This British Standard 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 (at the reference conditions of temperature and pressure); and
•energy (gross or net).
