Against a backdrop of Marcellus shale gas development, initiatives emerge for a sustainable and resilient response to the climate change and pollution challenges of the twenty-first century. People, institutions, communities, and corporations in Pittsburgh are leading the way to a more sustainable future. <br><br>Examining the experience of a single city, with vast social and political complexities and a long industrial history, allows a deeper understanding of the challenges and opportunities inherent in adapting to change throughout the world. The case studies in this book respond to ethical challenges and give specific examples of successful ways forward.
