CO₂ Emissions from Fuel Combustion Calculator

m_CO₂ = m_fuel · C% · (44.01 / 12.01).

Compute the mass of carbon dioxide produced when m_fuel kilograms of a fuel with carbon mass fraction C are completely combusted: m_CO₂ = m_fuel × C% × (44.01 / 12.01) ≈ 3.664 × m_fuel × C%. Used for energy-policy carbon-footprint accounting.
