In 2015, the Luxembourg government named Wiltz a Circular Economy Hotspot, encouraging the city to "gradually integrate the rules of the circular economy into its building regulations and to promote the ecological construction of buildings with high added value, having a positive impact on the economy and environment".

In 2017, Wiltz took it a step further by integrating the concept of circular economy into the Official Declaration of the College of Aldermen for 2017 – 2023. In 2018, Wiltz renewed its political commitment with a Circular Economy Charter, by which it undertook to mainstream the circular economy in its future project and activities, including:

• enabling municipal services to plan and organise their activities according to socially and environmentally responsible standards;
• make a better use of the material and human resources;
• actively respect biodiversity in municipal project design;
• gradually integrate circular economy in building regulations at municipal level in order to promote eco-design and construction of high-value added buildings;
• introduce a communication strategy aimed at promoting circular economy.

The 2023-2029 political declaration keeps up this momentum, stipulating that the municipality plans to continue developing its skills in the field of the circular economy and to promote the establishment of businesses operating in line with circular economy principles.
