Firms that analyse climate risks are the latest hot property

SOON AFTER Hurricane Sandy battered Manhattan in 2012, Emilie Mazzacurati founded a firm in California to analyse the risks posed by climate change to business. She called it Four Twenty Seven, after the state’s target of lowering annual greenhouse-gas emissions to the equivalent of 427m tonnes of carbon dioxide by 2020. That reference quickly became outdated. The target was adjusted for technical reasons two years later, and rendered moot in 2018 by the announcement of a net-zero goal. Ms Mazzacurati is still happy with the name, though. “That is the risk of doing business in an uncertain climate,” she says.
