1,17E-044,27E-051,30E-09 3,86E-012,94E-08 7,65E+00MJ2The negative numbers here is traced back to supplier EPD data used in A1. A similar negative result in ADPM has been seen in other steel EPD’s where Worldsteel datasets has been used. The consensus is that the ADP Elements impact category has some uncertainties, and the negative result is due to system expansion and crediting of by-products (EAF Dust – dust from recycled material in an electric arc furnace) in the Worldsteel data set.GWP Global warming potential; ODP Depletion potential of the stratospheric ozone layer; POCP Formation potential of tropospheric photochemical oxidants; AP Acidification potential of land and water; EP Eutrophication potential; ADPM Abiotic depletion potential for non fossil resources; ADPE Abiotic depletion potential for fossil resourcesResource use Parameter RPEE RPEM TPE NRPE NRPM TRPE SM RSF NRSFA4A1-A33 1,10E+00 1,09E+00 2,19E+00 9,43E+00 4,02E-05 9,43E+00 5,45E-03 2,56E-05 2,37E-04
