1 Month On: The Impact of Climate Action Week Sydney 2025

It’s hard to believe it’s been a month since Climate Action Week Sydney 2025 lit up our city, but the momentum hasn’t stopped. The conversations, connections, and climate breakthroughs sparked during that unforgettable week are still buzzing through Sydney and beyond.

With over 12,000 tickets snapped up and 246 events unfolding across Greater Sydney, CAWSYD25 was more than just a success; it was a movement. From sold-out forums to late-night rooftop panels, the energy was electric, and the appetite for change was undeniable.

This city-wide celebration of climate action was only possible thanks to the powerful partnerships that made it happen. Our sponsors stepped up in every way: opening iconic venues, bringing global voices to the stage, and driving bold, future-focused conversations.

One of the most inspiring highlights? Watching climate solution start-ups take the spotlight, forging new relationships with investors and changemakers. With climate innovation more urgent than ever, CAWSYD25 proved just how powerful a platform like this can be in accelerating real, lasting impact.

"We're particularly excited to see climate solution start-ups given a platform and the valuable space to connect with investors. The need for idea sharing and innovation on climate action has never been more urgent, and this is a great opportunity for passionate, solutions-oriented discussion." - Christina Hobbs, General Manager, Impact and Advocacy, Future Group

Events that went beyond the stage

From snorkels and run clubs to career fairs and pitch nights, Climate Action Week Sydney reflects the wide range of ways people engage with climate solutions.

By stepping beyond traditional formats, the week creates more inclusive and accessible entry points into the climate conversation. This year's program featured activities like ocean snorkels, morning run clubs, hands-on workshops, behind-the-scenes tours of research and development facilities, career fairs, and pitch nights.

On top of all of this, Climate Action Week Sydney celebrated a massive week with the Party for the Planet, a night for the community to connect and socialise without the heavy cognitive discussions that climate action often necessitates.
