Based on vendor category and spent amount we calculate the carbon footprint of every payment with your Tomorrow card.
Relatable comparisons and monthly insights help you understand your CO₂ footprint and make good choices. You’ll see which emissions you might be able to reduce or compensate for.
Stream netflix or better buy a new book? Order vegan food or make ramen yourself?
Every single day you face more than 20,000 choices. Many of them have an impact. We don’t want you to miss out on everything that’s fun. But every tiny behavioral change can have a positive impact and motivate others to do the same.
The CO₂ values are calculated by our partner Ecolytiq, a data company located in Berlin.
The basis for the calculation is publicly available data, studies and research projects (e.g. from the Federal Statistical Office) on individual areas of life. From this, Ecolytiq developed a formula that can analyse and calculate the CO₂ value for each purchase in real time.
Based on the categories assigned to the merchants and the purchase price paid, we calculate the CO₂ emissions of your purchase for each payment you make with the Tomorrow Card.
In the category "food", we already ask you for additional (optional) feedback that provides further details about the purchase (e.g. vegan, vegetarian, flexitarian, etc.). This enables a more precise calculation. In the future, we plan to expand this option to other categories as well.
Ecolytiq uses a merchant code (MCC) provided by Visa as the basis for the calculation, plus the mentioned feedback loop for refining the calculation. This way user behaviour can be taken into account better.
The calculation of the CO₂ emissions is based on average values that Ecolytiq collects from publicly available data, studies and research projects on the individual areas of life (e.g. from the Federal Statistical Office).
Of course, we do not know the exact content of your groceries, hence it cannot be taken into account for the calculation. The values represent an average and an approximation, that becomes more accurate in the sum of many transactions.
So there is no distinction yet in the CO₂ footprint, whether you bought minced meat or organic vegetables in the supermarket. However, you can refine your CO₂ footprint for food transactions by feeding the feedback loop with more information about your diet (do you eat vegan, vegetarian, mixed?).
In the future, this fine-tuning will be extended to other categories (e.g. traffic/transport). For starters, it is similar when it comes to differentiating between retailers: whether you buy various t-shirts for 20€ at a discounter or a fair-trade organic t-shirt from Armed Angels for 100€, cannot yet be calculated to the benefit of more sustainable shopping. Also the supermarket itself (discounter or organic shop around the corner) is not differentiated yet.
The background is the following: The merchants are recognised and assigned by VISA on the basis of the transmitted codes. Here, for example, the discounter and the organic supermarket are grouped together in the same category. Of course, we are working on making your emissions even more personalised and precise.
Nevertheless, the Footprinting feature is a great start to develop more awareness about the areas of your life that may be hiding CO₂ guzzlers of which you were previously unaware. Or even, what doesn't matter as much as you first thought. Just give it a try!
Ecoyltiq receives the user data from us pseudonymised and creates user profiles on this basis. We have full control over the data that goes to Ecolytiq.
Once you switch off the feature, your data used until then will be deleted by us and by Ecolytiq, and no further data will be collected for the CO₂ footprint feature.
Also good to know: We cannot see what you have bought, the calculation of the CO₂ emissions is based solely on the price paid and the retailer involved.
