The uniqueness of Contovista’s solution, developed in collaboration with our partner Deedster, lies in its reliance on real transaction data directly from the customer’s bank account. Through this approach, we achieve a comprehensive and accurate calculation of the individual’s CO₂ consumption, providing near-real-time insights.
The carbon footprint calculation is based on two key factors:
- Transaction data categorisation by Contovista
- Sustainability information sourced from our partner, Deedster
The highly granular categorisation of transactions is made possible by Contovista’s data-driven banking expertise and digital linking with CO₂ data from the GreenTech Deedster.
Transaction data is broken down by categories and subcategories (approx. 240 subcategories). The multibanking option also allows data from accounts at other banks to be included.
For this purpose, Deedster uses high-quality, research-based Swiss climate data (CO₂ equivalent values, CO₂e), expressed in kilograms of CO₂e per Swiss franc, aligned with the national pricing landscape. The climate data comes from Deedster’s partnerships with Exiobase, WWF, Exponential Roadmap Initiative, and Race to Zero (UN), among others. We achieve a very high level of accuracy in calculations thanks to these multiple data sources. Nevertheless, there are still certain inaccuracies due to actual purchasing behaviour in individual cases.
