Your carbon footprint is related to your lifestyle. Yayzy developed an innovative algorithm that uses your bank account transactions to calculate your carbon footprint. To calculate your monthly carbon footprint, we estimate the emissions of each of your transactions and we sum it all together.
The carbon footprint of each transaction results from multiplying the amount spent of each payment transaction times the corresponding greenhouse gas (GHG) emissions intensity factor on a product, company or sub-category level.
Money spent * GHG emission intensity factor = Carbon Footprint
Yayzy Carbon Footprint Algo © sources Green House Gas intensity factors from multiple renown sustainability data providers such as,
Vitalmetrics,
UK Government Guidelines for Carbon Footprint reporting, and
United Nations International Civil Aviation Organization (ICAO).

IF YOU ARE BRAVE, KEEP ON READING!
Yayzy developed the most advanced algorithm to calculate an individual’s carbon footprint. Yayzy carbon footprint algo © uses data science to identify the sources of greenhouse gases emissions (GHG) within your payments data and match them against the best greenhouse gas intensity factor to get the most accurate and bespoke estimation of your personal carbon footprint.
In order to compute the most accurate carbon footprint estimation, the Yayzy carbon footpring algo © matches payment information on a product, retailer or subcategory level against the appropriate greenhouse gas intensity factor. The more granular the data, the more accurate the estimation.
Money spent (£) * GHG emission intensity factor (kg of CO2e / £) = Carbon Footprint (kg of CO2e)
The Yayzy carbon footpring algo © gets payments data from
TrueLayer, an FCA regulated firm that provides an API to access data from your bank accounts and cards. Moreover, it gets itemized transaction information directly from retailers (with your consent), and direct integrations to lifestyle apps such as Uber, Ryanair, London Underground among others. Yayzy keeps integrating sources of payments data to increase the accuracy of the carbon footprint estimation. Yayzy carbon footprint algo © sources Green House Gas intensity factors from Vitalmetrics, greatly renown sustainability data provider,
UK Government Guidelines for Carbon Footprint reporting, and
United Nations International Civil Aviation Organization (ICAO).
The greenhouse gas (GHG) intensity factors are sourced mainly from VitalMetrics’ Comprehensive Environmental Data Archive (CEDA), a suite of environmental input-output (IO) databases that are designed to assist various environmental systems analyses, including life cycle assessments (LCA), carbon footprinting, water footprinting, and sustainable spend analyses. CEDA quantifies products’ natural resources use and environmental emissions throughout their life cycles by connecting input-output tables, which represent the entire supply-chain network of an economy.
For specific use cases we get additional user inputs to increase the accuracy of the carbon footprint estimation. As an example, in order to increase the accuracy of air travel, you can input departure airport, arrival airport, and cabin class, then the Yayzy carbon footprint algo © will compute the carbon footprint using fuel consumption by aircraft type for your specific journey.
Yayzy follows best-in-class carbon footprint methodologies that are followed by publicly listed corporations and tailors it for you. In case you would like to learn more or contribute knowledge, please reach out to
