tCERs reflect the difference of carbon stock in the carbon pools in the project and baseline at the time
of verification less cumulative project GHG emissions within the project boundary less cumulative
GHG emissions outside the project boundary due to afforestation or reforestation difference in
carbon stocks in the carbon pools outside the project boundary (tCO 2 ), affected by afforestation or
reforestation activity, in the baseline and project at the time of verification, i.e,

lCERs reflect the difference of increment of the carbon stock in the carbon pools, between two
verification period, in the project and the baseline less project GHG emissions between two
verification period less GHG emissions outside the project boundary less difference of increment in
carbon stock in the carbon pools outside the project boundary (tCO 2 ), affected by afforestation or
reforestation project activity, in the baseline and project, i.e,
l-CER (tv) = [CP(tv) – CP(tv – K)] – [CB(tv) – CB(tv – K)] – ∑E(t) – ∑LE(t)
– [(LP_B(tv) – LP_B(tv – K)) – (LP_P(tv) – LP_P(tv – K))]
where:
t-CER(t v ) t-CERs emitted at time of verification t v (tCO 2 )
l-CER(t v ) l-CERs emitted at time of verification t v (tCO 2 )
CP(t v ) Existing carbon stocks at the time of verification t v (tCO 2 )
CB(t v ) Estimated carbon stocks of the baseline scenario at time of verification t v (tCO 2 )
E(t) Project emissions in year t (tCO 2 )
L E (t) Leakage: estimated emissions by sources outside the project boundary in year t (tCO 2 )
L P_B (t v ) Leakage: estimated carbon pools outside the project boundaries in the baseline scenario on
areas that will be affected due to the implementation of a project activity at time of verification t v
(tCO 2 )
L P_P (t v ) Leakage: existing carbon pools outside the project boundaries that have be affected by the
implementation of a project activity at time of verification t v (tCO 2 )
t v Year of verification
K Time span between two verifications
The EB agreed to the methodological tool for estimation of GHG emissions related to fossil fuel
combustion in A/R CDM project activities [EB33, Annex 14]. This tool allows for estimating increase
in GHG emissions (both project and leakage emissions) related to fossil fuel combustion (only CO 2
emissions) in A/R CDM project activities. The sources of emissions are: vehicles (mobile sources, such
as trucks, tractors, etc.) and mechanical equipments (e.g., portable equipment such as chain saws and
stationary equipment such as water pumps) required by the A/R CDM project activity.
