Notwithstanding the fact that all trees sequester carbon, clearly some trees grow faster than others and are therefore better at sequestering CO2 than others.  The rules for establishing woodlands and the types of trees that can be planted are determined by regional guidelines specified by the appropriate national authority.  Furthermore, the underlying science used to evaluate the amount of sequestered CO2 by different tree species is evolving and accurate algorithms for every type are hitherto unavailable. Consequently, the platform will use a combination of generic algorithms that render conservative estimates of sequestered CO2 and species specific algorithms to more accurately determine sequestered CO2.  The platform will adopt increasingly more accurate species specific algorithms as the science evolves.
