GreenScore® System Method

How do we rate food & beverage products?

Our GreenScore® System uses an unbiased, evidence-based approach to evaluate food and beverage products’ impact on your health and the environment. We score products across four categories: nutrition, processing, food safety, and environmental footprint. 

 

Within each category, products are scored from 1 to 100. A product’s total GreenScore® is the average of its four category scores, with each category weighted equally. 

 

When we suggest products to you, we use your GreenScore® category weights to identify products that match your values particularly well.

1. Nutritional Value

For the Nutrition Score, each product is evaluated based on (i) the key ‘beneficial nutrients’ it supplies, (ii) the amount of ‘nutrients to limit’ it contains, and (iii) whether it provides healthful foods such as fruits, vegetables, nuts, seeds, and legumes. The more nutritious a product is, the higher it will score.

70 - 100

60 - 69

50 - 59

0 - 49

Very high nutritional value

High nutritional value

Some nutritional value

Low nutritional value

2. Level of Processing

For the Processing Score, each product is evaluated based on the degree of processing it has undergone, specifically (i) the processing methods used and (ii) whether it contains natural or artificial sweeteners, flavors, colors, or other additives. The closer a product is to its natural state, the higher it will score.

90 - 100

50 - 89

0 - 49

Unprocessed or minimally processed

Moderately processed

Highly processed

3. Food Safety

For the Food Safety Score, each product is evaluated based on (i) the risk associated with pesticide and herbicide residues from production (considering probability and toxicity), (ii) the use of antibiotics and hormones (when raising animals), and (iii) the presence of toxic additives (with known health concerns). The lower the risk, use and presence, the higher it will score.

100

75 - 99

50 - 74

25 - 49

No health risk

Low health risk

Moderate health risk

Significant health risk

0 - 24

Very significant health risk

4. Environmental Footprint

For the Environment Score, each product is evaluated based on its (i) estimated carbon footprint and (ii) estimated water footprint, per serving. The carbon footprint considers the greenhouse gas emissions (measured as carbon dioxide equivalents) emitted throughout the lifecycle of each ingredient. The water footprint considers the blue, green, and grey water used throughout the lifecycle of each ingredient. The lower the estimated footprints, the higher a product will score.

95 - 100

90 - 94

Very low footprint

Low footprint

65 - 89

30 - 64

6 - 29

0 - 5

Moderate footprint

High footprint

Very high footprint

Extremely high footprint
