Sustainable and inclusive development booklet (LDDS)

Verified 01 August 2023 - Legal and Administrative Information Directorate (Prime Minister)

The booklet of sustainable and solidarity development (former Codevi) is a paid savings product whose funds are available at all times. All banking institutions can offer it.


Any adult who has his tax domicile in France can open a booklet of sustainable and solidarity development (LDDS).

The number of LDDS is limited to one per person (or up to 2 booklets per tax household).


A minor who is resident in France for tax purposes can open a booklet for sustainable development and solidarity, if he has personal income and is no longer attached to his parents' tax home.

There is no minimum amount in the act.

However, most institutions require a down payment of €15.

Withdrawals and payments are free.

The bank can give you a debit card, but you can only use it at the ATMs on its network.

The operations carried out on the LDDS are free of charge: opening, deposit, withdrawal and closing.

You can contribute to your sustainable development and solidarity booklet by check, cash at the counter or by transfer from a demand account.

As of July 1, 2023, you can make a transfer to your LDDS from a bank account opened at a different bank than the one where the LDDS is located.

The LDDS ceiling is €12,000.

This means that the total amount you deposit into the account must not exceed that amount.

But the cap can be exceeded when interest is added to your savings.


The annual interest rate is 3%.

Calculation of interest

Interest is calculated on 1er and the 16th of each month.

The date of the value, taken into account for the calculation of interest, varies according to the date of the transaction (deposit or withdrawal):

Last day of previous month

15 of the month

The sums deposited bear interest if they are invested in whole fortnight.

On December 31 of each year, the interest accrued on the year is added to the capital. The addition of interest on December 31 may increase the value of the booklet beyond €12,000.

You can use the money saved on your LDDS to make a donation to a social and solidarity economy company.

The bank with which you have your booklet must offer you each year a list of at least 10 companies of the social and solidarity economy.

Once you have communicated the names of the selected companies and the amount of the donations, the bank can make the payment directly from your LDDS.

Banks must use the funds collected under the LDDS to grant loans to improve the energy performance of housing at attractive rates.

What work is eligible?

This involves energy-saving work carried out in individual or collective dwellings that are used as main or secondary dwellings, or that are rented out.

Example :

Thermal insulation materials, temperature control apparatus, power generation apparatus

It is the banks that check the eligibility of the works based on the quotes.


You don't need an LDDS to qualify for the Sustainable Development Loan.

This loan can be granted to individuals, condominiums and construction professionals to carry out certain work.

Amount, rate and duration of the loan

The banks are free to set the amount and duration of the loan, depending on the nature of the work and the creditworthiness of the borrower.

They have an obligation to offer attractive rates, but there are no government-imposed rates.

The conditions for granting the loan may therefore vary from one bank to another.

Interest shall be exempt from income tax and social security contributions.

To close your LDDS, by simple letter or by traveling to your bank, you must specify the following information:

  • LDDS References
  • Account number where the amounts remaining on the booklet are to be deposited

If the LDDS is closed during the year, interest on the period since the beginning of the year is credited to the closing day.
