Quantifying the emissions savings will require a baseline scenario.Out of the many alternatives, identify a baseline scenario where CDM project is not implemented. The baseline scenario should be viable project that meets all statutory and regulatory requirements. Baseline scenario can also be a project that gives a similar output in near identical situations.
Compare the emissions from the baseline and the CDM project. This gives the CO2 reductions from the CDM project.
E.g. Consider a CDM project that the uses landfill gas for power generation in a nearby industry.The baseline scenario will be
- the landfill gas is vented or flared.
- the industry sources the electricity from the power grid.
The emissions of GHG if we use the landfill gas for power generation and supply to the industry is compared with the baseline scenario to determine whether CDM is feasible or not. Also this is used to account for the CER's generated.
