With ecoinvent, the Paul Scherrer Institute and its partners at ETH Zurich, ETH Lausanne, Empa and Agroscope have been running the world’s leading database for life cycle inventories for over ten years. The latest ecoinvent version 3 collects new data in areas such as electricity generation, agriculture, transport, mining and chemicals. In the power sector, which is significant for life cycle assessments, the database now covers over 80 per cent of the global production. And technology that has not been considered thus far such as enhanced geothermal systems is to be included in ecoinvent from now on. The result is more accurate ecological assessments of products and services
