A footprint says what your portfolio does to the environment. Risk says what the environment is going to do to your portfolio: the physical hazards facing the places your ingredients come from, projected forward.

The portfolio risk score
A single percentage with a band: low, moderate, high or critical. It is composed from per-product risk scores, weighted by volume, so a hazard facing a product you sell in quantity counts for more than the same hazard on one you barely ship.
The panel says how many products it covers. A product with no risk score is excluded rather than counted as zero, and the count is how you tell the difference.
Products by risk level
The distribution behind the headline: how many products sit in each band. A moderate portfolio average with eleven products in the high band is a different situation from one with none, and the average alone will not tell you.
Hazards
Risk is scored across hazards including flood, drought, frost, wildfire and water stress. Each is scored where your ingredients are actually sourced, which is why sourcing country matters to this number.
The largest single hazard is called out by name, because the response to frost exposure is not the response to water stress.
Trend against baseline
The trend compares your frozen baseline snapshot against the same products at their latest risk scores, so what you are reading is genuine movement rather than the effect of adding products since.
Hazards scored on only one side show as no movement rather than a movement from zero. A hazard that was not scored at baseline has not gone from nothing to something, it has gone from unknown to known, and showing that as a jump would be wrong.
Where risk comes from
Risk scores are produced when products are calculated, and read from stored results rather than computed while you wait. A product that has not been recalculated since the risk layer was switched on will not have a score yet.
The commodity view in particular needs a recalculation to populate, so if it looks emptier than the rest, that is why.
