EIM measures environmental impact in four different categories: Water and energy needs, chemical impact, and worker impact.
Based on a recipe description, the software works in 3 steps:
1 Quantification (for each of the categories)
2 Benchmark against an environmental threshold defined for each of the categories
3 Process classification and scored as average of the 4 categories, with equal weight on the final score.
Every company and brand can use the EIM for different purposes and therefore, they can decide whether to focus on individual categories or on the overall score.
