Due to buildings being responsible for almost half (48%) of all fossil fuel energy consumption and greenhouse gas emissions, Edward Mazria has closed his architecture practice to focus on transforming the Building Sector from a leading contributor to climate change into a central part of the solution to this crisis. As Executive Director of Architecture 2030, he has issued the 2030 Challenge, calling for all new buildings and major renovations to reduce their fossil-fuel GHG-emitting consumption by 50% by 2010, incrementally increasing the reduction for new buildings to carbon neutral by 2030. The 2030 Challenge has been widely adopted throughout the building industry, and incorporated into city, state and federal legislation. On December 19th, 2007, Congress passed, and the President signed, the Energy Independence and Security Act of 2007, requiring that all new and renovated federal buildings meet the 2030 Challenge targets.
