When your mother is Isabella Rossellini and your grandmother was Ingrid Bergman, felicitous opportunities come your way as naturally as enviable genes. And so Elettra Rossellini Wiedemann—whose parents were introduced by Bruce Weber at a photo shoot in the 1980s—was recruited as a model by the photographer when she was 19 years old.

But at 23, Elettra is now creating extraordinary opportunities all by herself. After reading *Vanity Fair'*s Green Issue last year, she proposed an environmentally conscious new program to Lancôme, where she is following in her mother's footsteps as a spokesmodel. Inspired by "carbon free" programs that encourage people to reduce carbon-dioxide emissions in one location to compensate for those they create elsewhere, Elettra asked Lancôme to sponsor her air travel through Carbonfund.org, an international nonprofit organization seeking to reduce the threat of climate change by supporting renewable energy and reforestation projects.

"They calculate your carbon footprint, and how many trees it would take to neutralize your carbon emissions," Elettra explains. "I was shocked when I realized how many trees it took to zero out my emissions. I hope this will encourage other people to take a look at their carbon footprints and start thinking about ways they can reduce their emissions."

Meanwhile, Lancôme is embracing a range of eco-chic initiatives that include the launch of Primordiale Cell Defense, an antioxidant serum that helps to protect the skin against damage caused by pollution, UV exposure, and high temperatures. In partnership with Carbonfund.org, Lancôme will plant one tree for each of the first 10,000 bottles of Cell Defense that are sold.
