Here’s how we calculated

The following calculation is based on milk (white milk) only. The corresponding oat drink product are enriched Oat Drink (fresh and long-life). We have NOT included other dairy products such as yoghurt, cheese, ice cream and cream.

We have calculated the quantity of saved CO2e in kg. (Not water resources, land use etc.). These numbers are based on the average milk consumption per person per year (85.9 litres per person per year, according to the Swedish Board of Agriculture, Swedish Milk Consumption 2011) and use the figure (quantity kg carbon dioxide equivalents) that we obtained from the Life cycle analysis (LCA)* previously carried out.

This following equation applies to all private individuals who sign up.

Emission per L milk: 1.3 kg CO2e
Emission per L Oat Drink (average aseptic and fresh): 0.45 kg CO2e
Difference: 0.85 kg CO2e
Result: A savings 0.85 kg CO2e per L milk if you change to oat drink.

A Swedish person drinks an average of 0.235342466 L milk/day X 3 days X quantity saved kg CO2e per litre (0.85 kg CO2e/L) = 0.600123288 kg CO2e per person per three days.

When someone signs up, the figure of 0.600123288 kg CO2e is automatically displayed by the ticker!

Companies will have to estimate the number of L consumed in their business over a three day period. We multiply the quantity in L, e.g. 100 L, by the figure (saved CO2e per L) 0.85 kg CO2e = 85 kg CO2e.

Note: All calculations have been made according to the replacement of milk with oat drink and NOT simply refraining from drinking milk. After all, people will still be thirsty.
