Get ready for spring at the Building Museum

Kermit the Frog was right when he sang, "It isn't easy being green."

We all want to do the right thing, environmentally speaking, but sometimes it's hard to know exactly what that is -- especially when it comes to the little household projects many of us will be turning to, now that the weather is warming up. What's the greenest paint? The most sustainable flooring material? The home improvement product with the smallest carbon footprint?

Find out today at the National Building Museum, when a panel of experts talk about "Greening the Supply Chain" from 6:30 to 8 p.m. Part of the museum's ongoing "For the Greener Good" series, the program costs $20; members get in for $12, and it's free for students.
