Other services of ACALuxembourg Green Card Bureau and Motor Guarantee Fund
The Luxembourg Green Card Bureau and Motor Guarantee Fund bring together all Motor Civil Liability insurers that are authorised to operate in this sector in the Grand Duchy of Luxembourg.
The Luxembourg Bureau manages claims arising in Luxembourg involving vehicles registered abroad and provides compensatation for personal injury and material damage in accordance with Luxembourg law.
The mission of the Motor Guarantee Fund is to compensate personal injury and material damage caused in Luxembourg by a vehicle that is uninsured, unidentified (personal injury only) or, for which, the Motor Civil Liability insurer has become insolvent. It bears the cost of compensation of victims if, within a period of 3 months from the date of presentation of a claim, the insurer concerned has not presented a reasoned response to the cited elements. The Motor Guarantee Fund shall compensate an injured person who is resident in the Grand Duchy of Luxembourg and has been the victim of an accident abroad caused by an uninsured vehicle, as well as so-called «vulnerable» victims.
Insurance Ombudsman
Since 1995, ACA and ULC (Luxembourg Union of Consumers) have offered a joint mediation service as an out-of-court alternative for insurance disputes and to avoid, as far as possible, lengthy and costly procedures.
The Ombudsman has as mission to process applications for out-of-court settlement of insurance litigation between Luxembourg-based insurance companies and consumers residing in Luxembourg or in another State of the European Union. The mediator’s opinions, proposed solutions or agreements are non-binding on the parties concerned.
ABBL, ACA & ALFI EU Representative Office
At the beginning of 2022, the ABBL and ACA agreed to enhance their collaboration on multiple fronts. In order to further leverage existing synergies, ACA is joining the existing representation office of ABBL and ALFI in Brussels, which is now expanding its scope to include insurance and reinsurance matters at the EU level.
The ambition of our association is to broaden the advocacy work of the insurance sector to reach policymakers in European institutions, in addition to other national associations and companies in the industry permanently based in Brussels.
Antoine Kremer set up and heads the representative office of the ABBL, ACA and ALFI in Brussels. In this capacity, he is responsible for representing the three associations before the European institutions.
Antoine has professional experience with several European institutions including the Commission, the Parliament and the Council and a pure advocacy experience of 16 years.

Negotiation of the Collective Labour Agreement
ACA has been negotiating the Collective Bargaining Agreement applicable to the insurance sector since 1967. This Collective Bargaining Agreement is concluded between the trade unions (ALEBA, LCGB, and OGBL) and ACA, usually for a 3 year period. The legislation of the Grand Duchy of Luxembourg makes the Collective Bargaining Agreement a general obligation for the entire market (including companies that are not members of ACA).
