The Greenest City in America

That's the ambitious goal that Mayor Michael A. Nutter has set for Philadelphia. Reaching it will be an opportunity to reposition and repurpose Philadelphia as a city of the future. For the first time in decades, changes beyond our borders-primarily rising energy prices, but also climate change and an emerging green economy-are increasing the value of our urban assets. Philadelphia's dense and durable stock of housing, infrastructure and amenities position us to prosper in a carbon-constrained future.

With Greenworks Philadelphia as its guide, 21st century Philadelphia will face the challenges and opportunities created by recent global shifts and reposition itself as a city of the future.
