This tool provides procedures to calculate project emissions from flaring of a
residual gas stream (RG) containing methane. This tool is applicable under the
following conditions:
• The RG to be flared contains no other combustible gases than methane,
carbon monoxide and hydrogen;
• The RG to be flared shall be obtained from decomposition of organic material
(through landfills, bio-digesters or anaerobic lagoons, among others) or from
gases vented in coal mines (coal mine methane and coal bed methane).
• Project emissions from flaring of the residual gas stream in year y (tCO 2 e)
[PE flare,y ]
• Flare efficiency in hour h based on measurements or default values [ηflare,h]
This methodological tool determines the CO 2 emission factor for the displacement
of electricity generated by power plants in an electricity system, by calculating the
“operating margin” (OM) and “build margin” (BM) as well as the “combined margin”
(CM). The OM refers to a cohort of power plants that reflect the existing power
plants whose electricity generation would be affected by the proposed CDM
project activity. The BM refers to a cohort of power units that reflect the type of
power units whose construction would be affected by the proposed CDM project
activity.
This tool may be referred to in order to estimate the OM, BM and/or CM for
the purpose of calculating baseline emissions for a project activity substitutes
electricity from the grid, i.e. where a project activity supplies electricity to a grid
or a project activity that results in savings of electricity that would have been
provided by the grid (e.g. demand-side energy efficiency projects).
Note that this tool is also referred to in the “Tool to calculate project emissions
from electricity consumption” for the purpose of calculating project and leakage
emissions in case where a project activity consumes electricity from the grid or
results in increase of consumption of electricity from the grid outside the project
boundary.
• Combined margin CO 2 emission factor for grid connected power generation in
year y (tCO 2 /MWh) [EF grid,CM,y ]
• Build margin CO 2 emission factor for grid connected power generation in year
y (tCO 2 /MWh) [EF grid,BM,y ]
• Operating margin CO 2 emission factor for grid connected power generation in
year y (tCO 2 /MWh) [EF grid,OM,y ]
II. AFFORESTATION AND REFORESTATION (A/R) RELATED TOOLS
Applicability
Parameter(s) to
be determined
• This tool provides for a step-wise approach to demonstrate additionality in A/R
CDM projects.
• Project participants proposing new baseline methodologies may incorporate
this tool in their proposal. Project participants may also propose other
approaches for the demonstration of additionality to the EB for its
consideration.
• In validating the application of this tool to a proposed project activity, DOEs
should assess credibility of all data, rationales, assumptions, justifications and
documentation provided by project participants to support the selection of
the baseline and demonstration of additionality.
Procedure: Project participants shall apply the following five steps:
• STEP 0. Preliminary screening based on the starting date of the A/R project
activity;
• STEP 1. Identification of alternative land use scenarios to the A/R project
activity;
• STEP 2. Investment analysis to determine that the proposed project activity is
not the most economically or financially attractive of the identified land use
scenarios; or
• STEP 3. Barriers analysis; and
• STEP 4. Common practice analysis.
• Forestation of the land within the proposed project boundary performed with
or without being registered as the A/R CDM project activity shall not lead to
violation of any applicable law even if the law is not enforced;
• The use of this tool to determine additionality requires the baseline
methodology to provide for a stepwise approach justifying the determination
of the most plausible baseline scenario. Project participants proposing new
baseline methodologies shall ensure consistency between the determination
of a baseline scenario and the determination of additionality of a project
activity; and
• This tool is not applicable to small scale afforestation and reforestation project
activities.
This procedure does not use its own parameters.
