Fashioning Change in the Big (Green) Apple and Beyond

The worlds of fashion, art and the environment don't often collide, even in New York City. But that is exactly what's happening on March 29 at the second annual Christie's Green Auction: Bid to Save the Earth -- an event that my husband David and I are proud to be hosting for the second time along with Anna and Graydon Carter and Salma Hayek and Francois-Henri Pinault.

The auction again benefits four top environmental nonprofits: Natural Resources Defense Council (NRDC), Central Park Conservancy, Conservation International and Oceana.

This year, the Green Auction includes the Vogue-supported Runway to Green, which will feature a runway show with top designers such as Derek Lam, Burberry, Marc Jacobs, Stella McCartney and many others. NRDC has been working with these designers to incorporate practices from its Clean by Design campaign, which aims to reduce the environmental impact of the textile industry.

This auction isn't just about greening the fashion industry. It's about collaborating to solve the interrelated and complex environmental problems facing our planet. It's also about celebrating the beauty of the natural world, from Central Park to the world's oceans. It's about making a bid to save the Earth.

A Bid to Save the Earth is not limited to just one night, nor is it limited to New York City. Anyone can text "GOGREEN" to 20222 to donate $10. Auction items, from one-of-a-kind celebrity experiences to eco-vacations to the latest in eco-friendly fashion, are available for bid online through the charitybuzz website and at Whether you're in the room or online, you can make your bid to save the earth.

I believe that fashion is beautiful and ephemeral, but art is forever. Our planet is somewhere in between, depending on how we act individually and collectively. No matter what your passion is -- the newest Balenciaga bag, that mesmerizing Jackson Pollock at the MOMA or bicycling around your favorite city park -- our hope for this event is to get more people involved around the world to preserve our planet for future generations.
