To help low-income households change cars, the state will set up a zero-rate loan. This is one of the measures of the climate law, voted definitively in mid-2021.

On April 24, 2022, a decree was published in the Official Journal. This law prohibits the circulation of vehicles that are too old and polluting, even if there are exceptions, in particular for vintage cars. It also facilitates the transition to less polluting vehicles. More specifically, from January 1, 2023, low-income households and micro-enterprises residing or working in certain low-emission zones (ZFE) will be able to benefit from a zero-interest loan for the purchase of an electric or hybrid vehicle.
We are talking here about the experimentation of a zero-interest loan (PTZ) to finance the acquisition of a vehicle with low carbon dioxide emissions within the framework of the application of the Climate and Resilience law of August 22, 2021 , which entered into force on January 1, 2023 for a period of two years.
What amount? What conditions to obtain it?
The loan is for a maximum amount of 30,000 euros and will have to be repaid over a maximum of seven years:
- 30,000 euros in case of purchase;
- 10,000 euros in the event of long-term rental or rental with purchase option (in LOA or LLD).
Only credit institutions and finance companies that have concluded an agreement with the State may grant a PTZ.
The natural persons eligible for the loan are those with a reference tax income per unit less than or equal to 14,000 euros . For legal persons, these are the microenterprises who are concerned.
Where are the ZFE zones?
You must live or work in an intercommunity of which part of the territory is located in a mobility low emission zone (ZFE-m)on January 1, 2023, or in a directly neighboring intermunicipal authority.
Here is the list of cities:
- Paris and metropolis of Greater Paris;
- Grenoble (27 municipalities, including Grenoble);
- Lyons;
- Toulon-Provence-Mediterranean;
- Rouen-Normandy;
- Strasbourg;
- Nice-Cote d’Azur;
- Toulouse;
- Montpellier-Mediterranean;
- Aix-Marseille-Provence.
It is therefore about ten large metropolises and not all metropolitan cities with more than 150,000 inhabitants which will have to create an EPZ by December 31, 2024, under the Climate and Resilience law.
Which cars are eligible?
The interest-free loan will be intended to finance the acquisition, or the long-term rental or with an option to buy for at least two years, of a passenger car or a van whose total authorized laden weight is less than or equal to 2.6 tons and whose carbon dioxide emissions are less than or equal to 50 grams per kilometer.
We are talking about vehicles 100% electric or plug-in hybrid. Another constraint: the purchase price including VAT of the vehicle, before deduction of aid granted by the State and local authorities, must not exceed 45,000 euros for a private car or 60,000 euros for a van. We should add that this amount allows you to benefit from an ecological bonus.
