In 2014, the City of Halle signed the Covenant of Mayors for climate and energy. The city therefore hopes to save at least 20% energy and have 20% less CO2 by 2020. In the years after the city wants to work towards climate neutrality.

The two major energy consumers in the city are the public buildings and public lighting, both owned by the city.

The aim of the project is to develop a service contract for the purchase of street lighting according to the principles of the circular economy. The energy used is locally produced and supported and financed through civic participation.

The ambition is to come to a service contract in Flemish cities and municipalities in order to contribute to achieving the objectives of the Covenant of Mayors 2020.
