1. Nutritional Values (70%)
This is based on the Nutri-Score (link), a scale designed by the French National Health and Nutrition Program. This calculation method takes into account the amount and concentration of calories, fats, sugars, proteins, salts, and fibers. The Nutri-Score has been officially recommended by health authorities in France, Germany, Belgium, Netherlands, Luxembourg and Spain.

2. Quality of Ingredients (30%)
We assess the quality of the ingredients, using the Nova classification score and differentiating whether the food is organic or not. The Nova score is based on the UN food classification system, which divides food products into 4 categories based on their level of industrial processing. Processed and ultra-processed foods are linked to an increased risk of developing numerous diseases (link). In addition, our score emphasises organic foods, which are grown without synthetic chemicals and do not contain genetically modified organisms (link).

We draw on over 2000 scientific studies and internationally recognized databases to assess the carbon emissions of each food product. CO2emissions are calculated for the entire life-cycle of the product: from the farm to your table. 
                  • First, we assign each product to a specific food category, for which we have an estimation of the average CO2 emissions (e.g. Apple, Seafood, Cheddar, etc..). 
                  • Then, we specify what sub-category this product belongs to (e.g. Royal Gala Apple, Mussles, etc.)Soon, we will be able to adjust the CO2 score based on the country of origin, packaging, and production method. We are already providing publicly the most precise and robust estimation of food products’ emissions for free, for the planet.
In addition, we also assess the environmental policies of the brand owner: we base our ratings on the company owning the brand rather than the brand itself. These ratings are based on ethicalconsumer.org analyses and account for 30% of our final CO2 score.

They assess the company’s policies in terms of:

  • environmental reporting
  • climate change
  • pollution
  • habitats & resources
  • palm oil

For example, a negative brand rating reflects that the brand owner has received public criticism in at least one of these areas. The brand rating is available in the app in the detail section of the CO2 score.

Greenhouse gases trap heat and contribute to global warming. Carbon dioxide (CO2) is the most common greenhouse gas produced by human activities, especially from fossil fuels; therefore, it is common practice to represent greenhouse gases with their CO2 equivalent.
It is estimated that 34% of all man-made greenhouse gas emissions are generated by food systems (link). Agricultural activities — crop and livestock— contribute to emissions in many ways:

                  • Fertilizers emit Nitrous Oxide (N2O) from agricultural lands. 1 gram of N2O warms the atmosphere almost 300 times as much as 1 gram of CO2.

                  • Livestock, especially ruminants such as cattle, produce Methane (CH4) as part of their digestive process. 1 gram of CH4 warms the atmosphere almost 25 times as much as 1 gram of CO2.
