Economic consequences of consideration of permanence, leakage and additionality for soil carbon sequestration projects

This paper introduces, explains and describes the methods for addressing the issues of permanence, leakage and additionality (PLA) of agricultural soil carbon sequestration (ASCS) activities at the project level. Further, it evaluates methords for identifying and estimating PLA and guages the potential magnitude of these effects on the economic returns to a project.
