Our vision

Our approach is driven by european and belgian policies setting greenhouse gas reduction targets to limit global warming.

Europe has set ambitious targets for 2030 to limit global warming :


  • Reduce our greenhouse gas emissions by 40%
  • Cover 32% of final energy consumption with renewable energy
  • Improve the energy efficiency of buildings by 32.5%


In Belgium, these targets have been spread across national and regional legislations through the following objectives:


  • The closure of 7 Belgian nuclear reactors in 2025
  • An increase in the share of renewable energies in final energy consumption (for example 23.6% in the Walloon Region)
  • A 70% reduction in energy consumption of buildings in 2030

In addition, many Belgian towns have joined the European Covenant of Mayors movement which aims to reduce greenhouse gas emissions by 40% by 2030.
