Klimetra’s figures are estimates built from recognised public food databases. Danish and European data always come first.
Where the data comes from
| Data | Source | Licence |
|---|---|---|
| Estimated CO₂e | CONCITO (2024): Den Store Klimadatabase, version 1.2 | CC BY, adapted by Klimetra |
| Estimated CO₂e where Danish data is missing | ADEME: AGRIBALYSE 3.2 | Licence Ouverte (Etalab) |
| Nutrition | DTU Fødevareinstituttet: Frida food database | Terms of use to be confirmed |
| Nutrition where Frida has no value | USDA: FoodData Central | Public domain (CC0) |
How Klimetra calculates
Estimated CO₂e. Each ingredient has an emission factor in kg CO₂e per kg. Klimetra multiplies the quantity of each ingredient by its factor and adds them up for the whole recipe. The result is shown per 100 g and per serving. The factors are average values per food type: the actual emissions of a specific product vary by producer, origin and season.
Nutrition. Energy, protein, fat and carbohydrates are calculated the same way, from average values per 100 g. They are calculated, not measured in a laboratory.
Allergens. Klimetra suggests the 14 EU allergens from the ingredients in a recipe. Where the data is uncertain, an allergen counts as present. A recipe contains an allergen if any of its ingredients does. Cross-contact in the kitchen and the specific products you buy are not covered.
Diets. Klimetra suggests whether a recipe suits five diets: vegan, vegetarian, ovo-vegetarian, pescetarian and lactose free. A recipe suits a diet only if every ingredient does.
You decide. The allergens and diets are suggestions. You review them, can change any of them, and confirm each recipe before its materials can be downloaded. Your final choice is what appears on your materials.
Same recipe, same result
Every calculation uses fixed formulas and fixed data. No AI is involved when a recipe is calculated. Values only change when you edit the recipe, or when a source publishes a new version and Klimetra updates its data.
Unknown is never zero
If a value is missing for an ingredient, Klimetra shows “–” instead of a number, and marks the recipe’s total as incomplete.
