The Boston Society of Architects and MIT's School of Architecture and Planning are initiating two open symposia starting in March 2008, gathering leading urbanists from the United States and overseas to frame the issues and opportunities facing the modern city in a period of global climate change and resource depletion. The goal is to establish a design and policy agenda for Boston and the New England region that benefits from best practices elsewhere and sets new standards for ensuring the environmental, economic and social sustainability of the city in a global economy.
