H. Schütz, MFA training workshop EW-MFA Training Workshop – 31. August 2007 Training Session: -Balancing items and NAS – Net Additions from Stock

H. Schütz, MFA training workshop Balancing items and NAS - Intro  Correct for inconsistent accounting of inputs and outputs to derive consistent material balance

H. Schütz, MFA training workshop Balancing items and NAS – Input side  Oxygen for combustion processes -> based on air emission data -> requires to account in addition for H content in energy carriers -> requires to account for net demand (less oxygen content of energy carriers)  Include real oxygen demand for production – steel production  Exclude CO2 emissions from cement and lime production (intrinsic CO2)  Oxygen for respiration - coefficients  Nitrogen for Haber-Bosch – estimate  Nitrogen for NO, NO2 emissions – feasible?

H. Schütz, MFA training workshop Balancing items and NAS – Output side  Water vapour from fuels -> requires to account for H2O content in energy carriers  Water vapor from oxidised hydrogen in fuels -> based on H accounted at input side  CO2 and H2O from respiration of humans and livestocks – coefficients
