Briefings

A study by the Paul Scherrer Institute PSI demonstrates that four existing hybrid life cycle assessment methods can be simplified to two, enabling broader accessibility without requiring deep mathematical expertise. This framework aims to make environmental impact assessments more feasible for general use.

Key points

• Four established hybrid methods for life cycle assessment can be reduced to two established hybrid methods.
• The simplified framework requires no in-depth mathematical knowledge to perform analyses.

Context

Life cycle assessment is used to quantify the environmental impact of products and services and forms an important basis for political decisions. However, the necessary data is always difficult to capture completely.

Limitations

Evidence is limited to the PSI study; no specific product examples, geographic scope, or quantitative thresholds are provided. The study does not claim the methods are universally applicable or fully validated for all scenarios.
