Fixed and Adjustable Baselines

A baseline can be determined by either assuming a fixed and steady state or using an adjustable or moving approach. The question to ask is whether the baseline established at the start of the project should remain constant throughout the project or be adjusted periodically, as described by the re-estimated baseline in Fig. 6.1a.

(i) A fixed-state baseline approach can be used where the carbon stock (line B(S)) is unlikely to change over the years (Fig. 6.1a). Highly degraded lands or agricultural lands with no change in use or management practice are unlikely to experience changes in carbon stocks. Further, any small changes in, say, soil organic carbon cannot be reliably measured. Thus, only a single measurement at the beginning of the project is adequate. Many CDM methodologies recommend the fixed baseline approach (http://cdm.unfccc.int). (ii) If carbon stocks are expected to change under the baseline scenario, it is more appropriate to adjust the baseline periodically and estimate carbon stocks at different periods (Fig. 6.1a). Use control plots in a proxy area outside the boundary of the project but subjected to the same conditions as those that obtain within the project plots for monitoring changes in carbon stock. The central argument for revising the baseline over the length of the project is that such revisions may ensure more realistic estimates of carbon stock changes; the central argument against is that a continual revision could involve additional costs and make projection of future carbon stocks a complex process.
