GCF teams have coated or cleaned over 1 million square feet of rooftop as part of the NYC Cool Roofs campaign, built the city’s first urban farm on public housing property in partnership with the New York City Housing Authority and Added Value, and educated thousands of public housing residents about changing behaviors in their homes that can lead to energy reduction, through the Love Where You Live campaign. GCF has been recognized as a national model by President Clinton and by the White House as one of five Youth Jobs+ Champions of Change in 2013. GCF Lisbeth previously founded Unis-Cité, the leading national youth service program in France which engages over 2000 annual corps members in 50 cities and inspired national legislation affecting 75K young adults. She is an Echoing Green alum, Draper Richards Kaplan Fellow, Audubon “Woman Greening the City,” White House Youth Jobs+ Champion of Change, Yale graduate and mother of two.
