@mu @stephen Belgium passed indoor air quality laws in 2022 (in response to Covid-19), and might be a reasonable place to start looking. Looks like there’s a 2026 update that requires displaying measured air quality levels in public spaces. There also seem to be some studies looking at harmonising the law across Europe (ie as an EU law not just Belgium). https://whn.global/belgium-clean-air-law-a-law-to-improve-indoor-air-quality-in-enclosed-spaces-open-to-the-public/ https://www.sciencedirect.com/science/article/pii/S0360132325014374 https://www.aivc.org/resource/iaq-label-belgian-public-spaces-monitoring-11-public-spaces
