBI’s objective for the remainder of the UN meeting at Poznan is to interest more countries in proposing biochar for consideration as a mitigation and adaptation technology in the post-2012 Copenhagen process of the UNFCCC.
