Combustion of Fuels - Carbon Dioxide Emission

Calculate CO2 emission from fuel combustion using carbon content and energy content. Formula: qCO2 = (cf / hf) × (MCO2 / MC), where qCO2 is specific CO2 emission (kgCO2/kWh), cf is specific carbon content (kgC/kgfuel), hf is specific energy content (kWh/kgfuel), MCO2 is molecular weight of CO2 (44), and MC is molecular weight of Carbon (12).
