This document discusses green buildings and their role in reducing global warming. It notes that buildings account for 38% of carbon dioxide emissions in the US. Green buildings have been shown to reduce CO2 by 33-39%, energy by 29-50%, waste by 70%, and water by 40-50%. The LEED green building certification system is discussed as a way to lower operating costs and increase asset values while conserving resources. The refitting of the Empire State Building is presented as a high-profile example, reducing its energy use by 40% and saving $4.4 million per year. The document calls for educating others on global warming and green buildings, and implementing green building codes internationally.
