Planting of a Tiny Forest

On Friday, 4 July 2025, the City of Luxembourg reaffirmed its commitment to protecting the climate and nature by planting a micro-forest on a plot of land adjoining the Weimerskirch cemetery. The initiative was undertaken as part of the Climate Day programme organised by Klima-Bündnis Lëtzebuerg, and brought together volunteers and children from the Eich foyer scolaire who, under the supervision of the City's Service Cimetières (Cemeteries Department), helped with the planting of 300 trees and shrubs, in a move that further enhances Luxembourg City's natural heritage. The saplings, which are around 70 cm tall, came from the "Grow Together, Grow Green" urban garden, which was designed by Topotek1 as part of the LUGA-Luxembourg Urban Garden outdoor exhibition and is an integral part of the LUGA Lab located in the heart of Odendahl Park. A further 350 trees will be planted in the Tiny Forest in autumn 2025. The planting of this tiny forest – the second of its kind in the capital – was attended by Maurice Bauer, Deputy Mayor and alderman responsible for the environment.

Particularly dense and small in size, these tiny forests feature 3 to 5 trees and shrubs per square metre, and are ideally suited to urban landscaping. The benefits of these urban forests go far beyond simply beautifying local neighbourhoods: they improve air quality by filtering dust, releasing oxygen, and remove CO₂ from the atmosphere; they cool streets and public squares by humidifying the air; and they create a rich habitat for wildlife. Not to mention the beneficial effects on people's mental and physical health. Studies have also shown that increasing the amount of small- and medium-sized green spaces that are well distributed over a given area reduces the formation of heat islands and enhances cooling.

Measures to protect the environment taken by the City

In response to the climate emergency, and to honour its commitments as set out in the College of Aldermen's 2023–2029 mission statement, the City of Luxembourg has made nature protection a top priority. To this end, the Service Forêts and Service Parcs, which are responsible for maintaining the capital's forests and green spaces, in close collaboration with our Environmental Officer, are committed to making forest ecosystems more resilient and protecting urban and park trees. But the City's environmental action is not limited to protecting the capital's existing natural heritage assets, and its aim is for more than 30,000 new trees to be planted in the capital by 2030, thanks to the efforts of City departments and state agencies.
