From green roofs to community gardens and energy efficiency to smart grids, Greater Philadelphia has established itself as an early adopter and valuable innovator when it comes to sustainable design, building, business and communities. The Delaware Valley Green Building Council and Sustainable Business Network and B-Labs have helped create a marketplace for green initiatives, while green jobs have become more than a catchphrase thanks to those working to train a new generation of workers at the Green Jobs Academy of Bucks County and Energy Coordinating Agency. The Philly-based Pennsylvania Horticulture Society and the City's Office of Sustainability Greenworks Philadelphia, along with community development initiatives across the city and suburbs, from both the non-profit and government sectors, are responsible for one of the nation's most robust examples of urban greening. The Penn State-led research consortium's development of an energy innovation hub at the Philadelphia Navy Yard promises to keep the region on the cutting edge of sustainability.
