Reducing Emissions from Deforestation, Forest Degradation, Conservation of carbon stocks, sustainable Management of Forest, and Enhancement of Carbon Stocks (REDD+) builds on reliable estimates of forest carbon stocks at the national level.

Methods to estimate national-level forest carbon stocks are either based in biome averages, forest inventories, or remote sensing (Gibbs et al. 2007). While direct remote sensing based approaches using LIDAR, Radar, or very high-resolution optical sensors show promising results at the subnational level (TOLLEFSON 2009), inventory based methods are still needed to calibrate new methods and to provide data required for other purposes.


Inventory based carbon stock assessment are either implemented using biomass expansion factors (the so called indirect approach mainly used in national forest inventories) or allometric equations as recommended by the IPCC Good Practice Guidance on Land Use Land-Use Change and Forestry (IPCC GPG-LULUCF 2003).  In practice, direct and indirect approaches are applied jointly as the use of expansion factors can provide alternate solutions where direct measurements might not be feasible (SAINT-ANDRÉ ET AL. 2007).

Together with our international Experts we are offering the planning and implementation of Field inventories to assess carbon stock and carbon stock changes. In addition we can support the measurement and calculation of damage factors in different Forest Management Units (e.g. certified, non-certified logging concession) to estimate carbon emissions caused by selective logging.
