Pan on, Fan on: Why Your Home’s Air Quality Matters

Online event

About this Event

We invite participants to join this important discussion to explore the implications of indoor air quality in our homes and collaborate on strategies that can enhance the well-being of individuals and communities.

We spend most of our lives indoors—in our homes, schools, and workplaces. Yet, our understanding of the air we breathe within these spaces remains surprisingly limited.
Indoor air quality is a crucial aspect of environmental health, particularly since individuals spend a substantial portion of their lives indoors. The INGENIOUS project, funded by UKRI, has comprehensively studied indoor air pollution in the UK.

In January 2025, INGENIOUS released a paper on the project’s research and initiated a wider conversation on its implications for public health, housing policy, and the air guidelines. Researchers studied indoor air pollution in over 300 homes in Bradford, UK. This in-depth investigation has yielded crucial insights into the diverse range of pollutants present indoors, the significant influence of occupant behaviours, and the interplay between indoor and outdoor air quality. By developing an indoor emissions inventory, conducting extensive air quality measurements, and employing predictive models, INGENIOUS is providing a much-needed evidence base to understand and address indoor air pollutants.

INGENIOUS aims to shed light on the sources, transformations, and fates of indoor air pollutants, as well as our exposure to them. The INGENIOUS project findings are timely and relevant as the UK moves towards net-zero goals.

The event directly supports a Net Zero and Resilient UK. Understanding indoor emission sources and transformations is crucial as people spend more time indoors. By identifying these issues, we aim to provide actionable recommendations for healthier indoor environments. This builds UK resilience by protecting public health from environmental changes, while recommending responsible behaviour choices and efficient ventilation strategies that also contribute to net-zero targets.

This public engagement event at London Climate Action Week aims to:
• Raise awareness about the often-overlooked issue of IAQ and its implications for well-being
• Explore the link between occupant behaviour and IAQ.

The public event aims to leverage the global platform of London Climate Action Week, coinciding with an event on June 23, which falls just days after UK Clean Air Day on June 19, to amplify the message and connect with other relevant initiatives.

Speakers are:
• Nic Carslaw, University of York
• Nicholas Pleace, University of York
• Larissa Lockwood, Global Action Plan
. Sarah West, Stockholm Environment Institute, University of York
• Mark Mon-Williams, University of Leeds/Born in Bradford
• Catherine Noakes, University of Leeds

The findings of the INGENIOUS project provide a crucial foundation for understanding and addressing the significant challenges posed by indoor air pollution in the UK.

INGENIOUS project

Do you know what harmful airborne pollutants are found in your home?

Many of our activities in our homes produce airborne pollutants, including particles and chemicals that can harm our health. We don't know exactly where these pollutants come from, how they interact with each other or where they end up. The INGENIOUS project will investigate these unknowns and deliver beneficial interventions to limit exposure. A team of scientists led by the University of York are working together with the internationally recognised Born In Bradford (BiB) study. The team includes specialists in environmental, social, medical, engineering, economic, and health issues, from the University of York (including the York Centre of the Stockholm Environment Institute), the University of Manchester, the University of Cambridge and the University of Sheffield.
