The U.S. Agency for International Development wants to spend an eye-popping amount of money to battle climate change — but it *wants the private sector to come up with the bulk of it*, raising the question of how realistic the ambitious plan is. On the flip side, “eye-popping” is in the eye of the beholder, and others are slamming the agency for lowballing what’s needed.

The agency acknowledges both the magnitude of what it’s asking for — and that whatever it does garner is just the tip of a multitrillion-dollar iceberg. “The point of this exercise is to *turn a little money into a lot more money*,” says Gillian Caldwell, USAID’s chief climate officer. “It’s not a business-as-usual scenario at USAID right now, and I don’t think we should be expecting business-as-usual results.” But it’s tough to change the business-as-usual mindset of a behemoth bureaucracy, although some are impressed with the plan. “We are glad to see that the administration is putting some money where their mouth is,” Shaun Martin of the World Wildlife Fund says.
