Plastic food packaging has problems with chemicals - but some other advantages
ESD researcher Helene Wiesinger gave a public lecture (in German) on the advantages and disadvantages of plastic food packaging at the Treffpunkt Science City, ETH Zurich’s public science programme.
Sometimes only 20 model inputs out of few hundreds of thousands drive most of the uncertainty in life cycle assessment models
This new ESD-PSI study published in the Environmental Science & Technology journal has introduced a novel global sensitivity analysis (GSA) protocol that can aid in increasing robustness of life cycle assessment (LCA) results by improving data quality of only a tiny fraction of datasets. On the example of impacts from Swiss household consumption, we show how to efficiently conduct GSA for complete background LCA models, and consistently validate results.
