Our work goes beyond the boardroom.
We're committed to advancing sustainability where it matters most in vulnerable communities, with emerging leaders, and in the places where climate impact is already real.
Supporting Tonga, Climate Action & Circular Economy
Since 2022, ESG Strategy has proudly supported the Kingdom of Tonga in advancing its national sustainability goals. Our work includes:
- Representing Tonga's climate interests at COP28 in Dubai
- Supporting the design of a Circular Economy Strategy tailored to Pacific realities
- On-the-ground collaboration in Vava'u, focusing on waste systems and sustainable infrastructure
- Partnering with local leaders, including the Waste Authority and Government Ministers
This is not consultancy work. It's contribution. We're here for the long haul.
"Lee's guidance has been essential in shaping sustainable strategies for waste reduction and environmental protection. I deeply appreciate his commitment to our future."
ESG Strategy CEO Lee Stewart was a mentor supporting Al Gore in Brisbane, training over 900 future Climate Leaders.
Mentoring the Next Generation
We believe sustainability leadership needs to start early and it needs to be inclusive. That's why we mentor young professionals, students, and early-career sustainability practitioners across Australia and the Pacific.
Our goal is to help develop 1,000+ future sustainability leaders by 2028 through practical guidance, real-world insight, and values-led support.
This includes structured mentoring partnerships, pro bono coaching, and university engagement all focused on helping the next generation lead with impact and integrity.
Antarctic Classroom
In December 2026, our founder Lee Stewart will lead the Antarctic Classroom, a transformative 10-day expedition for Year 9–12 students and emerging leaders.
This is more than adventure. It's a commitment to connecting climate science with real-world leadership, providing hands-on research opportunities, and mentoring the next generation of sustainability leaders. Students will work alongside polar scientists, contribute to citizen science initiatives, and develop the insights and skills that will shape their future careers.
