ERy Emission reductions during the year y[t-CO2/year] BEy Baseline emissions during the year y[t-CO2/year] PEy Project emissions during the year y[t-CO2/year]
BEy Baseline emissions during the year y[t-CO2/year]
BEheat,y Baseline heat emissions during the year y [t-CO2/year] BEelec,y Baseline emissions from electricity generation during the year y [t-CO2/year]
BEy = BEheat,y + BEelec,y
<Prject emissions>
PEPJ,y = FCPJ,y × CVPJ,y × EFPJ,y
PEPJ,y Project emissions during the year y [t-CO2/year]
FCPJ,y Quantity of project flue combusted during the year y [m3/year]
CVPJ,y Net calorific value of the project fuel combusted during the year y [GJ/m3] EFPJ,y CO2 emission factor of the project flue combusted in the year y [t-CO2/GJ]
(ⅰ) Calculation from the efficiency of the equipment
BEheat,y = HGPJ,y× ×EFBL,y

ηBL
BEheat,y Baseline heat emissions during the year y [t-CO2/year] HGPJ,y Utilized waste heat amounts which supplied from
cogeneration equipment during the year y [GJ/year]
ηBL Energy efficiency of heat supply equipment in the baseline [%] EFBL,y CO2 emission factor of a fuel which is used for the equipment in the baseline [t-CO2/GJ]
(ⅱ) Calculation from Quantity of production(if heats are used all over the plant)
BEheat,y = PDPJ,y × FCBL/Pr,y × FCBL,y × EFBL,y
BEheat,y Baseline heat emissions during the year y [t-CO2/year] PDPJ,y Quantity of production in the project activity during
the year y [units/year, t/year]
FCBL/Pr,y Unit fuel consumption of a product in the baseline [m3/t or unit] FCBL,y Net calorific value of the fuel in the baseline [GJ/m3]
EFBL,y CO2 emission factor of a fuel which is used for the equipment
BEelec,y Baseline emissions from electricity generation during the year y [t-CO2/year] ELPJ,y Baseline emissions during the year y [t-CO2/year] EFBL,y Baseline emissions from electricity generation
