The Better homes, better air, better health event was the first stage of a multi-partner led discussion to engage the built environment and medical communities – researchers, policymakers and practitioners – in how to improve indoor air quality. The workshop brought together 62 professionals from across the research, industry, policy and third sector communities. The purpose was to encourage industry and research leaders to think about and inform future action on the solutions and knowledge needs for reducing exposure to air pollution when indoors.
