Dear Ecoinvent forum,
where can I found a reference / document explaining the main differences between the life cycle inventory data of PlasticEurope and Ecoinvent ? For instance, the GWP of EPS is roughly double CO2eq/kg resin in Ecoinvent 3.5 (the unit model "allocation, recycled content / cut-off....cradle to gate production, RER), compared to the CO2eq/kg (Ecoprofile of Expandable Polystyrene (EPS) PlasticsEurope February 2015). Where dose this GWP difference come from ?
Thank You
Stefano
