GLASGOW, Scotland — Britain has called for the world’s financial industry to channel its vast funds toward greener investments to ensure that efforts to curb global warming succeed.

Treasury chief Rishi Sunak said that the U.K. government is providing new funds to help poor countries cope with climate change. But he said that “public investment alone isn’t enough.”

Sunak called for a “historic wall of capital for the net zero transition around the world.”

But poor countries are angry that after Britain and other wealthy countries failed to meet their commitment to provide $100 billion a year to finance climate-related projects in the developing world by 2020.
