C400 – BS 8609:2014 C02 Emission Factor From Composition

Description

This calculation gives methods for the calculation of the carbon dioxide
emission factor of natural gases, natural gas substitutes and other combustible
gaseous fuels, when the composition of the gas by mole fraction is known. The
method provides for the calculation of the carbon dioxide emission factor at the
commonly used reference conditions of temperature and pressure and on the
four common quantity bases, mole, mass, volume and energy.
