Director of Client Commitment at BNP Paribas
"We are very pleased to have formed a partnership with one of our finest impact startups. We have been seduced by Greenly's participative and transparent approach, which allows us to help our customers to estimate their emissions ever more accurately. This approach is in line with our desire to commit ourselves more to more sustainable development, based on concrete tools that are immediately available to our clients".

BNP Paribas

To help you estimate your carbon footprint, BNP Paribas has teamed up with Greenly, a French startup specialising in carbon footprint calculations. The aim? To offer you simple, concrete and fun ways to become aware of your impact on the environment and to give you the keys to reducing your CO2 emissions.

Our approach is pedagogical and evolutionary. It is only a first step.

Becoming aware of its impact is a key phase for success. This is why we have developed for our customers, together with our partner Greenlyan estimator of the CO2 impact of daily expenses. In addition to managing their budget from their app, our customers can also BNP Paribas and Hello bank! can now also monitor the carbon impact of their spending and find ways to reduce it.

Functionality directly in your BNP and Hello Bank banking services

The My Carbon Footprint feature is accessible from the My Accounts application. Log in to the application and find the My Carbon Footprint feature in the menu.

If the feature does not appear, update the My Accounts application from the Play Store on Android or the Apple Store on IOS.
To use the My Carbon Footprint feature you must have activated the categorisation of your transactions. If it is deactivated, activate it from your Client Area on the website.

Your questions about the My Carbon Footprint tool

Carbon Footprint, why is it important to reduce it?

Without a reduction in greenhouse gas (GHG) emissions resulting from human activity, the average global surface temperature would rise by 2°C to 3.5°C by 2100, according to IPCC (Intergovernmental Panel on Climate Change) projections. This global warming points to an increase in the number of extreme weather events, particularly droughts, rising oceans and their acidification, with many negative consequences on health and human development.
In 2016, the countries that signed the Paris Agreement agreed to limit their CO2 emissions to keep warming below 2°C. They have committed to reducing the share of fossil fuels in production, and have set an emissions target of around 2 tonnes of CO2 per year per inhabitant. In 2018, the average carbon footprint of a French person was 11.2 t of CO2eq per year. In addition to structural efforts to change our production methods and have a positive impact on the environment, the commitment of individuals to a decarbonation of their consumption and lifestyle is essential to achieve these reduction targets.

How is my carbon footprint estimated?

Your carbon footprint is estimated by calculating the associated greenhouse gas (GHG) emissions for each of your expenses (bank transactions debited from your deposit account). The wording of the transaction makes it possible to categorize the expense and thus determine the type of shopping cart, product or service associated with it. A coefficient, specific to each purchase category or supplier, is applied to the amount of the expenditure. These coefficients, called "monetary emission factors", are used to convert euros into kg of CO2. Provided by the Greenly Participatory Carbon Standard, they correspond to the ratio of a product or service's emissions to its price. They can also be calculated as the ratio of a sector's emissions to its turnover.
The estimate of your carbon footprint is accurate for expenses that concern sectors whose products are homogeneous in terms of carbon intensity. In particular:
- transport (petrol),
- housing (electricity, gas, water, etc.),
- everyday services (Internet, telephone subscription),
- shopping baskets made up of products of the same nature.

Conversely, the estimate is less accurate for business sectors where banking transactions involve purchases of heterogeneous product categories, such as food (meat and/or vegetables) or transport (airplanes, trains, etc.). BNP Paribas is working to improve the way in which individual behaviour is taken into account and to refine these categories to enable you to estimate your carbon footprint more accurately.

How can I refine my carbon footprint estimate?

It is possible to refine the estimate on certain categories of expenses, particularly food and transportation, by analyzing the nature of your expenses more closely.
Your eating habits have an impact on the estimate of your carbon footprint. For example, the carbon footprint of your diet is calculated on an average meal. In order to obtain a more precise estimate, you can multiply the results obtained, using the "My Carbon Footprint" estimator available on your My Accounts application (section...), by one of the following coefficients.
For your supermarket purchases ("Food, supermarket" category):
- Vegetarian diet: 0.39
- Flexitarian diet: 0.79
- Red meat diet: 2.4

For your restaurant expenses ("Restaurants, bars" category):
- Vegetarian diet: 0.13
- Flexitarian diet : 0.26

To refine the estimate of the carbon footprint of your transport expenditure, you can calculate the emissions of your air travel and train travel separately by multiplying the amount of the expenditure by one of the following factors depending on the mode of transport used:
- For a train journey: 0.0331
- For an air journey: 1.695
