The environmental score: Transparency in terms of sustainability

Eat more environmentally conscious in the dining halls of the SW KA

The meal plan of the Studierendenwerk Karlsruhe contains the environmental score bases on the Eaternity database (EDB) and indicates with a star rating how climate-friendly the food is. The Eaternity Score is the first award for a future with climate-friendly food worldwide and is calculated together with scientific partners.

You can read the 3-star rating here.

Legend for the environmental score

The score shows the climate impact in four areas. First of all, an average score is calculated and displayed for each meal in the menu. This is calculated from the evaluations of the four areas of climate, water, animal welfare and rainforest, the evaluation of which can be seen in the detailed overview.


The detailed areas are rated with 0-3 stars. You can see this information on our meal plans for each meal.

Climate:
Stars are awarded depending on the amount of CO₂ emissions in grams. In the case of particularly low consumption (3 stars), the "climate plate" is also awarded.

Important: We evaluate the meals / products regardless of the portion size. This means that even if a portion is smaller, this does not automatically mean that the CO₂ emissions are lower.

Water:
Depending on the consumption in liters, 0-3 stars are awarded. Particularly low consumption is marked with 3 stars.

Animal welfare:
3 stars:  vegan/properly reared
2 stars:  partially certified
1 star:    No certification

Rainforest:
3 stars:  protected
2 stars:  partially protected
1 star:  not protected

Note: We already calculated the environmental score for most of our meals and this is shown accordingly. However, it is constantly being updated and expanded.

Calculation of the average score

Here are two examples of how to calculate the average environmental score according to the 3-star rating system.

Auf- und Abrunden des durchschnittlichen Umwelt-Score:

> 0,5 = round up
< 0,49 = round down

Examples:
0,25 = round down to 0 stars
1,25 = round down to 1 star
1,5 = round up to 2 stars
1,75 = round up to 2 stars

What ist the climate plate?

The climate plate is a National Climate Protection Initiative project funded by the Federal Environment Ministry and its partner NAHhaft. A climate-friendly meal is awarded the climate plate if it causes at least 50% less CO2 than a comparable, average meal (3 stars). Students, employees and guests have the opportunity to choose their food according to the aspect of climate friendliness and to be made aware of the connection between climate change and nutrition. You will be motivated to eat (more) climate-friendly in the dining hall and also to cook more climate-friendly in your private life.

The overarching goal is to reduce the emissions of the nutrition sector in the area of communal catering by NAHhaft supporting and accompanying the Studierendenwerke (STW) throughout Germany in making their food offer more climate-friendly.

Where does the data come from?

Details on the Eaternity Database (EDB)

The EDB contains CO₂eq. values and standard processes for all common foods on the basis of seasonality, cultivation methods, transport, preservation and processing models. The developed greenhouse model determines the CO₂eq emissions related to the heating of greenhouses in both, organic and traditional farming. The individual food CO₂eq values are the result of our collaboration with scientists from ZHAW – Zurich University of Applied Sciences and Quantis – World Food Database, University of Zürich (UZH), Swiss Federal Institute of Technology in Zurich (ETHZ), Research Institute of Organic Agriculture (FiBL), ecoinvent v3.6, Agribalyse, Agri-footprint, peer-reviewed literature, reports (grey literature), extrapolated; or they are based on our own research subsequently adjusted to assure comparability. The EDB is currently the largest and most comprehensive database to carry out CO₂eq calculations for food produce worldwide. The EDB also contains the Eaternity Health and Organic performance. It comprises of nutritional values, water scarcity footprint, and our Health Score for the assessment of the health risk factors of your food consumption.
