The climate crisis is vast, complex and often feels both imminent and frustratingly out of our control. With global systems slow to change and the scale of the challenge immense, it’s easy to wonder if individual action could ever be enough. 

On World Environment Day, Climate Warriors brings together four transformative voices; renewable energy expert and former Biden administration advisor Saul Griffith, Solar Citizen CEO Heidi Lee Douglas, climate activist Grace Vegesana along with host and journalist Craig Reucassel, to unpack the power and limitations of grassroots action, climate innovation and community-driven change. 

From local initiatives to systemic shifts, they’ll unpack what’s working, what isn’t, and where real impact is being made. While no single effort can solve the climate crisis, collective action has the potential to tip the balance. 

Hope is not passive. It’s built, fought for and sustained. So, in a time that demands action and an urgent transition to a sustainable society, how do we rise to the challenge?  

Presented by the UNSW Centre for Ideas and UNSW Engineering, in association with the Right Here, Right Now Global Climate Summit

PROGRESS FOR ALL
 

Climate change is arguably the most urgent issue of our time, with enormous ramifications for future generations.

UNSW will continue our trajectory as a leader in responses to climate change and impact mitigation from increasing natural disasters. We will enhance our expertise in climate science, environmental sustainability, disaster response and resilience, and many other related disciplines across all our faculties to influence policy and create innovative solutions with real-world impact. We will collaborate across all disciplines, faculties, sectors and borders to optimise the impact of our teaching, research and thought leadership to help create a liveable world for generations to come.

We will lead by example in working to be a climate-resilient, nature-positive and net zero emissions University.

You can read more about our objectives in our UNSW Strategy: Progress for All.

Heidi Lee Douglas

Heidi Lee Douglas’ work across advocacy, government, and filmmaking focuses on giving power to the people. As the CEO of Solar Citizens, she's led successful campaigns for state and federal home battery rebates, New Vehicle Emissions Standards, and solar for social housing, renters and apartments. Heidi believes that enabling a plurality of home power generation will create a fairer Australian economy, greater energy security and drive down carbon emissions.  

Heidi is also Deputy Mayor of Bayside Council, and an award-winning film and television Writer/Director whose work across documentary and feminist horror specialises in moving the dial. Living in one of the most diverse areas of Sydney, Heidi is constantly reminded of the challenges and opportunities to find common ground, build bridges and create a better tomorrow.
