International Momentum on Indoor Air Quality: What Global Policy Leaders Are Doing—and What it Means for Australia’s Healthy Building Future

Indoor air quality (IAQ) has shifted from a niche technical issue to a central public health and building performance priority worldwide. Governments are increasingly focused on how to regulate, monitor and improve indoor air at scale. This presentation synthesises leading international IAQ policy approaches, drawing on examples from Europe, Asia, North America and the Middle East. It highlights emerging best practice, including enforceable health‑based standards, phased and transparency‑driven regulation, prioritisation of schools and healthcare settings, and widespread use of low‑cost CO₂ monitoring. The session offers the Australian IAQ community a clear view of where global policy is heading and how evidence, technology and regulation can combine to deliver healthier indoor environments.
