Hundreds of climate leaders are expected to flock to Sydney next year after the City of Sydney won its bid to host a global conference for women.

The C40 group, representing 94 cities home to more than 700 million people, has selected Sydney to host its Women4Climate Conference in April 2020.

Lord Mayor Clover Moore said cities are responsible for a "staggering 75 to 80

per cent" of the world’s greenhouse gas emissions, making action in cities to cut carbon pollution crucial.

“Many of the world’s biggest cities are setting ambitious targets and policies to reduce

greenhouse gas emissions, proving effective action on climate change and strong

economic growth are compatible," Cr Moore said.
