Holcim (US) Inc will co-sponsor the second session of Mass Impact, a two-part symposium addressing cities and climate change, on June 9. The Boston Society of Architects (BSA) and MIT’s School of Architecture and Planning will lead the symposium, which will examine "Energy and Mobility in the Green City."

Patrick Dolberg, president and CEO of Holcim, will be joining Nicky Gavron, the 2004-08 deputy mayor of London, and others to discuss the implementation and design of new technologies to yield low-impact energy and low-impact transportation systems.

Panel discussions will focus on the low-impact energy and transportation systems used in Chicago, Toronto, Seattle London, and other cities that have combined new technologies with government policies to mitigate the inefficiency of centralised energy systems and automobile traffic.
