The Greenly Carbon Index

Greenly's Carbon Index is continuously improving, thanks to its data scientists and the active support of a community of engaged users. As they use the app, suppliers relabelling and user preferences feed into a self-learning model that keeps providing more accurate estimations of the footprint of every expense and product. This lets you make better choices for the planet on a day to day basis.

How Greenly enriches every banking transaction to estimate your carbon footprint

Emissions are estimated by applying a "monetary emission factor" to every expense, based on supplier labelling, scoring, and identification of underlying products, services or carts. Input of  preferences allow users to fine-tune these ratios and improve the model. Emissions factor are typically obtained by computing the ratio of a product or a services over its price. They can also be obtained using the ratio of a company's total footprint over its total revenues. This lets Greenly score companies against each other to offer more precise recommandations.

By product

When your expense reflects the quantity of a product, (e.g. gas, water or electricity), Greenly multiplies the amount by the footprint of the product for a given unit of the currenly

By service

When you pay for service, Greenly multiplies the amount paid by the ratio of the company's carbon footprint over its turnover (e.g. insurance contract, computer licence, bank charges, Netflix etc.).

By average carts

When purchase groups several items, ratios reflect average carts with typical footprint and  price (e.g. food, clothing...). Ratios are fine-tuned with in-app user preference or product relabelling (e.g., food regimen)

Measure your Greenhouse Gas (GHG) Emissions

Currency / carbon conversion factors of your every expenses are calculated along three methods:

When it is possible to deduct the quantity of a product from its quantity, for example in transportation with gasoline, 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.Translated with www.DeepL.com/Translator (free version)


By applying a coefficient to the amount of the expense by sector of activity or by 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 revenue.

For example, the emission factors for 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.Translated with www.DeepL.com/Translator (free version)

When a banking transaction refers to group purchases, for example in food or clothing. According to a method promoted by the GHG protocol, estimations are obtained from a representative mix of typical products, whose carbon footprint and average prices are known. For this category, Greenly's objective is to continuously refine the analyses, and to allow users to specify which item it is, in order to further refine the estimates.

It was high time we put artificial intelligence at the service of the fight against global warming, that is, in more accurate terms, a self-learning technology that constantly refines the measurement of our ecological impact, and helps everyone make better choices on a daily basis thanks to contextualized recommendations.
