The Share of Non-Renewable Biomass in Wood Fuel Production & Consumption by Bio-climatic Zones in Nigeria

According to new regulations in CDM and VER projects, only the non-renewable share of total biomass consumption (NRB) can be claimed in energy efficiency projects dealing with bio-energy. With regard to wood energy, the calculation of NRB compares the sustainable yield (the annual increment of woody biomass) with annual demand and losses (e.g. from bush fires) in the project area. In the case of northern states like Kaduna this procedure has to be modified, because the bulk of fuel wood originates from areas outside these states.
