With Earth Day just around the corner on Sunday, one way to celebrate being green is to host a green party. This has nothing to do with politics — it’s a way to share your adoration for keeping our planet clean and to enjoy the company of friends.

Evite, the Web-based invitation site, makes it easy to forget the “open and throw away” paper invites and to instead send online invitations. In 2006, morethan 170 million Evite invitations were sent, saving more than 5.3 million pounds of paper, and 3,500 trees. Evite launched in 1998 and people picked it up right away. Eva Ingvarson, Evite’s editor and trend expert, shares her tips to host the perfect Earth Day party, while ensuring minimal impact on the environment. “Evite is great for eco-friendly parties,” she said.
