‘Reading the writing on the wall’: why Wall Street is acting on the climate crisis

The industry has backed polluters for decades. Now, amid growing pressure, Wall Street says it's going green

Wildfires burned nearly 10.4m acres across the US last year. The most costly thunderstorm in US history caused $7.5bn in damage across Illinois, Iowa, Nebraska and South Dakota. As the climate crisis swept the globe on a biblical scale it left in its wake a record number of billion-dollar disasters.

And yet out of these ashes has emerged an unlikely savior: Wall Street. After decades of backing polluters and opposing legislation to rein them in, finance says it's going green.
