Overview of Luxembourg's Closed Subsidy Scheme
The Klimabonus Mobilitéit was funded entirely through the domestic national budget of Luxembourg and administered by the Administration de l'environnement (AEV) under the Ministry of the Environment, Climate and Biodiversity. The programme ran from October 1, 2024, until its final closure in mid-2026, aiming to accelerate the adoption of zero-emission passenger cars (M1).
During its active window, the programme provided a structured tier system. Buyers of new 100% electric passenger cars with an electrical consumption of 16 kWh/100 km or less were eligible for a post-purchase grant of €6,000, capped at 50% of the vehicle's cost excluding VAT. Models with a consumption between 16 and 18 kWh/100 km qualified for a €3,000 tier. Additionally, used electric cars that were at least three years old qualified for a flat-rate grant of €1,500, provided the buyer did not belong to the same household as the seller.
Key Personal Identification and KYC Requirements
To secure the subsidy, individual applicants had to satisfy thorough Know Your Customer (KYC) checks. Natural persons were required to prove their identity and local residency. Applications were submitted using a hybrid process: either digitally through the official MyGuichet.lu platform or offline using paper-based forms.
For digital submissions, applicants verified their identity through recognized national electronic systems, including LuxTrust, Luxembourg's Electronic Identity Card (eID), or eIDAS for cross-border verification. Those who opted for the offline paper-based submission path were required to provide a physical copy of an official identity document. To process the direct bank transfer reimbursement, every applicant had to supply a bank account identification document (RIB).
Required Vehicle and Ownership Documents
Verifying the technical and legal status of the vehicle was a critical step in the application process. The administering authority required a suite of documents to prevent fraud and confirm compliance with environmental standards:
First, applicants had to upload a copy of the official registration certificate, confirming that the vehicle was registered in Luxembourg. Second, a Certificate of Conformity (COC) was required to verify the technical details, specifically the electric consumption rates that dictated whether the vehicle qualified for the €6,000 or the €3,000 tier.
Third, the applicant had to provide a copy of the purchase, rental, or leasing contract identifying the vehicle. To ensure long-term domestic ownership, new vehicles were subject to a 36-month minimum holding period, while used vehicles carried a 24-month minimum holding requirement. If the registered keeper applying for the grant was not the legal owner, they were required to submit a formal declaration of renunciation signed by the vehicle owner.
Documentation for Household and Special Bonuses
The programme featured specialized pathways for large families. For instance, families with five or more members who purchased a seven-seater electric car could qualify for the maximum €6,000 grant, even if the vehicle's electricity consumption exceeded the standard 16 kWh/100 km threshold. To claim this exception, applicants were required to submit an official declaration of household composition to verify their eligibility under the family-size rules.
