E.2. Calculation of project emissions or actual net GHG removals by sinks
As per the methodology ACM0002 (version 13.0.0), for most renewable energy project activities,
the project emissions are zero (PEy = 0). However, for hydro power plants that result in new
reservoir (the JHPP case), the project emissions shall be calculated as follows:
PEy = PEHP,y
Where:
PEy = Project emissions in year y (tCO2e/yr);
PEHP,y = Project emissions from water reservoirs of hydro power plants in year y
(tCO2e/yr).
For hydro power project activities that result in new single or multiple reservoirs and hydro power
project activities that result in the increase of single or multiple existing reservoirs, project
proponents shall account for CH4 and CO2 emissions from the reservoir, estimated as follows:
(a) If the power density (installed power generation capacity divided by the flooded surface
area) of the single or multiple reservoirs (PD) of power plant is greater than 4 W/m2 and
less than or equal to 10 W/m2:

PEHP,y = Project emissions from water reservoirs (tCO2e/yr);
EFRes = Default emission factor for emissions from reservoirs of hydro power plants
(kgCO2e/MWh);
TEGy = Total electricity produced by the project activity, including the electricity supplied to the
grid and the electricity supplied to internal loads, in year y (MWh).
(b) If the power density (PD) of the power plant is greater than 10 W/m2:
PEy = 0
The power density of the project activity is calculated as follows:

Where:
PD = Power density of the project activity, in W/m2;
CapPJ = Installed capacity of the hydro power plant after the implementation of the project
activity (W);
CapBL = Installed capacity of the hydro power plant before the implementation of the
project activity (W). For new hydro power plants, this value is zero;
APJ = Area of the single or multiple reservoirs measured in the surface of the water, after
the implementation of the project activity, when the reservoir is full (m2);
ABL = Area of the single or multiple reservoirs measured in the surface of the water,
before the implementation of the project

As Vernadsky realized about 100 years ago, life (powered by photosynthesis and carbon cycling) is the most potent geologic force. Carbon cycling (which heavily influences water cycling) underlies almost all of our biggest challenges. Many now realize that humans have become a principle influence on carbon and water cycling, but our influence has been largely inadvertent, and often (e.g. changes in soil carbon in specific places) outside our awareness.
Comme l’a découvert Vernadsky il y a approximativement un siècle, la vie (générée par la photosynthèse et le cycle du carbone) est la plus puissante des forces géologiques. Le cycle du carbone (qui influence fortement le cycle de l’eau) est la principale force derrière tous nos plus importants défis. Plusieurs réalisent aujourd’hui que l’humanité est devenue la principale influence sur les cycles du carbone et de l’eau, mais notre influence s’est produite largement par inadvertance, et souvent (e.g. la diminution des niveaux de carbone des sols) en dehors de notre connaissance.
