  "text": "1. Under the mass balance methodology, the operator shall calculate the quantity of CO2 corresponding to each source stream included in the mass balance by multiplying the activity data related to the amount of fuel or material entering or leaving the boundaries of the mass balance, with the fuel's or material's carbon content multiplied by 3,664 t CO2/t C, applying section 3 of Annex II.\n2. Notwithstanding Article 49, the emissions of the total process covered by the mass balance shall be the sum of the CO2 quantities corresponding to all source streams covered by the mass balance. CO emitted to the atmosphere shall be calculated in the mass balance as emission of the molar equivalent amount of CO2.",
