This week, five shortlisted teams took part in the final stage of the Net Zero Challenge – a global competition to identify, promote and support innovative, practical and scalable uses of open data that advance climate action.
The five teams presented their three-minute project pitches to the Net Zero Challenge Panel of Experts, and a live audience. Each pitch was followed by a live Q&A.
The winner of the pitch contest will be announced in the next few days.

There are many people who collaborated to make this event possible.
We wish to thank both Microsoft and the UK Foreign, Commonwealth & Development Office for their support for the Net Zero Challenge. Thanks also to Open Data Charter and the Open Data & Innovation Team at Transport for New South Wales for their strategic advice during the development of this project. The event would not have been possible without the enthusiastic hard work of the Panel of Experts who will judge the winning entry, and the audience who asked such great questions. Finally – to all the pitch teams. Your projects inspire us and we hope your participation in the Net Zero Challenge has been – and will continue to be – supportive for your work as you use open data to advance climate action.
