About

Conference theme

The theme “21st Century Challenges” reflects the complex and interconnected forces reshaping our world and the growing need for innovative, practical and collaborative solutions to protect air quality and build environmental resilience.

Across both the Clean Air and Environment Conference and the Asia-Pacific Odour Conference, the theme invites delegates to consider two critical questions:

What is your 21st century challenge?

And more importantly, what is your 21st century solution?

As we navigate rapid technological change, urban growth, and the accelerating impacts of climate change, traditional approaches are no longer sufficient. Addressing air quality, emissions and odour in this context demands new thinking, new tools and stronger collaboration across disciplines and sectors.
