Walloon Region, Belgium

"Our region has experienced a drop in air particle pollution since the 1990s, partly because of emissions standards and major improvements in energy efficiency and renewable energy use. We want to ensure that this momentum continues by taking action to meet our commitments under Belgium and EU legislations and standards. However, we still experience ‘pollution peaks’ under certain climate conditions, which trigger a multi-agency response, and we are also working to mitigate growing pollution from vehicles, a challenge we share with other growing regions."
