I'm headed to COP28, but this trip isn't just another professional obligation, it's a deeply personal mission, fuelled by a profound sense of purpose and a commitment to give a huge underdog a helping hand.
Earlier this year, I found myself in the heart of Tonga, alongside my fellow Climate Reality Mentor and Tongan Climate Ambassador, Uili Lousi. It was a moment of awakening when Uili reached out with a simple yet powerful request:
"Lee, the Kingdom of Tonga needs you."

The Devastation: A Nation Underwater
The devastation wrought by the Hunga Tonga-Hunga Ha'apai volcano in January 2022 was beyond imagination. Villages and resorts vanished overnight, and the sea unleashed a tide of plastic waste, a grim reminder of the wider world's neglect.
The Scale of the Crisis
- Entire communities destroyed in minutes
- Massive influx of plastic waste from the ocean
- Critical infrastructure damaged or lost
- A nation struggling to rebuild while facing an overwhelming waste crisis
From Corporate Constraints to National Impact
In Tonga, my role has transformed into something extraordinary: helping the nation rise above the overwhelming waste crisis.
After 20 years of feeling constrained as a corporate sustainability professional, the opportunity to apply fresh, unbridled thinking to aid a nation in desperate need has been truly liberating.
This is sustainability without the corporate red tape. No endless approval chains. No watered-down compromises. Just practical, ambitious solutions for people who need them most.
The Vision: World's First Circular Kingdom
I'm thrilled to share that we've developed an ambitious plan for Tonga to emerge as the "World's First Circular Kingdom."
Zero Waste Roadmap for Tonga by 2040
The roadmap focuses on four key pillars:
1. Robust Governance & Legal Frameworks
Policy, regulation, and institutional structures to support circular economy transition.
2. Community-Focused Education & Awareness
Grassroots engagement, behaviour change, and capability-building at every level.
3. Strategic Infrastructure Investment
Waste collection, sorting, processing facilities, and circular business infrastructure.
4. Holistic Circular Economy Practices
Designing out waste, keeping materials in use, regenerating natural systems.
Milestones: 2028, 2030, 2040
These initiatives are interlinked, with significant milestones set for the present and future:
2025-28: Quick Wins
- Fully circular glass economy (6 months)
- 30% plastic waste conversion (12 months)
- New micro-businesses and jobs created
- Community engagement programs launched
2030: Systemic Change
- Comprehensive waste infrastructure
- Circular economy in policy and practice
- Regional leadership and knowledge-sharing
2040: Zero Waste Kingdom
- Full circular economy achieved
- Model for Pacific nations and beyond
- Resilient, self-sufficient systems
Why This Matters Beyond Tonga
With proper funding and partners, we believe Tonga can go fully circular with glass within just six months, creating new micro-businesses, jobs, and a brighter future.
Give us another six months and we estimate we can turn close to 30% of the plastic waste into a viable resource.
More importantly, this project offers hope to the resilient people of Tonga and sets a precedent for other Pacific nations facing similar challenges.
Lessons for Australian Business
The Tonga project demonstrates principles that apply to any organisation:
- Start with what matters most, Focus on high-impact, achievable wins
- Engage the community, Sustainability only works when people are part of the solution
- Build circular systems, Design out waste, not just manage it
- Think long-term, act now, Ambitious vision with immediate action
- Collaborate for impact, No single organisation can solve complex challenges alone
