As evidenced by the major weather events that continue to threaten communities across Australia (and the world – with 2025 clocking in as the world’s third-hottest year on record), the climate crisis isn’t going anywhere. And while it’s easy to feel despondent in the face of climate change, there are incredible people and organisations taking action – harnessing modern technology, regenerative farming techniques and collective action to slow down the crisis. This month, founders, researchers, students and community organisations will be coming together in Sydney for Climate Action Week – taking over the Harbour City from March 9-15. Here's everything you need to know.
Led by the Climate Action Foundation and backed by the NSW Government, Future Super and Boundless, this year’s program doubles down on practical, community-powered action. Expect heavyweight voices at the opening day, including Climate Change and Energy Minister Chris Bowen, California Energy Commission chair David Hochschild, Climate Change Authority chair Matt Kean and former Irish president and global climate advocate Mary Robinson.
Across Greater Sydney, the week-long program spans Oceans and Water, Health and Wellbeing, Food and Agriculture, Fuels and Energy, Nature and Biodiversity, and Green Tech and Finance – with First Nations leadership and youth voices front and centre. Think snorkelling for science at a Snorkel-Out for Climate, behind-the-scenes Living Seawalls tours, an AEVA Electric Vehicle Rally, Climate Tech Careers Night and a Sport Climate Forum.
There’s also a strong Pacific focus, with events spotlighting frontline resilience in Vanuatu, and youth-led conversations unpacking what COP31 means for the next generation.
Last year, more than 12,500 people took part – double the year before. In 2026, the event is calling on Sydneysiders to turn climate anxiety to climate action.
