How it's built
Each material in this library is scored across 20 ecological mechanisms - not general sustainability categories, but specific physical pathways: the cargo ship noise that prevents a whale from hearing her prey, the chrome plating bath draining near a salmon river, the microplastic in the egg of a seabird that has never been near a city.
Most certifications tell you what's safe for the person inside. This library tells you what happens to the animal outside.
