Energy and climate
As a member of Klimabündnis Lëtzebuerg since 2000, and a signatory of the Climate Pact since 2012, the City of Luxembourg has put in place a set of measures with the following aims:
- reduction in energy consumption (particularly fossil fuels)
- related reduction in CO2 emissions
- increase in the generation and use of renewable energies
- adapting to climate change
In 2017, the City adopted its initial roadmap report (Leitbild), which outlines its climate protection aims, challenges, guiding principles and implementation process. In 2023, this roadmap was adapted to take account of the new provisions of the Pacte Climat 2.0 and national climate targets. The City has therefore set itself the following targets for 2030:
- reducing CO2 emissions by 55%;
- increasing energy efficiency by 44%;
- increasing the use of renewable energies by 37%.
The City is also aiming to be carbon neutral by 2050.
Climate Pact
The City of Luxembourg has been committed to the Climate Pact since 2013.
It has made consistent progress over the years as it works towards achieving a score of at least 75%:
- on 26 May 2016, the City of Luxembourg was certified under the European Energy Award programme for the first time, having achieved a score of 54%.
- on 8 June 2018, the city was awarded Klimapakt Air Quality certification.
- on 28 November 2019 (last certification under Climate Pact 1.0), the City achieved certification level 2 with a score of 68%.
- on 21 September 2022, the City achieved certification level 3 with a score of 65% under Climate Pact 2.0.
- on 15 April 2024, the City obtained Klimapakt Air Quality certification under Climate Pact 2.0.
Monitoring energy consumption and CO2 emissions
Every year, the City of Luxembourg prepares a detailed report on energy consumption and related CO2 emissions for both the territory and the administration.
Subsidies aimed at combatting climate change
The City of Luxembourg has set up a range of different subsidies to encourage residents in the capital to join the City's efforts in protecting the environment. Residents can benefit from the partial reimbursement of costs related to measures implemented in the following areas:
- energy renovations
- renewable energies
- energy efficiency and sustainability
- electric transport
- adapting to climate change

Klima-Agence Infopoint
Klima-Agence Infopoint Stad Lëtzebuerg for residents of Luxembourg City
The Infopoint is an information and advising service covering energy, sustainable housing and mobility. It is a joint initiative of the City of Luxembourg and Klima-Agence, the national agency for the promotion of an energy transition to sustainable sources.
Its mission is to advise, inform and educate in the following areas:
- sustainable energy renovation,
- sustainable construction,
- renewable energies,
- sustainable mobility,
- everyday energy savings,
- energy performance certificates,
- the different types of grants available.
Project Building Energy Efficiency
In January 2025, the City of Luxembourg launched the BEE (Building Energy Efficiency) collaborative project with LIST and FIRIS, aimed at assessing the energy efficiency of Luxembourg City's built heritage. Residential and commercial buildings account for more than two-thirds of energy requirements and CO2 emissions in Luxembourg City, and therefore offer significant potential for reducing carbon emissions.
Precise knowledge of the energy status of buildings is therefore a key factor in achieving our climate objectives, enabling 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 relating to energy consumption and CO2 emissions associated with buildings are cross-referenced and analysed, providing a profile of 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.
