02 / THE READOUT
What the evidence says.
Environmental score
GREEN-SCORE · /100A broader experimental score from Open Food Facts. It combines a category life-cycle baseline with recorded product factors such as packaging, origins and production labels.
03 / THE WHY
What moves the score?
Numbers are Open Food Facts score points. They may not sum exactly if the score applies caps or other rules.
04 / THE CLIMATE ESTIMATE
Compare the category baseline.
kg CO₂e per kg food. These are category estimates from Agribalyse, not measured footprints of the individual packages.
THE IDEA
A better answer sometimes says “we don't know.”
Most shopping comparisons promise one green winner. Product databases have gaps, and a category average cannot measure every brand. Green or Guess? shows the score factors, flags missing data, and avoids a verdict when the comparison is weak.
