Help us make food transparency the norm!

As a non-profit organization, we depend on your donations to continue informing consumers around the world about what they eat.

The food revolution starts with you!


Eco-Score: the environmental impact of food products


The Eco-Score is an environmental score (ecoscore) from A to E which makes it easy to compare the impact of food products on the environment.

Why an environmental score?

More and more consumers are concerned about the impact of their food not only on their health, but also on the health of our planet. Thanks to the Nutri-Score, it is now very easy to take into account the nutritional quality of products when purchasing, but it is very difficult if not impossible to compare their environmental footprint.

It is urgent to provide consumers with clear information about this environmental footprint, so that they can easily and quickly compare it for several products. This is what the Eco-Score environmental grade allows.

The Eco-Score, a tool for more sustainable food

The Eco-Score helps consumers who wish to move towards a more sustainable diet, by encouraging them to:

  • Eat less meat but of better quality
  • Consume more organic products and products with quality labels
  • Favor local and seasonal products, with little packaging
  • Limit products containing problematic ingredients (endangered fish, unsustainable palm oil)

What is the Eco-Score?

The Eco-Score is designed on a model similar to the Nutri-Score: it is a grade from A to E which summarizes 15 environmental impacts. The Eco-Score score is materialized by a colored leaf-shaped logo with a letter from A (very low impact) to E (very high impact).

How is the Eco-Score calculated?

The benchmark score: life cycle analysis (LCA) with data from the Agribalyse database

For each product category, a benchmark score is established using data from the Agribalyse environmental database designed by ADEME and INRAE. These data correspond to the life cycle analysis (LCA) of the products.

Life cycle assessment (LCA)

Life cycle analysis is a standardized assessment method for carrying out a multi-stage environmental assessment and multi-criteria:

  • 6 production steps: agriculture, processing, packaging, transportation, distribution and consumption
  • 14 environmental impact indicators: climate change/carbon footprint, ozone layer depletion, ionizing radiation, land, water, and energy use; pollution of air and marine and fresh water (particles, acidification, eutrophication); and depletion of resources.

Bonuses and penalties to refine the grading of each product

In order to take into account certain impacts on the environment which are not covered well by the life cycle analysis (such as biodiversity) and the specificities of each product within the same category, the score of reference is modulated with bonuses and penalties:

Mode of production

A bonus is awarded to products that have an official label, a label or a certification that guarantees environmental benefits (organic, fair trade, HVE, Label Rouge, Bleu Blanc Cœur, MSC/ASC).

Poreklo sastojaka

A bonus is awarded based on the origin of the ingredients. This bonus takes into account the impact on transportation and also the environmental policy of each producer's country.

Endangered species

A penalty is given to products that contain ingredients that have significant negative impacts on biodiversity and ecosystems, such as palm oil, the production of which is responsible for massive deforestation.


A penalty is calculated to take into account the circularity of packaging (use of recycled raw material and recyclability) and overpacking.

An increased need for transparency to better measure and reduce environmental impacts

To accurately calculate the Eco-Score, it is necessary to have information which is not necessarily specified on the packaging (such as the origin and the exact percentage of each ingredient) or which is rarely available in usable form (such as a list of all the components of the packaging with the precise types of plastics used).

Average values are used when this information is not yet available, but we are now calling on everyone to help us collect this information which will be very useful for the Eco-Score but also for many other uses.

How to see the Eco-Score for food products?

Scan products with the Open Food Facts app

The Open Food Facts app allows you to quickly get the Eco-Score of products: all you have to do is scan their barcode. If you have already installed the Open Food Facts app, please update it to get the new version!

The Eco-Score on the Open Food Facts app

The Eco-Score is, or will soon be, available in the apps of the launching partners. And Open Food Facts is a Wikipedia of foods that anyone can reuse freely and for free. The more than 100 applications that use the OFF database will also be able to display the calculated Eco-Score.

Compare the Eco-Score of products on the Open Food Facts site

The Open Food Facts website allows everyone to see and compare the Eco-Score of more than 750,000 food products sold in France. The results of each search show the nutritional quality with the Nutri-Score, ultra-processed foods with NOVA, and the environmental impact with the Eco-Score. The Eco-Score will be rolled out to other countries as soon as an applicable Eco-Score calculation is available.

Obtain the details of the Eco-Score calculation for all products

For each product, a link allows you to display the complete details of the Eco-Score score calculation.

And if information is missing, anyone can add it: the manufacturer of the product but also all citizens committed to the climate, environmental protection and transparency.

How the Eco-Score can encourage the improvement of products and the reduction of their environmental impacts

The Eco-Score has two levers of action:

  • With the Eco-Score, consumers can make a more informed choice by taking into account the environmental impact of products as a criterion of choice.
  • The Eco-Score also encourages manufacturers to improve their products so that they achieve a higher Eco-Score rating.

Manufacturers improving the Eco-Score of their products is the ultimate goal, as it will benefit all consumers.

The energy rating of household appliances has thus profoundly transformed the market (try to find a fridge rated E, or even D or C!). And the democratization of Nutri-Score has also encouraged many manufacturers to improve the nutritional quality of their products to obtain a better rating (to the point that some French manufacturers even brag about it on bus stops, such as Brossard for its Savane cake).

To encourage product improvements, our platform for producers automatically analyzes data provided by manufacturers to identify avenues for improvement. The platform thus identifies all the products that would obtain a better Nutri-Score score with a slight change in composition (a reduction in salt of 5% for example).

Soon, the platform will make it possible to suggest ways to reduce the ecological impact and obtain a better Eco-Score (for example by using a more recyclable plastic for packaging, or by replacing palm oil with another oil).

How can we find out more and how can we help us develop the Eco-Score?

Everyone is welcome to help us create more transparency, educate consumers, and encourage product improvement through Eco-Score.

The Eco-Score is still young and can certainly be improved. Given the climate and environmental emergency, however, it seems important to us to make it available now.

By working together, we will be able to gradually improve the Eco-Score, refine its formula, and gather the data necessary for its calculation.

Your feedback, observations and suggestions will therefore be very valuable.

Open Food Facts is a collaborative project supported by tens of thousands of volunteers and managed by a non-profit association with 3 employees.
You can help us at fund Open Food Facts 2023 budget and continue to develop the Eco-Score and many other projects to improve everyone's diet. Thank you! ❤️
