Topics: Energy

The emissions of acidifying pollutants (SO2, NOX and NH3) are each weighted by an acid equivalency factor prior to aggregation to represent their respective acidification potentials

Additional information

These factors are: w(SO2) = 2/64 acid eq/g = 31.25 acid eq/kg, w(NOX) = 1/46 acid eq/g = 21.74 acid eq/kg and w(NH3) = 1/17 acid eq/g = 58.82 acid eq/kg. For tropospheric ozone formation, the relative impact of the combined contribution of NOX, NMVOC, CO and CH4 can be assessed based on their tropospheric ozone forming potentials (TOFP). These are: 1.220, 1.000, 0.110 and 0.014, respectively. For particle formation, emissions are estimated using the following aerosol 'formation factors': primary PM10 = 1, NOX = 0.88, SO2 = 0.54 and NH3 = 0.64.
