It’s been at least three days since we’ve had an eco-gala around here! Finance-in-his-pants Hank Paulson—who has that lacrosse captain-turned-bespectacled billionaire attractiveness that women inexplicably go crazy for—formerly of Goldman Sachs and now of the U.S. Treasury, joins eco-elf Michael Bloomberg at the Nature Conservancy’s “Greening the World” Spring Gala at the boastfully green Hearst Tower. (Can a company that wastes paper on Cosmo every month really be green?).

[Greening the World gala, Hearst Tower, 300 West 57th Street, 6:30 p.m., 212-763-8590]
