Just some of the quotes that City Halls gave us:
"Cities shouldn’t wait for a new optimal technology to emerge in the future to get started because there are already so many ways to get started off the shelf."
Björn Hugosson, Chief Climate Officer, City of Stockholm
"The importance is working with other levels of government, communities and the private
sector as we just can’t do it alone."
Lord Mayor Sally Capp, City of Melbourne
What is unique about the Cities Climate Action Summit?
Different from traditional city events, the Summit seeks to uncover tangible solutions—you will see and hear the latest from leading policymakers, technologists and financiers to learn what is working and what is not working.
The Summit will provide a holistic view of how urban climate action can be achieved at scale.
Why host the Cities Climate Action Summit?
Experts across the globe from the World Bank to the World Economic Forum estimate investment needed to combat the climate crisis surpasses US$90 trillion by 2030.
And cities are at the crossroad for this investment! The Summit will focus on the policy, the finance and the technology to make these investments wisely—to inform city leaders so they can work to serve and protect their citizens
