Energy and climate
As a member of "Klimabündnis Lëtzebuerg" since 2000, and a signatory to the Climate Pact since 2012, the City of Luxembourg has adopted a number of measures that are geared towards:
- reducing energy consumption (particularly fossil fuels)
- and thus reducing CO2 emissions
- increasing the generation and use of renewable energies
- adapting to climate change
In 2017, the City adopted its initial roadmap (Leitbild) defining its climate protection targets. In addition to describing the implementation process, the roadmap also describes the guiding principles and main challenges involved. In 2023, the roadmap was updated to take account of the new provisions of the Climate Pact 2.0 and national climate targets. The City has set itself the following targets for 2030:
- Reduce CO2 emissions by 55%;
- Improve energy efficiency by 44%;
- Increase the use of renewable energies by 37%.
The City is also aiming to achieve carbon neutrality by 2050.
Climate Pact
The City of Luxembourg has been committed to the Climate Pact since 2013.
Working towards achieving a score of at least 75% in the medium term, the City has made steady progress over the years:
- on 26 May 2016, the City of Luxembourg was certified for the first time under the European Energy Award scheme, having achieved a score of 54%.
- on 8 June 2018, the City was awarded Klimapakt Air Quality certification.
- on 28 November 2019, the City was awarded level 2 certification under Climate Pact 1.0 (its last certification under Climate Pact 1.0) with a score of 68%.
- on 21 September 2022, the City was awarded level 3 certification under Climate Pact 2.0 with a score of 65%.
- on 15 April 2024, the City was awarded Klimapakt Air Quality certification under Climate Pact 2.0.
- on 6 October 2025, the City was awarded the European Energy Award Gold label, after having achieved a score of 78.2% further to its latest Climate Pact 2.0 audit. The European Energy Award Gold label is the highest level of certification and the target that the City has set for itself as part of this programme. The City is committed to pursuing its efforts to maintain this level of excellence in future audits.
Monitoring energy consumption and CO2 emissions
Every year, the City of Luxembourg prepares a detailed report on energy consumption and associated CO2 emissions for both the local and national authorities.
Subsidies aimed at combatting climate change
The City of Luxembourg has earmarked a number of different subsidies to encourage Luxembourg City residents to join the City's climate protection efforts. As such, the City will partially reimburse any costs that residents incur for works undertaken in the following areas:
- energy-efficient renovations
- renewable energies
- energy efficiency and sustainability
- e-mobility
- adapting to climate change

Klima-Agence Infopoint
Klima-Agence Infopoint Stad Lëtzebuerg for Luxembourg City residents
The Infopoint is an information and advisory service covering energy, sustainable housing and mobility. It is a joint initiative undertaken by the City of Luxembourg and Klima-Agence, the national agency for the promotion of an energy transition to sustainable sources.
Its mission is to inform, educate and provide advice in the following areas:
- sustainable energy renovation;
- sustainable construction;
- renewable energies;
- sustainable mobility;
- everyday energy-saving measures;
- energy performance certificates;
- the different types of grants that are available.
Project: Building Energy Efficiency
In January 2025, the City of Luxembourg launched the BEE (Building Energy Efficiency) collaborative project in partnership with LIST and FIRIS, with the aim of assessing the energy efficiency of Luxembourg City's built heritage. Residential and commercial buildings account for more than two-thirds of Luxembourg City's energy requirements and CO2 emissions, and therefore offer significant potential for reducing carbon emissions.
Accurate data on buildings' energy status is therefore a key factor in achieving our climate objectives, as it enables us to implement measures to improve the energy efficiency of our building stock and accelerate the transition to renewable energies in buildings.
As part of this project, various data sets on the energy consumption and CO2 emissions associated with buildings are cross-referenced and analysed. In this way, a profile can be established for each building.
Recommendations
Update: Climate Pact – Recommendations
As a signatory to the Climate Pact and in collaboration with Ëmweltberodung Lëtzebuerg, the City of Luxembourg publishes a number of practical recommendations on its website that can help you protect the environment and take action against climate change.
