Eaternity has a special way to give ratings for the CO₂ values provided on ingredients, recipes and reports. The biggest benefit is that every portion, no matter how big or small it is, can now be awarded being climate-friendly.

This has important implications, as we can give a climate-friendly award for buffets, side-dishes or even snacks and food products. This means, we can apply what we are doing to many businesses. Also the overall restaurant comparison is fair.

Rating Explanation

A: very good (dark green / 3 stars) : Eating only these foods, would reduce our carbon footprint at least by ½ (the goal we need to reach by 2050)
B: good (light green / 2 stars) : These foods are better than average. Each of those will reduce your carbon footprint.
C: not good (red / 1 star) : These foods are worse than average. Each of those will increase your carbon footprint.
D: These are the worse than double the average.: Avoiding those foods should be your second priority.
E: These are worse than four times the average.: Avoiding those foods should be your first priority.

<aside> ℹ️ Previously we normalized by weight or by kcal. This lead to various issues. Normalizing by weight meant, that the best foods were those with a lot of water. Normalizing by kcal led to the fattiest foods having the best score. We agree that both dimension carry meaning, as we need to "fill and fuel" our body. Yet we need to take both into consideration to the respect they fill a requirement for the human body.

How does it work?

We create a unit (DFU) respective to the daily requirement of a person to normalize all food items. This DFU is orthogonal (independent) to our Climate Score, Water Footprint and our Health Score. Which means it cannot have any of their metrics included that indicate healthy foods (like: fiber, high trans fatty acids, low polyunsaturated fatty acids, sodium, etc.). It serves as a proper normalization function.

We include the following nutrients, respective to their recommended daily amounts (as given by the German Health Society (DGE) and other commonly used standards, like the Nutrient Rich Food (NRF) index):

g proteins / 50 g
g fats / 66 g
kJ (the rest of it) / 6000 kJ
g water / 2500 g
