Thanks for sharing the whitepaper. Cool to know there’s ‘lower carbon’ aluminium. However it still wasn’t clear to me WHY their aluminium has a GWP of 8 CO2e/kg of AL or less and what assumptions they’ve used in their figures (i.e. does it include transport to site impacts? What are the recycled content & EoL recycling assumptions? etc).
According to our default dataset, 1kg of extruded aluminium has a life cycle GWP of 10.4kg/yr at industry average 35.33% Recycled Content, 57.33% EoL Recycling Rate including transportation impacts on- and off-site and end of life impacts.
I hope that gives you a rough idea on what the approx GWP figures are for the default dataset aluminium.
