Calculation of the carbon emissions of your banking transactions.

Issues are estimated by applying a "monetary issue factor" to each expenditure based on the product, service or basket. This factor corresponds to the ratio of a product's emissions to its price. It can also be calculated from the ratio of a business sector's emissions to its turnover.

By product

when the price indicates the quantity (e.g. in transport with petrol, or housing with electricity)

By department

by applying to the price the ratio of the company's carbon balance sheet to its turnover (e.g. insurance contract, computer licence, bank charges, etc.).

By average baskets

composed of typical products with a known average carbon footprint and price (e.g. food, clothing, etc.) according to the monetary factors method detailed by ADEME.

Greenhouse gas (GHG) emissions from your purchases

The Euro/Carbon conversion coefficients of your purchases are calculated according to three methods.

GHG by product

When it is possible to deduct the quantity of a product from its quantity, for example in transport with petrol, or for housing with electricity;

For example, the emission factors for electricity in France are 0.32 kg of CO2eq per euro spent. This figure is obtained by estimating the average emissions of a conventional electricity contract in France, which are 0.0571 kg CO2eq/kWh, with an uncertainty of 5%, and the regulated tariff in 2019 was 0.1765€ including tax per kWh of electricity in 2019.

GHG per service

By applying to the amount of the expenditure a coefficient per sector of activity or per specific company ratio. This method is particularly well suited to services, especially IT and financial services, or cultural offerings. This ratio is calculated by dividing the carbon footprint of the company or sector (scope 1,2,3), by its turnover;

For example, the emission factors of video streaming are estimated at 1.44 kg of CO2eq per euro spent. Indeed, video on demand (VOD) would have emitted 102 Mt of CO2eq for a total turnover of 71 billion in 2018.

GHG by baskets

When a banking transaction refers to grouped purchases of products, for example in food or clothing. According to a method used by ADEME, the estimate is obtained from a representative mix of typical products, whose carbon footprint and average prices are known. For this category, Greenly aims to continuously refine the analyses, and to allow users to specify which item it is, in order to make the estimates even more precise.

They're beating the odds at Greenly

Our daily battle is simple: to accelerate the development of the technology of our various offers to enable each player, whether companies, banks or private individuals, to better monitor and control their CO2 emissions.

We are convinced that behavioural change is the most effective way to fight global warming.

Digital technology makes it possible to measure invisible things, and to invent new economic models that finance prevention, creating immediate incentives for more virtuous behaviour. We are convinced that changing behaviour is the most effective way to fight global warming, and that a simple measure must be generated on a daily basis to value good behaviour.
